### We scope before we build
Every engagement starts with a structured discovery phase. User story mapping, data model design, API contract specification and performance benchmarks are defined in writing before a line of code is written. If it is not in the scope document, it does not appear in the sprint.
### Architecture designed for where your business is going
We design application architecture with your 12-month and 36-month growth in mind. Database schemas that accommodate volume growth, API designs that support integrations you have not planned yet and cloud infrastructure that scales without manual intervention from your operations team.
### AI capabilities are integrated where they add genuine value
We build AI-powered features where the use case justifies the integration. Document processing, intelligent search, recommendation engines, workflow automation and predictive analytics. We benchmark every AI feature against the deterministic alternative and recommend the simpler approach when it is more reliable.
### Handed over to you, not held by us
Every application includes full documentation: architecture diagrams, API specifications, database schema, deployment runbooks and environment configuration guides written for the developer who inherits the codebase. We run a formal handover session and remain available for 30 days post-launch.
## Our Custom Web Application Development Services
From a focused internal operations tool to a multi-tenant SaaS platform with AI-powered workflows, here is what we build.
- Web applications built around your specific business process. Customer-facing portals, internal workflow management tools, data visualisation dashboards, booking platforms and marketplace applications. Built on React or Next.js, Node.js or Python, PostgreSQL or MongoDB, deployed on the cloud infrastructure your organisation already uses.
- Customer Portals
- Workflow Management Tools
- Data Dashboards
- Booking Platforms
- Marketplace Apps
- AI capabilities are integrated at the feature level. Intelligent document processing, vector search, recommendation engines, natural language interfaces and LLM-powered workflow automation. We integrate OpenAI and Anthropic Claude where the use case justifies it and benchmark every AI feature against its deterministic equivalent before recommending it.
- LLM Integration
- Document Processing
- Vector Search
- Recommendation Engines
- OpenAI and Claude
- SaaS products built on a multi-tenant architecture from the first sprint. Multi-tenant PostgreSQL, subscription billing through Stripe or Chargebee covering the full lifecycle, plan-based feature gating through a centralized entitlements system and an onboarding flow built around your product’s specific value moment.
- Multi-Tenant Architecture
- Stripe and Chargebee
- Feature Gating
- Onboarding Flow
- Subscription Billing
- Enterprise web applications that meet the security and compliance requirements your IT and procurement teams enforce. Active Directory and SSO integration, role-based access control in the data model, audit logging and compliance architecture for HIPAA, SOC 2, GDPR or CCPA built from discovery, not retrofitted after a security review.
- SSO and Active Directory
- Role-Based Access Control
- HIPAA and SOC 2
- Audit Logging
- GDPR and CCPA
- Legacy applications your business depends on, but that cannot be extended or integrated with modern tools. We assess before recommending. Sometimes an API layer is the right answer. Sometimes a phased rewrite is lower risk. We show you the options with honest effort estimates for each path.
- Legacy System Assessment
- API Layer Build
- Phased Rewrite
- Strangler Fig Migration
- Tech Debt REST and GraphQL APIs OpenAPI Specification CRM Integration ERP Integration Webhook MiddlewareReduction
- REST and GraphQL APIs built to standards that third-party developers can integrate with from the documentation alone. Consistent endpoint naming, standard error formats, OpenAPI specifications and versioning strategy. Plus integration middleware connecting web applications to CRM platforms, ERP systems, payment processors and data warehouses.

##### Discovery and requirements documentation
Structured engagement that produces requirements document precise enough to build from , user stories with acceptance criteria, data models, API contracts, integration requirements, non-functional requirements (performance, uptime, compliance), and a prioritised feature backlog. Signed off by your team before design begins.
- User Story Mapping- Data Model Design- API Contracts- Acceptance Criteria- Signed-Off Scope
##### Architecture design
A technical design document covering data model, API design, infrastructure topology, security model, integration architecture, and performance design, reviewed and approved by your team before development starts. Architecture decisions are cheap to change in a document and expensive to change in a live application.
- System Architecture- API Design- Infrastructure Topology- Security Modelling- Performance Architecture
##### Sprint-based development with visible progress
Two-week sprints with working software at the end of each sprint. Not status reports. Staging environment access from sprint one. Backlog visible in your project management tool in real time. Sprint review attended by your product owner, not just your project manager.
- Two-Week Sprints- Staging Environment- Live Backlog Access- Working Software Every Sprint- Transparent Progress
##### QA against requirements, not against a demo
Every acceptance criterion in the requirements document is tested before sign-off. Every integration is verified against the live third-party system. Every user role was tested for correct permission boundaries. Performance testing under expected concurrent user load. Security review against your applicable compliance framework.
- Acceptance Criteria Testing- Integration Verification- Role-Based Access Testing- Permission Boundary Checks- Pre-Launch Sign-Off
##### Handover that transfers real ownership
Architecture documentation, API specifications, database schema documentation, deployment runbooks, environment configuration guides, and a formal handover session. Followed by a 30-day post-launch support window for issues that real-world usage surfaces.
- Architecture Documentation- API Specifications- Deployment Runbooks- Handover Session- 30-Day Post-Launch Support
### Backend: Node.js, Python, Laravel
Node.js with Express or NestJS for API-first backends. Python with Django or FastAPI for data-intensive applications and AI integrations. Laravel for teams with existing PHP expertise. Stack selected to fit your requirements and your team’s capability, not what we built the last project in.
Node.js Express and NestJS Python FastAPI Django Laravel
### Databases: PostgreSQL, MongoDB, Redis
PostgreSQL for relational data models. MongoDB for document-oriented data where schema flexibility is genuinely required. Redis for caching, session management and rate limiting. Database chosen for the data model, not the trend.
PostgreSQL MongoDB Redis pgvector ACID Compliance
### AI and ML: OpenAI, Anthropic, LangChain
OpenAI API and Anthropic Claude for LLM integration. LangChain and LangGraph for agent orchestration. Pinecone, Weaviate and pgvector for vector search. Scikit-learn and PyTorch for custom model development. Integrated as feature-level services with their own API contracts.
OpenAI API Anthropic Claude LangChain Pinecone RAG Architecture
### Cloud and Infrastructure: AWS, GCP, Azure
AWS for most deployments. GCP where BigQuery or Vertex AI is a primary requirement. Azure for enterprise clients with Microsoft infrastructure. All deployments are infrastructure-as-code with Terraform, containerised with Docker and deployed through GitHub Actions CI/CD.
AWS ECS and RDS Terraform Docker GitHub Actions CI/CD Auto-Scaling
### Testing and Quality Assurance: Jest, Playwright, Cypress
Jest for unit and integration testing across Node.js and React codebases. Playwright and Cypress for end-to-end testing of critical user flows. Test coverage written as part of every sprint, not as a separate phase at the end of the project. Every release passes automated checks before it reaches your staging environment.
Jest Playwright Cypress End-to-End Testing End-to-End Testing
### Security and Compliance: OWASP, Auth0, Okta
Security architecture built from the start, not reviewed after the first vulnerability audit. OWASP Top 10 coverage across every application we build. Auth0 and Okta for enterprise identity and SSO integration. Data encryption at rest and in transit as a baseline. Role-based access control designed into the data model, not added as middleware after the application is live.

### B2B Technology and SaaS
Multi-tenant SaaS platforms, customer-facing portals with enterprise SSO, internal operations platforms, API-first backends for third-party developer ecosystems and AI-powered workflow automation tools. We understand multi-tenancy, subscription billing lifecycle management, plan-based feature gating and the API design standards enterprise customers expect.
[ Contact us ](https://www.krishaweb.com/contact-us/) 
### Healthcare and Health Tech
B2B enterprise applications need access control that reflects organisational hierarchy, audit trails that satisfy compliance requirements and integrations to the ERP and CRM systems that already run the business. We build B2B applications with role and permission systems designed from the data model up, SSO integration for enterprise identity providers and API integrations that handle the edge cases that only appear when real business data flows through them.
[ Contact us ](https://www.krishaweb.com/contact-us/) 
### Financial Services and Fintech
Healthcare web applications carry specific obligations around data handling, access logging and system integration that general development work does not address. We build healthcare applications with HIPAA-aware data architecture, role-based access that limits patient data exposure to the minimum necessary, audit trails that satisfy compliance review and HL7 and FHIR integration patterns for connecting to EHR systems.
[ Contact us ](https://www.krishaweb.com/contact-us/) 
### Real Estate and Property Technology
Property management platforms with lease management, maintenance request workflows and financial reporting. Investor reporting platforms, MLS integration layers, transaction management platforms for brokerages, AI-powered valuation tools and document management systems for the contract-intensive workflows real estate transactions generate.

## Frequently Asked Questions
We hope these questions and answers help you find the best web app development partner.
- A focused internal tool or portal with three to five features typically ranges from $20,000 to $60,000. A multi-tenant SaaS platform ranges from $60,000 to $150,000. An enterprise application with complex integrations can range from $100,000 upwards. Fixed price confirmed after requirements documentation, not before.
- A focused application typically takes 12 to 20 weeks from discovery to launch. A SaaS platform typically takes 20 to 32 weeks. An enterprise application with compliance review can take 6 to 12 months. Timeline confirmed after the requirements documentation phase.
- A website presents information. A web application processes data, responds to user actions, stores state, enforces business rules and connects to a database and external services. The distinction matters for architecture, cost and timeline.
- Yes, unconditionally and from the first commit. IP assignment agreement signed before development starts. All code, documentation, schemas and API specifications transfer to you. Development happens in your repository. There are no proprietary KrishaWeb frameworks in your codebase.
- Yes. We start with an assessment of your existing architecture to identify the cleanest integration points, prototype the AI feature against your actual data before committing it to the architecture and integrate it as a discrete service so the rest of your application runs independently of LLM availability.
- Yes. We start with a codebase audit covering code quality, test coverage, documentation, security vulnerabilities and architectural soundness. We show you an honest assessment and a remediation plan. Some codebases need targeted improvements. Others are cheaper to rebuild than to maintain, and we will tell you which.
- React or Next.js for frontends, Node.js or Python for backends, PostgreSQL for relational data and AWS for cloud infrastructure, all with TypeScript, Docker and GitHub Actions CI/CD. We also work with Laravel, MongoDB and integrate AI using OpenAI, Anthropic Claude and LangChain where the use case justifies it.
- Your dedicated project manager and lead developer are aligned to working hours, available for your standup, sprint review and ad hoc questions during your business day. Project communication runs through your tool of choice: Slack, Teams or Linear.
