Eliminate Technical Debt. Accelerate Velocity.
Legacy systems shouldn't hold your business back. We migrate mission-critical applications without interrupting active customer transactions.
Legacy Monolith to Cloud-Native Microservices
Break down brittle legacy architectures into modular, independently deployable microservices with zero downtime, event-driven messaging, and clean domain boundaries.
- Domain-Driven Design (DDD) service decomposition
- Event-driven architecture with Kafka, RabbitMQ, and AWS SQS
- Database strangler-pattern migrations with dual-write safety
- Containerized deployments with Docker and Kubernetes
High-Throughput Python Engineering
Enterprise Python systems designed for computational scale, concurrency, and clean maintainability across FastAPI, Django, and asynchronous Celery workers.
- Asynchronous I/O with Python asyncio and uvloop
- Clean architecture & hexagonal software patterns
- PostgreSQL query optimization, partitioning & indexing
- Redis caching layers & distributed locking systems
Cross-Platform Mobile Apps (React Native)
Single-codebase iOS and Android applications that feel completely native, with smooth 60fps animations, offline-first SQLite sync, and secure biometric authentication.
- Offline-first synchronization for field and POS staff
- Native device hardware integration (Bluetooth printers, scanners)
- Push notifications & real-time WebSocket subscriptions
- Automated mobile build releases via Fastlane and Expo EAS
Modern Next.js & React Web Portals
Blazing-fast responsive web applications with sub-second page loads, accessible UI design systems, and robust state management for complex B2B workflows.
- Next.js App Router with server-side rendering & static caching
- TypeScript type-safety from database schema to UI components
- Tailwind CSS design systems with dark/light theme support
- Role-based access control (RBAC) and SSO authentication
Cake Mania Manufacturing ERP System
Built on AWS cloud infrastructure with Python backend and React Native mobile app for Kolkata-based client Khaliq Zaman. Manages end-to-end recipe costing, franchise orders, live delivery tracking, raw material stock, and employee shifts.
