The backend is where products quietly succeed or fail. A clean API and a well-modeled database make every future feature easy; a messy one makes every feature a fight. I build backends that stay easy to extend as the product grows.
I lead backend development for a microservices product spanning Django, FastAPI and NestJS, defining service boundaries and API contracts for web and mobile clients. Backend engineering is the core of what I do, not an afterthought to the frontend.
One API, every client
Your website, your iOS app, your Android app and your future partner integrations should all talk to one well-designed API, not duplicated logic per platform. I design that contract carefully, with token-based authentication, versioning and clear documentation, so business logic lives in one place and stays consistent everywhere.
The right tool for the job
Django when you want a complete, batteries-included product fast, with its admin and ORM. FastAPI when you need lean, high-performance async APIs, especially around AI workloads. Node.js with Express or NestJS when a single language across the stack makes sense. I have shipped production systems using all of them, often side by side, and I pick based on your product rather than habit.
Data modeled properly
PostgreSQL under almost everything: relational data, JSON, full-text search and vector embeddings for AI, in one engine that scales far past most startups' needs. I model your data with the audit trails, constraints and indexes that keep it correct and fast under real load.
The parts that keep it stable
Slow work belongs in background jobs, not the request cycle, so users never wait: I build this with Celery, RabbitMQ or queue workers depending on the stack. Real-time features run over WebSockets backed by your database as the source of truth. Authentication uses OAuth2 done correctly. None of this is glamorous, and all of it is what keeps a product up.
Who this is for
Teams that need a backend built or rescued: a new API for a growing product, a legacy service refactored, or the infrastructure behind a mobile app. If the backend is the bottleneck, this is the fix.
What you get
- A clean, documented API that serves your web app, mobile apps and future integrations from one place
- A well-modeled PostgreSQL database with an audit trail where it matters
- Secure authentication, background jobs and real-time features built to production standards
- Load handled properly: indexing, caching and async workers instead of hopeful scaling
