What I Build

Full stack development means owning the entire product. From database schema design and API architecture to UI components and deployment pipelines, every layer gets the same attention. I build with Next.js and React on the frontend, Node.js or NestJS on the backend, PostgreSQL and Supabase for data, and Docker for consistent deployments. Projects range from SaaS platforms with multi-tenancy and billing to e-commerce systems with inventory management. Every codebase is structured to be handed off, extended, and maintained without friction.

AI integration goes beyond wrapping an API call. I build RAG pipelines that retrieve accurately from your proprietary data, LangChain and LangGraph agents that plan and execute multi-step tasks, and chatbots that maintain conversation context without ballooning API costs. The stack typically includes OpenAI or Anthropic models, vector databases for semantic search, FastAPI for the inference layer, and Redis for caching. Systems I have shipped handle thousands of queries per day with circuit breaker protection, tiered caching, and structured logging so you can actually debug when something breaks.

Web scraping is not just about getting data once. It is about building systems that run daily, handle site changes, bypass rate limits, and store results cleanly. I use Playwright, Selenium, and Puppeteer depending on the target site complexity, and architect scraping jobs with Celery and Redis so they scale horizontally. Browser automation handles anything that requires logging in, filling forms, or triggering UI events. Data pipelines connect scrapers to databases, transformation layers, and downstream consumers with proper error handling and alerting.

Good APIs are predictable, fast, and a pleasure to integrate against. I build REST APIs with FastAPI and NestJS that have consistent error shapes, proper HTTP semantics, automatic OpenAPI documentation, and auth baked in from day one. Performance matters: database query optimization, connection pooling, Redis caching for hot paths, and pagination patterns that do not fall apart at scale. Third-party integrations like Stripe, Telegram, Twilio, Google APIs, or anything with a REST endpoint, get wrappers with retry logic, timeout handling, and structured logging so failures are easy to debug.
