The part your users never see — but feel every time they click. Microservices, REST APIs, queue systems, caching layers, and infrastructure that handles real production load without falling over.
Clean, versioned, documented APIs built with FastAPI (Python) or Express (Node.js). Auto-generated Swagger/OpenAPI docs, input validation, rate limiting, and CORS config out of the box.
Break monoliths into independently deployable services. Each service owns its data, scales independently, and fails without taking down the whole system.
BullMQ + Redis for job queues. Heavy tasks (email sending, PDF generation, image processing, webhook delivery) run in background workers so your API stays fast.
Schema design, indexes, query optimisation, connection pooling. Slow queries identified and fixed. Database migrations managed safely with Alembic (zero downtime).
Redis caching for repeated queries, session storage, and rate limit counters. The difference between a 2000ms response and a 20ms response on the same data.
AWS Lambda and Vercel Edge Functions for event-driven workloads — webhooks, scheduled jobs, image resizing on upload, email triggers. Pay per execution, scale to zero.
