Problems I solve

Engineering capabilities

Backend architecture and APIs

I design maintainable APIs and system boundaries around product needs and expected change.

Node.js · NestJS · TypeScript · REST APIs · System design

Data and performance

I optimize real workloads and design high-volume processing that stays within clear resource bounds.

PostgreSQL · MongoDB · Redis · Query optimization · High-volume processing

Distributed systems and integrations

I build failure-aware provider boundaries and asynchronous workflows with safe retries and clear ownership.

RabbitMQ · Background processing · Provider integrations · Idempotency · Retries

Production and delivery

I ship, observe, and investigate backend systems across the full production lifecycle.

Docker · Linux · Nginx · CI/CD · Observability · Incident investigation
