• ⚡ Fun: optimizing DB queries, designing fault-tolerant systems, and improving CI pipelines

I focus on backend engineering: API design, database modeling, system reliability, and observability. I prefer small, maintainable services with thorough tests and reproducible builds.

Core areas

• API Design & Implementation (REST, OpenAPI, gRPC)
• Data & Storage (Postgres, Redis, query optimization)
• Observability & Testing (logging, metrics, integration tests)
• DevOps-friendly (Docker, GitHub Actions, CI pipelines)

Backend-focused repositories demonstrating my API design, authentication, and system architecture skills.

• secure-auth-api — A production-grade REST API for user registration, login, JWT-based authentication, and role-based access control. Includes password hashing, refresh tokens, Docker setup, and PostgreSQL integration.

• task-manager-service — A clean microservice that manages tasks with CRUD APIs, validation, pagination, and caching (Redis). Includes CI/CD (GitHub Actions) and integration tests.

• payment-gateway-simulator — A mock payment API handling transactions, validation, error handling, and retry logic. Demonstrates robust design and failure recovery.

• event-driven-orders — Event-driven microservice using Kafka (or RabbitMQ) for order creation and status updates. Shows async communication, message queues, and clean service boundaries.

• monitoring-metrics-demo — Example service instrumented with Prometheus + Grafana + logging middleware for performance and request metrics.

• Clear API contracts (OpenAPI/Proto) and migration-safe DB changes.
• Tests: unit + integration tests with CI on PRs.
• Small, focused commits and clear PR descriptions.

• ✅ Reproducible Docker build + docker-compose for local dev
• ✅ GitHub Actions CI that runs tests and lint on PRs
• ✅ At least one integration test that runs with an in-memory or test DB
