What I'm looking for

I seek a mid‑to‑senior engineering role building scalable backend and web/mobile systems, with collaborative teams, CI/CD practices, and opportunities to improve performance and reliability.

I am a full-stack developer with 3+ years building production-grade web applications, backend services, and mobile features for thousands of users. I have led architecture and implementation of Node.js/Express services, introduced Redis caching layers, containerized deployments with Docker and Kubernetes, and optimized databases and APIs to significantly reduce latency and improve reliability.

I collaborate across product, QA, and frontend teams to deliver features on schedule, implement CI/CD to accelerate releases, and integrate third-party services including payment gateways and logistics APIs. My work has improved response times, lowered operational costs, and scaled user-facing functionality for web and React Native mobile users.
