What I'm looking for

I seek a role building cloud‑native, scalable systems where I can own end‑to‑end features, improve performance, and mentor teams.

I am a full‑stack engineer with over 5 years of experience building responsive front ends with React/Next.js and scalable backends using Node.js, TypeScript, and Python. I design cloud‑native systems with Kubernetes and Docker, optimize data handling with PostgreSQL, MongoDB and Redis, and implement event‑driven features using Kafka to improve performance and user engagement.

I have led end‑to‑end efforts including real‑time engagement, data pipelines with Apache Spark (Java), analytics dashboards, and IoT backend work. I focus on delivering robust solutions that enhance system performance, enable actionable insights, and provide measurable user impact.
