What I'm looking for

I seek engineering roles building scalable backend or full‑stack systems with strong team collaboration, CI/CD, cloud deployment, and opportunities to lead technical projects.

I am a Software Development Engineer focused on building scalable full‑stack and backend systems using React, Next.js, Node.js, TypeScript, PostgreSQL, Redis, Docker, and Kubernetes. I have delivered production‑grade applications used by thousands, strong expertise in DSA (250+ LeetCode), OOP, real‑time systems, and system design patterns.

My projects include SaaS analytics, real‑time collaborative tools, PWA invoicing used by small businesses, and high‑throughput document processing that won hackathon awards. I produce reliable, deployable systems with authentication, billing, real‑time features, and CI/CD practices to drive measurable product outcomes.
