What I'm looking for

I seek a technical leadership role where I can own architecture, modernize systems, mentor engineers, and deliver reliable, scalable event-driven platforms.

I am a Lead Full-Stack Engineer with 8+ years building scalable, distributed, event-driven systems across enterprise domains. I focus on owning system architecture end-to-end, modernizing legacy platforms, and delivering reliable backend services and modern web applications.

My work spans frontend and backend development using React, Next.js, TypeScript, Node.js, and Python, and I design event-driven pipelines using Kafka and Redis Streams. I have deployed containerized microservices to Kubernetes and used cloud platforms like AWS and GCP to achieve resilient infrastructure.

I have led teams as a technical owner — driving architectural decisions, refactoring legacy components, improving performance and operational reliability, and mentoring engineers. Notable outcomes include CI/CD automation that cut deployment time by 60% and improved platform reliability by 80%.

I build production-grade systems with strong observability, retries/DLQ patterns, rate-limiting and deduplication, and design extensible integrations and provider adapters. I seek to contribute technical leadership and hands-on engineering to mission-critical distributed platforms.
