What I'm looking for

I seek a senior engineering role building cloud-native, AI-driven products with strong engineering practices, mentorship opportunities, and scalable impact.

I am a Full Stack Engineer with 9+ years designing and delivering scalable, cloud-native applications using Python (Django, Flask, FastAPI), React.js and TypeScript. I lead cross-functional teams to build high-performance systems, optimize delivery timelines, and implement AI-driven features.

My work spans backend scalability, frontend experience improvements, DevOps practices, and machine learning integration — from training LLMs with RLHF to deploying microservices on AWS and Kubernetes. I have repeatedly reduced delivery time, lowered technical debt, and increased system reliability through testing, CI/CD and automation.

I am committed to building high-impact products that combine strong engineering discipline with pragmatic business outcomes, mentoring teams, and continuously improving systems for performance, observability, and user experience.
