What I'm looking for

I am looking for senior backend/cloud roles where I can design scalable data pipelines and serverless architectures, mentor teams, and solve complex engineering problems.

I am a senior software engineer with 16 years of experience building backend systems, data pipelines, RESTful APIs, and cloud-based serverless infrastructure across Healthcare, eCommerce, IoT, and automotive domains.

I have architected real-time AWS-based applications processing tens of gigabytes per day, designed IoT analysis systems for 100+ sensors, and implemented large-scale web crawlers and ETL workflows for major retailers. I combine strong backend expertise (Django, Flask, FastAPI), data tooling (NumPy, Pandas, Scikit-learn), and DevOps/cloud practices (AWS, Docker, Kubernetes) to deliver reliable, scalable solutions.

I value pragmatic design, automated testing, and clear collaboration with cross-functional teams to resolve technical and design issues; I seek opportunities where I can architect systems, improve data workflows, and mentor engineers to produce production-grade software.
