What I'm looking for

I seek senior engineering roles building AI-enabled, data-driven platforms where I can drive scalable architecture, mentor teams, and deliver measurable performance and reliability improvements.

I am a seasoned full-stack developer and BI specialist with over a decade of experience building data-driven systems, enterprise integrations, and AI-enabled applications across e-commerce, government, finance, healthcare, and telecommunications.

I design and implement scalable backend services, microservice architectures, and ETL/data warehouse solutions, and I have led teams delivering high-performance platforms using Python, C#, .NET, FastAPI, Flask, Snowflake and Matillion.

My recent work centers on AI SaaS and RAG-enabled systems, distributed workflow orchestration, and real-time inference pipelines, with measurable improvements in performance, reliability, and developer productivity.

I bring a pragmatic, results-oriented approach to engineering, emphasizing test coverage, async optimization, and maintainable architectures that enable rapid product delivery and operational stability.
