What I'm looking for

I seek backend or ML-focused roles where I can build scalable, secure systems, work with cross-functional teams, and deliver measurable product and business impact in a collaborative, growth-focused culture.

I am a results-oriented Backend Engineer with nearly four years of experience designing and delivering secure, high-performance web applications, primarily in the iGaming domain (Casino, Lottery, Sportsbook). I build scalable microservices, integrate payment gateways (fiat & crypto), and deploy systems on AWS, with hands-on expertise in Python, Django, FastAPI, Flask, PostgreSQL and related tooling.

I have led cross-functional teams, reduced provider onboarding time through reusable modules, and contributed to GLI-compliant sportsbook platforms with real-time feeds and high-throughput transaction handling. I am expanding into Machine Learning and Generative AI (PyTorch, Scikit-learn, Hugging Face) and deploy ML models via FastAPI, while maintaining a focus on clean, modular code and measurable business impact.
