What I'm looking for

I seek backend or data-science roles building scalable APIs and data-driven products in collaborative teams that value mentorship, growth, and measurable impact.

I am a results-driven backend developer and data scientist with over five years' experience building scalable web applications and APIs using Node.js (Express), PHP (Laravel), and Python (Flask, FastAPI, Django), and managing MongoDB, MySQL, PostgreSQL, Redis, and Memcache for performance and reliability. I have designed and deployed full-stack projects including an Airbnb clone, TeaOrb e-commerce, School Management App, and FixDRide, and led delivery as Senior Software Engineer where mentoring and curriculum work improved retention/performance by ~35%.

I translate data into actionable insights with pandas, scikit-learn and Power BI and enjoy mentoring developers to grow technical skills; I am seeking roles building scalable APIs and data-driven products within collaborative teams that value mentorship and measurable impact.
