I like systems with moving parts I can reason about — queues, pipelines, role boundaries.

THE HUMAN BEHIND THE SYSTEMS

Curious enough to explore. Technical enough to ship.

Final-year Computer Science student focused on AI/ML who enjoys the engineering between the idea and the deployed product: APIs, queues, containers, role boundaries, data stores and observability.

Alongside product work, I keep sharpening problem solving — 400+ DSA problems and a 5-star HackerRank achievement are part of the journey.
