AI Engineer — production backend systems, LLM pipelines, computer vision.
3+ years building things that ship: payments infrastructure at Razorpay (100M+ users), LLM evaluation tooling at Weights & Biases, fintech APIs at Possible Finance, and applied CV research with a peer-reviewed publication. Currently an AI Software Engineering Intern at W&B while holding two MS degrees (Computer Science + IT Management).
AI/ML systems — RAG pipelines, LLM evaluation frameworks (W&B Weave), vector similarity search with Pinecone, adversarial robustness testing, and model deployment at scale.
Computer vision — adversarial ML on medical imaging (DenseNet-121, NIH ChestX-ray14), object detection, Grad-CAM explainability, FGSM/PGD attack pipelines.
Backend — FastAPI/Flask microservices, REST APIs, AWS (Lambda, EC2, S3), Docker/Kubernetes, PostgreSQL, Redis, Oracle. Built systems handling millions of daily payment events at Razorpay.

Ship something working first — then make it better. Every project here started as a first commit, not a finished product. I'd rather have something real in front of people than a perfect version that never ships.
Fortune favors the brave.
