At CrowdUpss, I architected and developed a full-stack URL-shortening platform using React, Tailwind CSS, Node.js, Express.js, and MongoDB. It generated six-character Base62 short URLs and included URL validation, JWT authentication, route protection, and persistent user sessions.
I built Sprintly, a Kanban project management platform with a RAG system that answers natural-language queries over project data. I implemented retrieval across SQL and semantic vector search, plus board-level isolation and prompt-injection safeguards.
For Vybe, I developed a distributed social platform using independently deployable services and event-driven communication with Apache Kafka. I also used Redis caching and benchmarked the system against a monolithic baseline, achieving up to 9× higher throughput and reducing API latency by up to 85%.
