About

Full-stack engineer with experience at Zoho and Amazon who has owned production systems end-to-end, including a monolith-to-microservices migration using Kafka and Cassandra that improved search latency ~25% and increased throughput without data loss. Also built a hackathon project (Buildwise) into a sold product for a construction company (AI-driven document compliance checks) and shipped an IoT-based parking availability MVP in 3 weeks.

Key Strengths

• Owned and shipped an end-to-end production history management system (frontend, backend, deployment)
• Led migration from monolith to microservices with Kafka pipeline and Cassandra storage
• Improved search latency by ~25% (reduced to ~one-fourth of prior time)
• Built high-throughput ingestion with no lag/data drops under heavy load
• Designed worker/consumer + transformer services for scalable, maintainable data processing
• Shipped an IoT-based parking availability MVP in ~3 weeks under ambiguous requirements
• Built and sold a hackathon-origin product (Buildwise) to a construction company
• Modernized monolith into queue-driven microservice with reliability patterns (idempotency, retries, DLQ, monitoring)
• Delivered measurable search performance improvement (60ms to 15ms per 1000 records; ~75% faster) and reduced maintenance overhead
• Strong cross-functional stakeholder communication tailored to product/support vs engineering leadership using data and PoCs
• Systematic debugging across software + hardware + networking on Raspberry Pi (CPU/thermal/I-O isolation) with robust validation
• Designed customer-extensible search/ranking via config + plugin hooks (avoids hard-coded customer logic)
• Built and optimized large-scale AWS data workflows for tens of millions of events/day with cost/performance improvements
