What I'm looking for

I'm looking to build scalable AI-enabled products and complex distributed systems, contribute to architecture and product decisions, and mentor teams while delivering reliable customer-facing outcomes.

At OneOrigin, I led the zero-downtime migration of 15 institutional clients to AIRR V2, integrating Salesforce, Banner, LeadSquared, Recruit, and SFTP through a strategy-pattern connector framework.

I architected modular microservices with Fastify, TypeScript, Next.js, and MongoDB, improved deployment efficiency by 35%, and built ORC, a graph-based workflow engine that reduced transcript-review effort by 40% across 35+ clients. I also implemented Amazon SQS event publishing, Elasticsearch search, and Google Document AI and Gemini-based extraction to improve credential-data accuracy.

Previously, I built a Layer-2 blockchain job portal at Examroom.ai and booking and profile-management products using React.js, Node.js, and modern backend systems. I enjoy turning complex product ideas into reliable, scalable software and mentoring engineering teams through architecture and delivery.
