I’m a Software Development Engineer focused on building microservices and data platforms that solve real performance, reliability, and developer-experience challenges. Right now, as a Software Development Engineer - 3, I’m implementing changes that directly reduce latency, eliminate bottlenecks, and strengthen system correctness under load.

As a Founding Engineer (Software Development Engineer - 2), I spearheaded the architectural design and development of the entire product line from scratch. I established core microservices and data platforms, including an asynchronous Hook Orchestrator microservice with NestJS and RabbitMQ to drive high-scale automated job executions across HTTP, Slack, and Email.

I’ve also built infrastructure that keeps systems fast and safe: a Dynamic Schema Engine using TypeORM/Knex.js for metadata-driven PostgreSQL table generation and automated migrations without system downtime. To ensure correctness at scale, I diagnosed database deadlocks and connection pool exhaustion and implemented deterministic locking and transaction propagation strategies.

At Vymo, I served as Member of Technical Staff and delivered enterprise-grade services for banking and lending workflows. I architected loan and collections processing, implemented multi-channel notification integrations, built an organizational hierarchy engine with region-based RBAC for 10,000+ users, and reduced manual QA effort by 80% through a BDD-driven CI/CD pipeline (TestNG + Cucumber), aligned with RBI regulatory guidelines.
