What I'm looking for

I'm looking to apply my technical expertise and drive innovation within dynamic engineering teams.

At Velkap Co., I modernized platform features with Laravel and Next.js and designed secure REST APIs for transactional systems.

I implemented database-level multi-tenant architecture and built a pipeline that creates timeline-based snapshots of raw financial transactions, supporting consistent reporting and historical state reconstruction.

I also designed an event-driven microservices architecture for the Investor Portal using NestJS and NATS, and deployed containerized services on Azure.

Previously, I developed platform features at Flintstone Engineering and Dream Study Abroad, including Next.js interfaces, TypeScript and Express APIs, and .NET Core Web APIs.
