What I'm looking for

I’m looking to build full-stack, scalable products—integrating SSO/eSign, designing serverless microservices, and improving frontend performance—while shipping reusable tools and learning through production-impact engineering.

I’m a Product Engineer focused on building end-to-end platforms across frontend and backend systems. At Wysbryx Technology, I built a recruitment and employee lifecycle platform and integrated SSO and eSign APIs using AWS Lambda-based serverless microservices and event-driven workflows.

I care about performance, maintainability, and testing. I improved frontend performance with React Query, lazy loading, and code splitting, and I refactored legacy modules to improve scalability and maintainability.

I also enjoy creating reusable tools and models—publishing production-ready npm packages and building a type-safe analytics toolkit for ClickHouse in TypeScript. Beyond that, I developed a lightweight HTML-to-PDF rendering engine in Go and fine-tuned a DenseNet-169 model for image classification (90% test accuracy) using PyTorch and AWS SageMaker pipelines.
