What I'm looking for

I’m looking for a team where I can own technical problems end-to-end—building scalable web products, API-driven integrations, and reliable data pipelines—while continuously optimizing performance and production reliability from concept through deployment.

I’m a Full-Stack Software Engineer with 5+ years of experience building scalable web products, data-intensive systems, and API-driven architectures. I translate complex backend data into intuitive frontend user experiences while taking complete ownership from concept to production.

At STRIAT, I delivered full-stack applications using TypeScript, Next.js, React, Node.js, and PostgreSQL—covering everything from data modeling and API design to production deployment. I built and maintained REST APIs for onboarding, account management, transaction workflows, and operational processes, and I designed PostgreSQL tables and analytical reporting views to power transaction history, customer balances, aging analysis, and business metrics.

I also build reliable data and integration pipelines: a multi-stage data processing engine with exact matching, reference-based matching, and FIFO allocation; asynchronous processing with BullMQ and Redis; and normalized models from external APIs and webhook systems. Across roles (Hexcore and Hagocloud Technologies), I implemented JWT authentication with refresh tokens and role-based access control, optimized database performance, and contributed to debugging, monitoring, incident response, and continuous improvement.
