I’m a full-stack engineer with 5+ years building and scaling B2B SaaS and fintech products. I’m comfortable across the stack—React and Next.js on the frontend, and Node.js and Golang on the backend—shipping end-to-end features that support real transactional volume.

At Mayar Kernel Supernova, I joined as the 3rd engineering hire and grew into a senior individual contributor and project lead, reporting directly to the CTO. I shipped 30+ end-to-end product features across payments, e-commerce, e-learning, memberships, and events, including migrating the public-facing app to Next.js with SSG and a GraphQL data layer.

I optimize what matters: I improved checkout API response time from ~10s to ~1s by reworking the Redis caching strategy and request flow. I integrated the Xendit payment gateway across frontend flows and backend reconciliation logic, migrated a core API service from Golang to Node.js (Express), and built new API/cron/queue-based services for asynchronous processing—while designing database schemas and writing complex backend logic with direct SQL in an existing multi-tenant platform.
