I've built and scaled SaaS applications across backend and frontend systems, with a focus on Node.js, REST APIs, microservices, and secure authentication.
At LehLah, I reduced average REST API latency from four seconds to under 500 milliseconds and built Paid Collaboration Campaign and Creator Earnings Details features using Node.js, SQL, and React.
At SignDesk, I designed 50 scalable microservice APIs for core SaaS workflows, reducing API response time by 25%. I also helped migrate monolithic systems to microservices, cutting deployment time by 40%.
I've implemented SAML-based SSO, cloud-storage integrations for OneDrive and Google Drive, WhatsApp notifications, CI/CD pipelines, and Dockerized services. I also write technical design documents, investigate production issues, and mentor junior engineers.
