Backend that
stays up.
I'm Saad Sulmi M — a full-stack developer who builds Node.js APIs, models data in MongoDB, and runs resilient AWS serverless workflows for fintech, where reliability isn't optional.
Numbers that shipped
The engineer behind the endpoint
Three years in, I've learned that the interesting problems live on the backend — in the aggregation that won't scale, the integration that times out, the workflow that needs to survive a partner API going down.
At Stucred I build the Node.js services behind a lending product: complex MongoDB pipelines, Redis-backed performance work, AWS Lambda and Step Functions, and the verification rails that move a loan from application to approval.
I care about clean code, fast queries, and integrations that just work — and I'll happily jump to React and Redux when the frontend needs the same rigor.

Deployment history
- Built and maintained RESTful APIs in Node.js & Express for scalable lending backends.
- Designed complex MongoDB aggregations for reporting and data processing.
- Integrated 10+ third-party APIs — ICICI, YBL, CRIF, Authbridge, ZoopOne, Khosla, Firebase, Twilio & more — for verification and communication.
- Cut query times with indexing and Redis caching; automated KYC with AWS Rekognition.
- Engineered Lambda + Step Functions with retry logic for resilient serverless workflows.
- Self-taught full-stack development through hands-on web app builds.
- Developed secure Node.js APIs with authentication and data validation.
- Tuned query performance with MongoDB indexing.
- Explored serverless architecture and third-party integrations independently.
- Mentored peers on React.js and Node.js best practices.
Things I've built
Dating Platform
An algorithm-driven matchmaking app with real-time chat, video calls, and premium subscriptions. RESTful APIs connect a React + Material UI frontend to a Node backend, with Cloudinary handling media.
E-commerce Website
A full storefront with cart, wishlist, checkout, and returns. EJS + Bootstrap lifted page-load speed ~15%, AJAX powers real-time updates, and an Express backend trimmed API response times ~20%.
