Hi, I'm S.M. Hazrat Ali
Full-Stack Engineer · React · Next.js · Node.js · TypeScript · AWS · Docker · CI/CD · Terraform · MongoDB · PostgreSQL
From code to cloud I design, build, and deploy production-ready web applications end to end. I build fast, responsive interfaces with React, Next.js, and TypeScript; develop APIs and real-time services with Node.js and Express; and build reliable backend systems with MongoDB, PostgreSQL and Redis. I take applications from the first commit to production using Docker, GitHub Actions, Terraform, and AWS from deployment automation and cloud infrastructure to reliable releases. I build mainly with Claude Code and Cursor: scoped specs, parallel agents, and line-by-line review and testing before anything ships. Currently on a contract and available to transition into a new role immediately.

Full-Stack Engineer
Firmwide — PriceEstimator.ai
- Primary engineer for a project-fee estimation and billing platform built with React 19, TypeScript, Vite, TanStack Query, Tailwind CSS, Radix UI, Node.js/Express 5, MongoDB, and Redis.

- Built REST APIs with Express 5, Mongoose, Redis, JWT, and Zod for enquiries, proposals, invoicing, authentication, and user management, with a caching strategy to reduce database load.
- Architected a domain-driven frontend of about 450 TypeScript/React files with vertical-slice modules and enforced import boundaries.
- Added Microsoft single sign-on (MSAL), Microsoft 365 mailbox ingestion through Microsoft Graph, role-based access control, OTP-based invitations, and real-time Socket.IO notifications.
- Set up GitHub Actions CI/CD with lint, type-check, and build gates on pull requests, tag-based staging-to-production promotion, multi-stage Docker builds, and environment-specific Nginx reverse-proxy configs.
- Use Claude Code and Cursor as the main development environment: scoped specs, parallel agents across API, UI, and test work guided by CLAUDE.md rule files, and line-by-line review before merging.
