Saad Siddiqui

Full-Stack & Mobile Engineer | MERN · Next.js · React Native · Electron · Go
With nearly a decade of hands-on software engineering experience, I specialize in architecting and delivering production-grade applications across web, mobile, and desktop — from early-stage MVPs to fully scaled SaaS platforms.
My core stack spans the full product lifecycle:

Frontend: React.js, Next.js (SSR/SSG/App Router), Tailwind CSS, headless CMS integrations
Mobile: React Native (cross-platform iOS & Android, Expo & bare workflow)
Desktop: Electron.js (cross-platform desktop apps with web tech)
Backend & APIs: Node.js, Express, Go (Golang) — RESTful and GraphQL APIs built for scale
Database & Infra: MongoDB, PostgreSQL, Redis, Docker, AWS/GCP

I've led and contributed to multiple SaaS products — designing multi-tenant architectures, implementing subscription billing flows, building role-based access systems, and optimizing for performance at scale. I care deeply about clean architecture, maintainable codebases, and shipping things that actually work in production.
Whether you need a founding engineer who can own the full stack, or a specialist to level up a specific part of your system — I'm comfortable working independently or integrating into existing teams.
Let's build something solid.
