Md Nakibul Hosen Nahid · MERN Stack Developer
I build production-grade web apps & SaaS.
6+ years turning ideas into shipped software — from pixel-perfect React interfaces to resilient Node.js & Express APIs. Creator of VetVertex, a SaaS serving veterinary clinics in production.
How I Can Help
Whether you're hiring for a team or have a project to ship, here's where I add the most value — end to end, or wherever you need a hand.
Full-Stack Web Apps
End-to-end MERN applications — from database design and APIs to a polished, responsive React UI. One person, whole stack.
SaaS & MVPs
Turn an idea into a launched product. I've built and shipped a live SaaS (VetVertex), so I know how to go from zero to paying users.
APIs & Backends
Scalable, secure REST APIs and server logic with Node.js, Express, and SQL/NoSQL databases — built to grow with your traffic.
React Frontends
Fast, interactive, accessible interfaces with clean, maintainable component architecture and pixel-perfect execution.
Selected Work
A mix of what I've built on my own and the professional work I've shipped with teams.
Personal Projects
Designed and built end-to-end — from first commit to production.
VetVertex
A full-stack web application for veterinary clinics to manage appointments, patient records, and billing. Built from scratch to production with a focus on responsive design and user-friendly interfaces. Serving veterinarians and vet clinics in production since June 2026.
Case Studies
lockProfessional · NDAImpact from company and client work. Technical specifics are generalized to respect confidentiality, so these focus on the architecture and outcomes rather than proprietary detail.
Meditation App — Backend & Admin
Built the backend and admin panel for a meditation app single-handedly and shipped it in under two months. The platform now serves 200k+ users.

Built a sales CRM that pulls customer conversations from Instagram and WhatsApp into one place so the team can track every lead — moving the sales org off spreadsheets and onto a purpose-built web app.
