Vivek Mangukiya
Backend developer · Surat, Gujarat
I'm Vivek Mangukiya, a Node.js and TypeScript backend developer based in Surat. I design APIs, databases, payments and integrations for local businesses — and I can sit across the table from you while we work out what the system needs to do.
Why me
Most backend problems start as a conversation about how the business actually runs. That conversation goes faster in the same room.
I've been building backend systems in Surat since December 2022, currently at Codezee Private Limited. Day to day that means REST APIs, MongoDB and PostgreSQL schemas, role-based access, and the unglamorous production features — PDF invoices, transactional email, payment callbacks, reports — that a team relies on every morning.
Surat runs on trading, manufacturing and service businesses where the real rules often live in a ledger, a WhatsApp group or one senior person's head: job-work entries, stock across godowns, GST on every bill, staff who need different permissions. My job is to get those rules out of people's heads and into a backend that applies them the same way every time.
We can meet at your office — Vesu, Adajan, Varachha, Udhna or anywhere in the city — and walk through the workflow with the people who actually do it.
Explain the process in whichever language your team is comfortable with; specs and API docs are written in clear English.
Validation, predictable errors, safe payment handling and readable logs — not just endpoints that pass a demo.
Everything lives in your Git repository with setup notes, so you are never locked in to one developer.
Services
Most projects are one of these — or a mix of a few.
Node.js, Express and TypeScript APIs for web apps, admin panels and mobile apps, with authentication, roles and clear error responses.
Invoices with GST, multi-currency where needed, stock that updates on every sale or purchase, PDF bills and Excel exports for your accountant.
MongoDB, PostgreSQL or MySQL schemas built around your real records — and help untangling an existing database that has grown messy.
Razorpay and other gateways with proper webhook handling, plus email receipts, reminders and PDF documents.
Inherited a half-finished project from another developer or agency? I can audit it, stabilise it and keep shipping on top of it.
Role-based staff panels for orders, stock, bookings or leads — so operations stop living in spreadsheets.
Selected work
Billing, inventory and booking backends — the same kind of operational software Surat businesses use every day.
Billing & inventory
Billing and inventory platform with GST, multi-currency invoices, stock sync, Razorpay payments, PDF invoices and Excel reports.
Inventory & CRM
Multi-warehouse paper inventory CRM covering purchases, sales, transfers, purchase orders, roles and operational reporting.
Booking & CRM platform
Booking and CRM system for events, venues, staff, packages, leads and customer bookings — with availability checks and automated emails.
Process
Small, visible steps — you see working software early and often.
An in-person meeting or call to understand who uses the system, which records matter and which rules can never break.
A short document listing modules, data models and endpoints, so we agree on what is being built before code is written.
Working endpoints and screens every week, demoed on a staging server — at your office if that's easier.
Production deployment, environment notes and API documentation, plus a support period agreed up front.
FAQ
Send a short note about what you're building or what's broken. I usually reply within one business day, and we can meet in person if that's easier.
