Vivek Mangukiya
Backend developer · Across Gujarat
From Surat, I build Node.js and TypeScript backends for organisations across Gujarat — the CRMs, inventory, billing and donation systems that keep several locations, warehouses or departments working from the same data.
Why me
Many organisations in Gujarat have grown from one location to several — and their software hasn't kept up.
A distributor with godowns in two cities, a manufacturer with a factory in an industrial estate and a sales office in town, a trust running collections across several centres — the challenge is rarely a single screen. It's keeping stock, money and records consistent when several people in several places are changing them at the same time.
That's the problem I've spent most of my time on: multi-warehouse inventory with transfers and purchase orders, donation CRMs with receipts and staff roles, billing with GST and reports that finance can trust. The backend is where those rules either hold or quietly fall apart.
Branch- and warehouse-aware data models, transfers that can't lose stock, and reports that roll up across locations.
Most work happens over calls and Git. For kick-off workshops or go-live, I can travel within Gujarat.
Staff can explain their process in Gujarati; the specs, code and documentation stay in clear English.
Typed code, consistent structure and documented APIs, so your in-house team or next vendor can work on it.
Services
Typical engagements across Ahmedabad, Vadodara, Rajkot, Gandhinagar and the rest of the state.
Purchases, sales, purchase orders and inter-warehouse transfers, with stock that stays correct at every location.
Donor records, campaigns, online donations via Razorpay, receipts and staff permissions for religious, educational and charitable trusts.
Leads, customers, orders, approvals and role-based access — added module by module instead of one risky big-bang rollout.
Daily, monthly and branch-wise reports, plus Excel and PDF exports for owners, accountants and auditors.
Payment gateways, email providers and third-party APIs connected with proper error handling and retries.
Slow queries, inconsistent data or fragile code reviewed and fixed — with a written summary of what changed and why.
Selected work
Inventory across warehouses, donations across campaigns, billing across currencies — systems built around many moving parts.
Inventory & CRM
Multi-warehouse paper inventory CRM covering purchases, sales, transfers, purchase orders, roles and operational reporting.
Donation CRM
Donor CRM for collections, receipts, campaigns and staff roles — with Razorpay payments and reporting for day-to-day operations.
Billing & inventory
Billing and inventory platform with GST, multi-currency invoices, stock sync, Razorpay payments, PDF invoices and Excel reports.
Process
Distance within the state is rarely a problem — this is how I keep projects moving.
A video call — or an on-site visit for larger projects — with the people who run each location or department.
I document how each branch, warehouse or centre works today and where data needs to be shared or kept separate.
Start with one module or one location, prove it in daily use, then extend — so operations never stop.
Walkthroughs for admins, API docs for developers and a support window agreed in advance.
