About this gig
Still running your business on spreadsheets?
When operations outgrow Excel, data goes missing and scaling stops. I build a custom CRM and ERP designed around how your business actually works, not a template you bend to fit.
See it before you buy it: I build a clickable prototype of your system first. You walk through real screens and sign off on the workflow before any backend is written.
Already shipped: a 12-module ERP in production, covering sales, inventory and warehouse, purchasing, production, QA, dispatch, finance, and HR, with role-based access.
What I build:
Custom CRM - leads, pipeline, clients, follow-ups, quotations
Inventory & stores - stock, reorder alerts, lot tracking, transfers
Operations - orders, planning, production, dispatch
Finance - invoicing, receivables, cost, and margin per job
AI agents - lead scoring, stock alerts, and document extraction, on your own data
Stack: Next.js, React, Node, Django, PostgreSQL, OpenAI, and Anthropic APIs.
Start with my $100 Basic Package for a clickable UI prototype + technical blueprint (100% credited toward your full build!).
Message me your workflow (even a messy Excel) to get started.

FAQ
1 — Which package is right for me?
Message me before ordering — two lines about your business and what you use today (Excel, Tally, other software) is enough. I'll recommend the right package honestly, including telling you if a smaller one covers your need.
2 — Can you migrate our data from Excel or Tally?
Yes. Data migration from Excel, Tally or your current software is scoped into every Standard and Premium build. You get a verified import, not a copy-paste.
3 — Do you handle manufacturing-specific needs like BOM, work orders and production planning?
Yes. Bills of materials, work orders, production planning, QA, and dispatch are core to what I build. My largest delivery is a 12-module manufacturing ERP running in production (see portfolio).
4 — Do we own the source code?
Fully. You receive the complete source code, database and deployment documentation. No lock-in, no monthly license fees.
5 — Where is it hosted? Can we use our own server?
Your choice: your own cloud account (AWS, DigitalOcean, etc.), a server on your office network, or I set up affordable hosting for you. Either way the system and its data belong to you.
6 — Can multiple companies or branches run on one system?
Yes. My most recent delivery runs two companies on a single ERP with separated data and role-based dashboards (see portfolio). Multi-branch and multi-godown are standard.
7 — Does it work on mobile?
Yes — the system is a responsive web app, so it works in any phone or tablet browser without installing anything. A dedicated native app can be quoted separately if you need one.
8 — Can we add more modules later?
That's the recommended path: start with the modules that hurt most, extend when they've proven themselves. The system is architected so later modules plug into the same data and user accounts.
9 — How do revisions work?
Each package includes revision rounds on the agreed scope — refining what we specified together. New features beyond that scope are quoted as a separate custom offer, so there are never surprise charges in either direction.
10 — What support do we get after delivery?
Every build includes 30 days of post-delivery support for fixes and questions. After that, a monthly maintenance retainer is available for ongoing changes — or your own team can take over, since you have the full source and docs.
