FULL-STACK DEVELOPER · KOLKATA, INDIA
13 years reading fabric.
Now I read code the same way.
I spent a career in garment pattern technology before I became a full-stack developer. Today I build multi-tenant SaaS — shopkeeper ledgers, print-order platforms, mosque finders — for India's small and informal businesses, one PHP & MySQL stack at a time.

PIECE 02 — ABOUT
Two crafts, one instinct.
I started with a B.Tech in Apparel Management Technology and spent 13 years drafting patterns, grading sizes, and building tech packs for the garment industry — work that trains you to see a finished product as a system of precise, repeatable rules.
That instinct carried straight into software. I now design and build multi-tenant SaaS products for India's informal sector — shopkeepers, print shops, mosque committees, madrasas — on a deliberately unglamorous stack: PHP 8, raw PDO, a custom MVC, deployed on ordinary shared hosting. No paid frameworks, no unnecessary dependencies — the same discipline a pattern master uses: cut only what the garment needs.
Off the keyboard, I still work with Richpeace CAD and Valentina for parametric pattern development, and I'm currently learning Optitex PDS — the bridge between the two crafts is still very much active.

PIECE 03 — PATTERN MASTERY
The craft the code is built on.
13 years on the cutting-room floor, not just at a CAD screen. This is the part most developers can't offer.
Pattern drafting
Manual & CAD block development — bodice, sleeve, trouser, kurta & panel construction from base measurements.
Grading
Multi-size grading across full size ranges, rule-based and CAD-assisted.
Marker making & nesting
Fabric-efficient lay planning to minimise cutting waste at production scale.
Tech pack development
Spec sheets, BOM, construction & measurement charts ready for a factory floor.
Sample & fit review
Iterative fit correction before bulk cutting — the same QA instinct I now bring to shipping software.
CAD digitizing

Common questions.
What people usually want to know before starting a project.
Do you take on freelance web development work in Kolkata?
Yes. I work with clients across Kolkata, Barasat, Howrah, Hooghly and the rest of West Bengal, and remotely across India. Most projects run remotely over WhatsApp and calls, and I travel for in-person meetings when a project needs it.
What is a garment pattern technician, and how is that relevant to software?
A pattern technician turns a design into precise, production-ready pattern pieces: drafting base blocks, grading across sizes, planning markers for fabric efficiency, and writing tech packs. I spent 13 years doing this before moving into software — which is why the systems I build for garment factories and tailoring shops match how the work is actually done on the floor, not how a developer imagines it.
What technology do you build with?
Mostly PHP 8 with a custom MVC and raw PDO, on MySQL or MariaDB, deployed to ordinary cPanel shared hosting with no build pipeline. Laravel where a project calls for it. The stack is chosen so clients can host cheaply and I can hand over a codebase that doesn't depend on paid services.
Can you build software for a garment factory or tailoring shop?
Yes, and it's the work I'm best suited to. I've built TailorFlow for garment and tailoring shops, New Stitching Studio for made-to-measure and agent commissions, CostGen for garment costing and work orders, and SuperNest — a garment factory ERP with automatic pattern and marker making.
