COMMERCE OPS
Cashfree, Razorpay, DTF Printing, 240+ GSM Sourcing
Moving between the server room and the packing table.
I believe great modern brands are not built on marketing alone. They are forged through clean, resilient technology, obsession over physical product quality, and rigorous operational execution.
At Garibzz, my day flips between two essential worlds:
- The Engineering Room: Designing sub-second responsive catalog pipelines, real-time in-browser apparel customizer canvas tools, and bulletproof payment reconciliation with zero floating-point rounding vulnerabilities.
- The Operating Floor: Inspecting the tactile density of 240+ GSM loopknit French Terry fabrics, calibrating DTF color vibrancy, managing vendor accounts, and ensuring orders ship on time across India.
Good software is quiet. When checkout never hiccups and products feel premium in hand, trust takes care of itself.
“People may never know my name. They don’t have to. If the software and products I build make someone’s daily experience effortless, that is enough.”
FLAGSHIP PRODUCTION STARTUP // COMMERCE ENGINE

An independent D2C streetwear brand and interactive commerce engine blending regional Bengali typography, unapologetic graphic aesthetics, and an in-browser real-time design customizer.
THE TECHNICAL CHALLENGE
Deliver instant page loads across product variants while powering an interactive customizer canvas with high-resolution vector export and zero checkout drops.
SYSTEM ARCHITECTURE
Decoupled MERN stack, distributed image transformation with ImageKit CDN, dual-rail payments (Cashfree & Razorpay), and memory-tuned cloud backend.
OPERATIONS & SOURCING
Direct mill apparel sourcing (240+ GSM pure combed cotton), custom DTF printing curation, vendor settlement ledger, and nationwide courier routing.
SYSTEM DESIGN
2026
Distributed Multi-Tenant SaaS Architecture
A production-ready blueprint exploring tenant schema isolation, granular RBAC (role-based access control), and transactional billing middleware designed for high resilience.

01
Zero Silent Failures
If a payment rail disconnects or a webhook arrives out of order, the transaction doesn't disappear. Idempotent retries, persistent outboxes, and strict reconciliation protect customer trust.
02
Fast By Default
Users don't forgive a 3-second spinner on mobile 4G. We optimize asset payloads at the CDN boundary, stream state updates, and eliminate memory bloat before code reaches production.
03
Physical Quality First
Code serves physical reality. If the fabric shrinks after one wash, the best checkout funnel in the world won’t save the brand. We insist on 240+ GSM heavyweight loopknit cotton.
04
Float-Safe Math
Never use floating-point numbers for currency calculation. Integer pennies and strict server-side order total verification eliminate rounding leakage and arbitrage risks.
