Work That
Speaks Numbers

Six real projects — payments, gaming, delivery, compliance, travel, and infrastructure — each measured by outcomes, not effort.

Payments Fast-Growing Gaming Platform · India 2022 – 2024

Smarter Payments That Never Miss

Fewer failed payments, lower processing costs, and zero manual work — at millions of transactions per day across one of India's fastest-growing platforms.

What We Built

The platform was losing revenue every time a payment gateway slowed down or failed. We built a system that watches every gateway in real time and automatically routes each payment to whichever option gives the best chance of success. If a payment fails, it retries through a backup instantly — invisible to the customer. Billing is reconciled automatically at month end, with no manual work.

The Problem

One payment provider was doing all the work. When it had issues, payment failures spiked — costing the platform revenue and frustrating users at the worst possible moment (mid-game).

What Changed

Payments now flow through the best-performing provider at that moment. Failed attempts switch to a backup in milliseconds. Monthly costs are tracked and reconciled automatically — no spreadsheets.

Business Impact

+15%More Payments Succeed
−20%Lower Processing Costs
−12%Fewer Support Complaints

The Engine Behind Every Tournament Win

Players join, compete, and get paid — instantly. We built the backend that makes real-time gaming feel effortless, even with millions of transactions happening every day.

What We Built

When a player taps "Join Tournament", a lot has to happen in under a second — their entry fee is deducted, their spot is confirmed, the leaderboard updates live, and when the game ends, winnings hit their wallet automatically. We built all of that. From tournament setup to prize payout, the entire game loop runs on this backend — reliably, at scale, every day.

The Problem

When thousands of players joined a tournament at the same moment, the system buckled — delayed entries, duplicate wallet deductions, and leaderboards that were seconds out of date. Players noticed, and complained.

What Changed

We rebuilt the system to handle bursts gracefully — wallet actions are now atomic (no duplicate charges), leaderboards update in real time, and the platform auto-scales to match any spike in players.

Delivery App Hyperlocal F&B Platform · India 2020 – 2021

Order Food. Track It Live. Done.

A full delivery platform — from the moment a customer orders to the moment it arrives at their door, with live tracking, happy merchants, and rewarded riders.

What We Built

We built the entire delivery experience end-to-end — customers see their order move on a live map, merchants get a clean dashboard to manage orders, and riders get assignments directly on their phone. We also connected the platform to Uber's API so riders could earn bonus rewards for completing Uber rides, driving engagement on both sides.

The Problem

Getting a new restaurant onto the platform took days of back-and-forth. Customers had no visibility once they placed an order. Reward campaigns required someone manually updating spreadsheets.

What Changed

Merchants now go live in under 5 minutes using a self-serve portal. Customers track their order on a live map. Rider rewards are calculated and applied automatically, no spreadsheets.

Compliance & Automation Real-money Gaming Platform · India 2022 – 2023

Tax That Handles Itself

Saved ₹3 Crore a year, cut fraud by 30%, and brought tax filing errors from 10% down to 0.1% — with zero manual steps, fully automated.

What We Built

Every time a user wins money on a real-money gaming platform, there are legal tax obligations — TDS deductions, GST calculations, income tax filing. We automated the whole thing. Users get verified once (PAN + bank account), and from then on every withdrawal, deduction, and tax certificate is handled automatically. The compliance team went from spending days on monthly filing to getting a Slack message that says "done".

The Problem

The team was manually filing tax forms every month — and getting it wrong 1 in 10 times. Fraudulent withdrawals were slipping through. Users without a verified PAN could still withdraw, creating legal exposure.

What Changed

Withdrawals now require verified identity before they go through. Tax deductions happen automatically at the point of payout. Certificates are generated and filed without anyone lifting a finger.

Business Impact

Travel & Booking B2B Travel Platform · India 2019 – 2020

Book Flights & Hotels, From Any Device

Rebuilt a sluggish travel platform into a fast, app-first experience — 500+ businesses using it within the first month of launch.

What We Built

A corporate travel platform where agents book flights and hotels for their clients. We rebuilt it from scratch — search results now load in under a second, payments work reliably, and the whole experience is available as a native app on iPhone and Android. Businesses can book, manage, and get GST invoices without calling anyone.

The Problem

The old platform took over 4 seconds to show search results. There was no mobile app. Payments sometimes went through twice. Agents were calling support to complete basic bookings.

What Changed

Search results load fast, payments never duplicate, and the platform works beautifully on phone. Agents can complete a full flight + hotel booking in under 2 minutes, on any device.

A Platform That Was Slowing Down — Made Fast Again

Cleared years of data bloat, made every page and query 40% faster, and did it all without taking the platform offline for a single minute.

What We Built

As a platform grows, its database accumulates years of old records that nobody reads anymore — but they slow down every query that matters today. We built an automated cleanup process that quietly moves old data to cold storage every night, keeping the live database lean and fast. The platform never went offline. Users never noticed — they just experienced a noticeably faster product.

The Problem

The database had grown to 480 GB over the years. Core pages were loading slowly. The engineering team knew the database was the bottleneck, but couldn't touch it without risking taking down a live platform.

What Changed

We designed a process that cleans up old data in small batches, overnight, without interrupting anything. The platform shrank by 65% in size, queries got 40% faster, and nothing went down.
