👋 I'm Rashik
I'm a software engineer who enjoys building systems end to end: backend, frontend, and the infrastructure that ties them together. I'm currently at Insight Global, working with NCR Voyix on the next-generation self-checkout systems deployed across more than 10,000 stores. There I built the payments backend for WIC (a U.S. government food-assistance program) and worked extensively on improving the reliability of those checkout machines.
Before this, I spent close to four years at Animall, an agritech startup, where I helped the platform grow to over 10 million users and more than a billion requests a month. I built their quick-commerce marketplace from the ground up, and took on a good deal of the less visible work as well, like bringing a 45-second analytics query down to under a second.
I'm genuinely drawn to the harder problems: distributed systems, performance, and understanding why something behaves the way it does. More recently I've been exploring applied AI. I built an internal tool that runs a retrieval pipeline and AI agents over our Jira tickets and logs to surface the likely root cause of a bug, saving the team several hours a day. Outside of work, I like to build for the sake of learning; my latest project is a distributed key-value store based on Raft, which I took on to properly understand how consensus works.
Experience
Senior Fullstack Engineer
Jul 2025 - PresentInsight Global (Client: NCR Voyix)
Working on the next-generation self-checkout systems deployed across more than 10,000+ stores, running the backend services behind millions of transactions each day.
- • Built the payments backend for WIC (a U.S. government food-assistance program) in NestJS and Go, enabling eligible shoppers to check out across more than 10,000 stores.
- • Brought the error rate on tender processing in the checkout machines down from 35% to 5% by carefully refactoring a substantial amount of legacy code.
- • Built an internal bug analyzer (Electron with a RAG pipeline over our Jira tickets and GCP logs) that retrieves similar past issues and then dispatches agents to diagnose the likely root cause, saving the team four to five hours a day.
Software Engineer II
Aug 2021 - Jul 2025Animall
An agritech startup I helped grow to over 10 million users and more than a billion requests a month, where I owned several core product areas end to end.
- • Built the quick-commerce marketplace from the ground up (inventory, orders, and payments), opening a new revenue stream for the company.
- • Established the monetization side of the product: subscription billing and ad revenue that increased ARPU by 25% and generated over $500 a day from ads.
- • Rewrote the feed using MongoDB aggregation pipelines, reducing query time from 8 seconds to 200ms and improving session engagement by around 15%.
- • Resolved a 45-second analytics query affecting our 10M+ users through better indexing and query rewrites, bringing it down to under a second.
- • Led the frontend migration from jQuery to Next.js, cutting page load times by 40% and improving checkout conversion by 12%.
- • Built a reusable Razorpay payments SDK adopted across the product, reducing the effort to add payments to a new feature from two weeks to a day.
- • Mentored four engineers through pairing and code reviews, halving onboarding time and reducing production bugs by 40%.
Software Engineer I
May 2021 - Aug 2021Zoho
A brief tenure on Zoho Assist, their remote-support product used by over 500,000 businesses. I left after four months to join Animall as an early engineer.
- • Built remote copy/paste (key simulation) for Assist using Electron and C++ native bindings, reducing related support tickets by 20%.
