About me.
I'm a Senior Backend Engineer at Easebuzz, designing the payment APIs banks integrate with and engineers ship to production. I'm also an AWS Certified Solutions Architect — meaning the cloud infrastructure I design isn't just fast, it's provably secure, resilient, and cost-optimised. Before fintech, I built neuroimaging platforms at a research centre and enterprise SaaS across global clients.
I write about distributed systems, security patterns, and AI Security in public — because the best way to understand a system deeply is to document it precisely enough that someone else could break it.

Beyond the Day Job: A PostgreSQL Deep Dive into Payment Ledger Internals
MVCC, append-only ledgers, idempotency race conditions, index-only scans, autovacuum bloat experiments, and a live point-in-time recovery drill — everything I learned stress-testing a payments ledger from the inside.
Cron at Scale in Fintech: Architecture Decisions, Failure Modes, and the Engineering Discipline Behind 1M+ Daily Financial Transactions
Most engineers treat cron jobs as second-class citizens. In financial infrastructure, a failed settlement cron is a regulatory violation. A double-execution is money moved twice. Here is the engineering discipline — failure taxonomy, architectural decisions, trade-offs, and quantified business outcomes — from running 40+ scheduled financial jobs at 1M+ transactions/day on Django and PostgreSQL.
Module 1 Complete: 11 Tools, 18 Days, and the Mindshift That Changed How I See Every System I've Ever Built
18 days. 11 tools. Zero external dependencies. This is the definitive retrospective of Module 1 — documenting how 6.5 years of building production systems didn't prepare me for the moment I stopped asking 'how does this work?' and started asking 'how do I force this to fail?'
Featured Work
A selection of high-impact engineering projects.
Fintech Middleware & Gateway Engine
High-Scale Payment Infrastructure Engineering at Easebuzz
A sophisticated middleware architecture sitting between merchants and payment gateways to handle high-volume traffic for UPI, NetBanking, and Cards. The system ensures secure communication and data integrity across diverse banking protocols.
Zenero
