I build the systems that move money — from three ONDC Financial Services Buyer Apps I took live from scratch (Hamaramall, BuddyLoan, EasyCred) to scalable fintech infrastructure processing 100K+ daily transactions, and AI-augmented engineering pipelines that make teams ship 40% faster.

Who I Am

Engineering Fintech
at Scale

From multi-tenant financial infrastructure to ONDC Financial Services — turning complex domain problems into production-grade software.

I'm a results-driven software engineer with 5.5+ years of hands-on experience — starting as an intern in January 2021 — building and scaling systems inside India's fast-moving fintech ecosystem. I've shipped code that processes 100K+ daily financial transactions and taken three ONDC Financial Services Buyer Apps live from scratch, holding myself to a bar where reliability, performance, and compliance aren't optional.

I specialise in Java, Spring Boot, React, and AWS — and I've been one of the earliest engineers in my teams to deeply integrate AI-powered development workflows using Claude and ChatGPT, cutting delivery timelines by 40%. I'm currently deepening my AI toolkit with RAG pipelines, LangChain, LangGraph, LangSmith, the OpenAI API, and embeddings.

I thrive at the intersection of backend engineering, product thinking, and system design — translating ambiguous financial requirements, from ONDC lending journeys to gold loan products, into elegant, scalable solutions that compound in value over time.

How I Think

Engineering Philosophy

The principles that guide every system I design, every PR I raise, every architecture decision I own.

01

Understand the domain first

Code is the last thing I write. Before any implementation, I deeply understand the financial or business domain — because wrong assumptions at this stage compound into expensive bugs.

02

Ship fast, never blind

Speed matters in startups, but never at the cost of observability. Every system I build ships with monitoring, alerting, and the ability to debug at 3am without guesswork.

03

AI amplifies, not replaces

I use AI tools aggressively — but always as a multiplier for my thinking, not a substitute. I own every line of code, every design decision, every tradeoff.

04

Simplicity is a feature

The best architecture is the one your team can maintain confidently at scale. I actively resist unnecessary complexity and refactor toward clarity, not away from it.

Domain Knowledge

Deep Fintech Expertise

Not just a coder — a fintech engineer who understands the regulatory, business, and technical layers of India's financial stack.

ONDC Financial Services Ecosystem

Owned three ONDC Financial Services Buyer Apps — Hamaramall, BuddyLoan, and EasyCred — end-to-end: architecture, Beckn Protocol integration, order/loan lifecycle, and regulatory compliance, taking each one live from scratch. Later added gold loan as a new lending product line within ONDC FS.

Account Aggregator Ecosystem

Designed RESTful APIs for the RBI-regulated AA framework — enabling consent-based financial data sharing across FIPs and FIUs for PFM tools.

AA FrameworkRBI RegulationsConsent FlowFIP/FIU

Personal Finance Management

Built PFM tooling for categorisation, cashflow analysis, and financial health scoring — integrating with banking data sources via AA and direct feeds.

Bank Statement Analytics

Built an intelligent bank statement parsing engine — automated extraction and classification that improved loan approval efficiency by 90%.
