I build the infrastructure that moves money across borders. By day, I'm engineering cloud-native payment microservices at Finastra — working on systems that banks worldwide depend on. By night, I'm chasing ideas at the intersection of fintech, AI, and data.
Specialising in banking payment systems, ISO migrations, and high-value payment infrastructure at scale.
Promoted to Senior Software Engineer, leading development of payment microservices on Global PayPlus (GPP). Owning the full lifecycle of new services — from design and development through containerisation and cloud deployment. Working across the stack with Spring Boot, Docker, and Kubernetes, with CI/CD pipelines running on Azure and Helm charts managing production releases.
Joined Finastra directly, driving the modernisation of Global PayPlus — one of the world's leading core banking payments platforms. Led development on the Fedwire ISO 20022 migration, enabling GPP to support the new global messaging standard. Built microservices at the heart of high-value payment flows, processing critical transactions for banks worldwide.
First engineering role out of college. Worked on the Finastra GPP product — a core banking payments platform — gaining deep expertise in global payment flows and clearing systems. Became a go-to engineer for payment defects and industry-driven feature changes across FED, TARGET2, CHIPS, EURO1, NPP, and NAPAS. Delivered MT-MX industry changes and earned multiple awards for impact during this time.
A mix of backend engineering, data tools, and fintech domain expertise built up over years of hands-on work.
My professional work lives in private repositories, but here are some projects from college that got me hooked on building — plus what's cooking now.
Built a data-driven decision engine for Fantasy Premier League using the official FPL API. Analysed player attributes, form, fixtures, and value metrics to generate smarter weekly team picks. The model consistently beat the weekly average points — proving data beats gut feel.
Designed and developed a full website for Aadhaar Samajik Sanstha, a Pune-based NGO, giving them their first digital presence. The site helped them reach a wider audience, communicate their mission, and connect with donors.
A Java-based elections management app built for college-scale institutions. Features a full voting workflow with separate voter and admin interfaces, real-time tally, and tamper-resistant data handling. Built with Java Swing for the UI and PostgreSQL for the backend.
Working on a few side projects in the fintech and AI space. More to share soon — watch this space or reach out if you're curious.
The things that keep my brain busy when I'm not writing code.
