Building software.
Always asking why.

I'm Pratik, a software engineer in Mumbai. I build backend systems, explore what makes them tick, and write down the useful bits.

About

From classrooms to capital markets.

I started building education software in 2014. Since then, I’ve worked on forest-rights applications, digital lending, and trading platforms—moving from writing individual features to leading teams and upgrading complex systems.

Java and Spring Boot are my main tools, with Go, React, and Vue also in my toolkit.

    Faster merchant screening

    Lending at scale

    Senior Consultant – Developer · September 2021–July 2024 · Mumbai

    MKCL

    Public services, real deadlines

    Senior Software Engineer · October 2018–September 2021 · Mumbai

    Building MP Vanmitra, a platform for forest-rights applications in Madhya Pradesh, took me from solo contributor to team lead. A later project brought a very different challenge: a one-week deadline.

    • The platform supported nearly 200,000 individual and 28,000 community forest-rights titles.
    • Led part of a nine-person team that delivered a COVID-19 surveillance portal for Pune in one week.

    Behind the scenes of online exams

    Software Engineer · October 2016–October 2018 · Mumbai

    Online exams leave a trail of screenshots and recordings. For MKCL ERA, I built the tools to collect, package, and archive them.

    • Built ERA Helper in Go to collect screenshots and recordings.
    • Built ERA Archiver to package recordings into 1 GB files and store them in AWS S3 Deep Archive.
