Md Hishaam Akhtar

Bi, and proud of it.

I build backend systems at Groww, and I co-founded Harf Studios to make Urdu fun for everyone.

About

I’m an engineer who loves to build: not just systems that scale, but ideas that question norms and tools that quietly empower.

What I care about most is where code meets compassion. I’m drawn to how technology shapes the way people think and feel, how it might support mental health, and how it can make learning fairer for everyone.

Lately a lot of that has gone into Urdu. I found it through Nusrat and the Sabris and never quite left, and Harf is my way of holding that door open for other people.

Above all, I believe engineering should be inclusive by design: thoughtful, humane, and built to serve those most often left out.

Work

Harf Studios حرف

  • Co-founder 2026 – now

Harf means letter, the one every word starts with. Vaniya Adeeb and I started it in 2026 to make Urdu fun for everyone, and to give people a better way in than a textbook or a strict class.

  • An Instagram page that about seventy thousand people follow, with carousels on Urdu words, poetry, films and more.
  • Song lyrics read properly, line by line, in Urdu, Devanagari and Roman script.
  • Our first book, Dars, Volume One: Urdu from the letters up.
  • I look after the engineering, from the website to the shop that ships the book.

Groww

  • Software Development Engineer 2 Apr 2025 – now
  • Software Development Engineer 1 Jun 2023 – Apr 2025
  • Software Development Intern Jan 2022 – Jun 2023

I work on the Customer Engagement Platform, which Groww’s teams use to reach users over email, push, WhatsApp, the feed, stories and Journeys. I own several parts of it end to end, across generic, personalised and journey campaigns.

  • Led the design of a multi-tenant architecture, so teams and business lines run their own campaigns on shared, governed building blocks.
  • Cut the Journeys micro-batch window from an hour to five minutes.
  • Made personalised campaigns cheaper by deduplicating CDP attributes over Iceberg, removing redundant Spark joins, and tuned Apache Pinot to use far less memory and CPU.
  • Moved segments and channel analytics from batch to real time, with frequency capping, Trino failover and indexed event search.
  • Built real-time stock alerts for Feed and Stories, the Autochartist integration, and portfolio-aware MF Prime recommendations that go out the moment a user acts.
  • Earlier, worked on an insurance product that was never released, including its payment workflows on Temporal.

Trademarkia

  • Software Consultant Feb 2021 – May 2021

A short consulting stint on legal data: a pipeline and search API for trademarks, an asynchronous scraper for geolocation data, and alerts for legal events over email, SMS and push.

Projects

  • Hatch

    An email scheduler that doesn’t lose mail

    Schedule an email for an hour from now or years from now, with at-least-once delivery. A timer-wheel scheduler sharded across replicas drops each email onto Kafka when it falls due. Failed sends climb three retry tiers, and a reconciliation job recovers anything a crash left behind.

  • Hermes

    Live quizzes, run like a broadcast

    A real-time quiz and polling platform. Organisers build quizzes and run sessions question by question; players join with a code, and the lobby, answers and results update live over WebSockets.

  • Nexia

    A digital slambook for your people

    Keep the details about friends and family you’d otherwise forget, like favourite songs, food quirks and old memories, then ask things like “who hates mushrooms?”. The assistant answers from your own notes, and asks before it changes anything.

  • Stochastick

    Flappy Bird, played on real stock charts

    Pick an NSE stock and a timeframe, and its real price history becomes the level: every candle is a pair of pipes. Crash, and it tells you the date and price that got you. Fully static, with the market data shipped alongside.

  • Iris

    The shortest path between two Wikipedia pages

    Give it two pages, say Banana and Shah Rukh Khan, and it finds the trail of links between them. A bidirectional search meets in the middle, Redis holds the state, and the path is drawn as a graph you can drag around.

  • Jury Duty

    Many hands, one dataset, no collisions

    A labelling engine for teams annotating one dataset with several raters. It hands out items without collisions and stores every label in Postgres, ready for inter-rater reliability and bias analysis.

  • java2go

    Go, explained in Java

    A guide to Go for people who already know Java. Thirty-one sections, each starting from the Java you know, with idiomatic Go beside it and why Go made a different choice.

  • Sociocredz

    Give away the points you’ll never spend

    Donate unused loyalty points to NGOs. Built in 24 hours at Access Denied 2.0, where it won.

  • Keats

    A reading club in your pocket

    An Android app for reading together: clubs, shared annotations, and discussions pinned to the page you’re on.

Research

Real-Time Captioning of Sign Language Gestures in Video Meetings

With Sharanya Mukherjee and Dr. R. Kannadasan · Presented at ICCMDE 2021 · arXiv:2507.14543

A browser extension that turns American Sign Language into live captions everyone in a video call can read. A local model, fine-tuned from MobileNetV2 on the WLASL dataset, streams its guesses over a WebSocket to the extension, which draws the subtitles. It reached 63% word-level accuracy with an ordinary webcam: no gloves, no depth sensor.

Email is the best way to reach me. I’m always happy to talk about backend systems, Urdu, or something you’re building for the people who usually get left out.
