MANISH

Backend & automation developer

I build the parts your users never see: APIs, bots, scrapers, and the scheduled jobs on permanent night shift, keeping everything running. Mostly in Python, TypeScript, and Go.

cat about.md

I've been writing code since 2021. It started with scrapers, turned into Discord bots, then data tools, then the services running underneath them.

Most of what I build now is backend work and the tooling that sits under it: Discord bots that stay up, market data pipelines, a VS Code extension. Outside of that, I spend time rebuilding things that already exist, like a concurrent job queue or a TCP server from scratch, not because I need them, but because I'd rather understand how something works than just trust that it does. I'm taking on contract work alongside my computer science degree right now. If you've got something that needs building, or something that already exists and keeps breaking, I'd like to hear about it.

I'm taking on contract work alongside a computer science degree. If you have something that needs building, or something that already exists and needs to stop breaking, I'm interested.

Three things I get hired for.

api/

APIs & backends

REST and realtime services with authentication, a database that's modelled properly, and a deployment that survives contact with real traffic.

REST & WebSocket services
Auth, sessions, permissions
Schema design & migrations

Bots & automation

If you or your team does something by hand every week, it can almost always run itself instead. I build the thing that does it.

Discord & platform bots
Scrapers & data extraction
Scheduled jobs & pipelines

web/

Web builds

Landing pages through to full applications — front to back, hosted, documented, and handed over so you're not dependent on me to change a heading.

Selected projects.

MyRideSG

React Native · 2026

A bike ownership app for Singapore riders. Tracks servicing history, fuel logs and running costs, counts down COE, road tax and insurance renewals, and points you at trusted workshops when it is time to act. Records stay private by default and export whenever you want them.

React Native React Astro

DebugDuck

TypeScript · 2026

A VS Code extension that teaches debugging instead of handing over the answer. Four escalating levels of hints, tracks which bug types you personally get stuck on, and warns you about them before you run the code.

TypeScript VS Code API LLM

MIST-Bot

Python · 2026

A Discord bot running Minecraft server controls, music playback and community games for a live server — the always-on kind that has to keep working when nobody is watching it.

Python discord.py Docker

OHLCV-cleaner

Python · 2026

Turns raw Databento market data into analysis-ready parquet. Resolves symbology for equity ETFs, picks futures front months by volume crossover, and back-adjusts prices across contract expiries.
