Curious bydefault.
I'm Rohan. I build software, and I'm happiest when what I make gets used by someone who isn't me.
I pick up a tool by making something real with it, so most of what I know came from products I actually shipped.
I like problems with clear users: a town with broken streetlights, a person trying to understand their bloodwork, someone drowning in AI tabs.
Below is what I work with, and what I use each tool for.
Languages what I write
Python
Scripts, automation and quick problem-solving.
Java
Object-oriented fundamentals and structured programs.
JavaScript
What most of my products run on, from Flowzco to Cryvanta.
TypeScript
Typed code for the bigger, riskier builds like Nexus Wallet.
HTML
Clean, accessible structure for every page I ship.
CSS
Layout, motion and the details that make a site feel finished.
Frameworks & platforms what I build on
React
Interfaces for TOG Fix and Nexus Wallet.
Ruby on Rails
Web apps with a real backend, built the conventional way.
Laravel
PHP framework for fast, well-structured back ends.
Supabase
Auth, database and APIs behind Flowzco and TOG Fix.
PostgreSQL
Relational data modelled properly before the first screen.
Cloudflare
Hosting, edge and storage, including this site.
Postman
Designing, testing and debugging APIs before a single screen depends on them.
Railway
Deploying and running back ends without babysitting servers.
Chrome extensions
Browser APIs and tools that live in the toolbar.
Everyday tools how I get things done
GitHub
Where my code lives. Find it all at github.com/rohancoding5.
Excel
Advanced formulas, tables and analysis.
Access
Databases and forms that streamline how a team works.
Google Workspace
Docs, Sheets and Drive for everything collaborative.
