Hi, I'm Hossain Sany

Full-Stack Software Engineer

I specialize in the React/TypeScript ecosystem and serverless database architecture. Currently focused on building scalable UI/UX and robust backend pipelines for fast paced scale ups.

01/ About Me

Hi, my name is Hossain and I'm a Full-Stack Developer focused on shipping software that holds up in production, not just in a demo. Most recently, I architected and launched an EdTech SaaS platform now serving 2,500+ active users, owning everything from schema design in Drizzle to the infrastructure it runs on.

As an independent consultant, I've spent the last few years working directly with clients and stakeholders, translating requirements into working software. I maintain a 100% Job Success Score on Upwork, backed by a history of 5-star reviews. Whether I'm orchestrating payment webhooks with Stripe or building seamless React interfaces, I prioritize the reliability and client satisfaction that professional grade software demands.

Here are some technologies I've been working with recently:

React

Typescript

PostgreSQL

Next.js

Tailwind CSS

MongoDB

Tanstack Start

Express.js

Drizzle ORM
