Md Shahriar Rashid · Senior Software Engineer
I make slow systems fast and fragile systems boring.
I'm Shahriar, a senior software engineer at Enosis Solutions in Dhaka. Three promotions in three years, mostly earned by profiling Node.js services, locking down cloud infrastructure, and refactoring the code everyone else avoided. Open to new roles, remote or on-site, and freelance work.

Experience
Growing into bigger challenges each year.
All at Enosis Solutions, a software services firm in Dhaka. I joined in March 2023 and have been promoted every year since.
Senior Software Engineer II

- Migrated two frontend apps from Create React App to Vite, cutting build times 30–40%.
Software Engineer I
Mar 2023 – Feb 2024
- Brought report generation down from O(N³) to O(N²) and added multi-model support.

About
The unglamorous parts, done well.
I got here through competitive programming: four years of contests at IIUC, 1,200+ solved problems, and a habit of asking what code costs, not just what it does. Somewhere along the way that turned into a career of making production systems faster and harder to break.
The work I'm proudest of rarely demos well. Moving auth off connection strings. An O(N³) report that became O(N²). Build pipelines that stopped wasting everyone's morning. If your team cares about that kind of work, we'll get along.
