What I've Built

Production systems across the full stack — frontend experiences, backend APIs, cloud infrastructure. I've built platforms that scale, led teams that ship, and operated infrastructure that stays up. Deepest expertise on the frontend with Svelte and React.

What People Say

From People I've Worked With

"Masih was a standout engineer at Goki. During his time with us, our product team doubled revenue, and Masih was a key contributor to that result. Beyond his strong technical skills in React, TypeScript, and Node.js, he elevated the entire engineering organization — leading coding standards, running design reviews, and mentoring developers across the team. He also drove a company-wide refactoring initiative that significantly improved maintainability and development speed. I'd recommend Masih highly for any senior engineering role."

Arash Karimzadeh

Founder & CTO, Goki (backed by Hostelworld)

"Masih is a versatile, reliable senior engineer. At Thinkeo, he delivered across the full stack — Node.js backend services, React frontend, Docker containerization, and cloud infrastructure. He automated our build and release processes, which made deployments faster and more consistent for the entire team. He also mentored other engineers and contributed thoughtfully to system design decisions. I'd recommend Masih to any company looking for an engineer who truly owns what he builds."

CTO, Cobl.ai · Paris, France

"Masih was the technical backbone of Pelas during our early and growth stages. As CTO, he designed and built our multi-tenant SaaS platform from the ground up, while also hiring and leading a team of engineers. He established strong engineering practices — from CI/CD and infrastructure to code quality and architecture reviews. What sets Masih apart is his ability to combine deep technical expertise with strong leadership. I highly recommend Masih for any senior or leadership role — he brings both ownership and execution at a very high level."

"Masih was one of the most impactful engineers I worked with at Goki. He made a meaningful contribution to our growth, helped lift the standard of engineering across the team, and was someone others naturally looked to for guidance. He consistently combined strong technical ability with real ownership — building reusable component libraries, driving significant refactoring work, and delivering features with direct business impact. What stood out most was his initiative and maturity — he did not just complete tasks, he looked for ways to improve systems and raise the bar overall. I would confidently recommend him to any company looking for a strong full-stack or platform engineer."

"I feel lucky to have met Masih in my life! He was a key senior engineer at Thinkeo and someone I could always count on to deliver. It's more than precious! He owned complex features from architecture through deployment, contributed to our AI document generation pipeline, and brought our DevOps practices to a much higher standard. He doesn't just write code, NO — he thinks about the product and the business. Something no AI could do! His work had a real, measurable impact on our growth. Highly recommended for any senior or staff engineering role"

About

Who I Am

I'm a full-stack engineer with 10 years of experience building production systems end-to-end, with a particular depth on the frontend. My work spans polished, accessible UIs to backend APIs and cloud infrastructure — but Svelte and React are where I go deepest.

Most recently, I designed, built, and solo-operated a globally distributed platform — 100 servers across 20 countries, 5,000+ paying subscribers, 100K+ transactions — handling everything from frontend architecture and UI to infrastructure and incident response.

Before that, I was CTO at Pelas, a real estate SaaS platform: designed the multi-tenant architecture, built the full frontend component library, hired and led a 15-person engineering team. I also spent two years as a senior frontend engineer at Cobl (formerly Thinkeo), an AI document generation startup in Paris, where my work directly supported their first $1M fundraise.

I'm comfortable across the full stack — Svelte, React, TypeScript, Node.js, NestJS, GraphQL, PostgreSQL, Docker, AWS — and equally happy designing system architecture or heads-down writing code.

On StackOverflow, I've reached 13M+ developers and earned 11,000+ reputation — placing me in the top 1% globally, with 4 gold badges. See my profile →

Looking for my next role.

If you're building something ambitious and need an engineer who goes deep on the frontend — Svelte, React, TypeScript — while being equally comfortable owning the full stack from architecture through deployment, I'd love to talk.
