// About
Hey there! I'm Komeil, a Senior Frontend Developer with 8+ years of experience in software development, specializing in building scalable, maintainable, and high-quality web applications.
My core expertise is TypeScript, React, Next.js, and modern frontend architecture. I have extensive experience designing frontend architectures, component systems, design systems, and complex data-driven interfaces, with a strong focus on performance, accessibility, automated testing, and developer experience.
I work across the modern frontend ecosystem, including React Server Components, SSR/SSG/ISR, micro frontends, Tailwind CSS, Radix UI, Zustand, React Query, Zod, and Storybook. I have strong experience with automated testing using Jest, Vitest, Cypress, Playwright, and React Testing Library. Beyond the frontend, I'm comfortable working with Node.js, REST and GraphQL APIs, SQL, BigQuery, Segment, AWS, Google Cloud, and modern build and delivery tooling such as Vite, Turborepo, Docker, GitHub Actions, and Vercel.
Throughout my career, I've worked on large-scale platform migrations, design systems, analytics products, planning tools, and AI-enabled workflows. I'm comfortable working across the full development lifecycle - from understanding business requirements and defining technical solutions to architecture, implementation, testing, deployment, and continuous improvement.
I'm particularly interested in solving complex frontend problems, improving application performance, simplifying architecture, and building systems that scale with both the product and the engineering team. I enjoy working on technically challenging products where strong engineering practices and a deep understanding of user experience come together to create better software.

komeil@amsterdam:~$ ls -la ~/projects
// Open source & side projects
Two of these exist because job hunting as an Iranian engineer is harder than it should be.
visa-sponsors-companies-for-iranians
★ 1,555A crowdsourced list of companies that have hired at least one Iranian, so the next person does not have to guess who sponsors. My most-starred repo by a wide margin.
sudoku-core
★ 110A zero-dependency TypeScript engine that generates, solves, and analyses Sudoku - step by step or all at once, with human-style solving strategies and difficulty grading.
companies-with-remote-positions
★ 494The remote-first companion list: companies hiring Iranian engineers remotely, maintained with the community.
sudoku.best
The playable front end for sudoku-core: Next.js and PostgreSQL, daily puzzles, and a hint system that explains the reasoning instead of just filling the cell.
data-structures-and-algorithms
Classic data structures and algorithms implemented in TypeScript, written while preparing for interviews and kept as a reference.
