What I'm looking for

I’m looking for a remote/async team where I can lead frontend architecture with React/Next.js, monorepo design systems, and performance optimization (Core Web Vitals). I want ownership from MVP to production, plus mentoring and solid engineering culture.

I’m a Senior Frontend Engineer with 7+ years building enterprise React, Next.js, and TypeScript platforms across SaaS, ERP, fintech, and e-commerce. I lead frontend architecture end-to-end—from MVP to full-scale production—specializing in monorepo patterns, design systems, performance optimization, and testing.

Most recently, I led frontend engineering for an ERP/CRM platform serving 100k+ customers in a 7-person Agile team, established GitHub Actions CI/CD pipelines, and cut average feature lead time from 5 days to 3. I also built a dynamic JSON-to-UI rendering engine that auto-generated 100+ configuration-driven forms and interfaces, saving roughly 30 development hours per release cycle.

Previously at Wallex, I architected a centralized Nx monorepo and a Storybook-documented design system adopted across 12 internal products on a fintech platform serving 6M+ users. I shipped an MVP in under 7 weeks, reduced production regression incidents by about 30% using E2E (Cypress, Playwright) and unit (Jest, Vitest) suites, and refactored a legacy Redux state layer to cut unnecessary re-renders by 60% while improving Core Web Vitals.

I’ve also delivered production-grade frontend work remotely for U.S. clients, built core modules with 80%+ test coverage, and introduced modern component architecture adopted across 3 squads. Alongside engineering, I mentor and teach—taught React/Next.js/TypeScript/Node.js to 1000+ students through Shiraz University Innovation Center and Maktab-e-Sharif bootcamps (2020–2024).
