What I'm looking for

I’m looking for a TypeScript-first team where I can own frontend architecture, improve performance and reliability with observability, and deliver full-stack features—from secure APIs to production-ready user experiences.

I’m a Senior full-stack engineer with 6+ years building TypeScript-first web platforms and production APIs, blending frontend architecture depth with strong systems fundamentals: algorithms, data flow, asynchronous runtime behavior, and typed-language design in TypeScript/C#. I’m also onboarding-ready for international B2B setups (Deel or direct invoicing).

At Portal.ir, I accelerated delivery throughput by introducing feature-oriented widget architecture and reusable typed modules across a large Next.js codebase. I reduced initial JavaScript payload by ~50% using lazy loading, code-splitting, and dependency analysis, and improved runtime responsiveness with virtualization-aware rendering and predictable data-flow hooks. I strengthened reliability and observability by integrating Sentry and GA4 with typed client/server boundaries in a React 19 + Next 16 stack.
