What I'm looking for

I’m available for work immediately and can provide my own visa/work permit for Germany within 5-8 weeks. I’m looking to build fullstack products and browser extensions with strong engineering, testing, and AI-powered features.

I’m a Fullstack Engineer specializing in React, TypeScript, and fullstack product development, with 10+ years of project experience across web, extensions, and mobile. I currently build browser-based productivity and customer-facing platforms that combine UI, backend services, and AI assistance.

At Read Twogether, I design and develop a React/TypeScript browser extension (Plasmo, Manifest V3) while building the Next.js web platform. I architect backend services with NestJS, REST APIs, PostgreSQL, and Firebase, and integrate OpenAI, Gemini, and Claude APIs to power summarization, annotation generation, and contextual insights inside the browser. I also implement automated CI/CD and testing with Jest, reducing deployment validation effort by approximately 40%.

Earlier, as a Senior Software Engineer at Vivasoft, I built a React Native wrapper SDK bridging native iOS (Swift, Objective-C) with JavaScript, and reduced integration-related support requests by ~30%. I’ve also delivered Chrome extension features and performance gains—improving SERP data processing performance by ~50% and reducing extension memory usage by ~20%—and I lead with system design, quality, and practical delivery.
