Senior Full-Stack Engineer · Browser Extension Developer · Solutions Architect

I build scalable web platforms, high-performance browser extensions, and SaaS systems that transform complex workflows into efficient products.

With 10+ years of professional experience, I specialize in delivering production-ready software with a strong emphasis on architecture quality, extensibility, and business value.

• Full-stack web application development
• Browser extension architecture (Chrome, Edge, Firefox)
• SaaS platforms & subscription systems
• Workflow automation & productivity tools
• System design & legacy modernization

I design and ship production-grade browser extensions, ranging from lightweight productivity tools to complex, state-driven extensions integrated with backend services.

Capabilities include:

• Chrome Extension Manifest V3
• Content scripts, background/service workers
• DOM manipulation & page automation
• Secure messaging between extension and backend
• Authentication, licensing & subscription enforcement
• Cross-browser compatibility (Chrome / Edge / Firefox)
• Performance optimization & permission hardening

Typical use cases:

• Productivity & automation tools
• Web data processing and UI augmentation
• Privacy, security, and content-control extensions
• SaaS-integrated extensions with user accounts

• Next.js, React, TypeScript
• Tailwind CSS
• Vite, Webpack
• Electron (desktop apps)

• Chrome Extension APIs (MV3)
• WebExtensions API
• React-based extension UIs
• Extension build pipelines (Vite / Webpack)
• Store-ready packaging & publishing

• Node.js, NestJS
• Java (Spring Boot)
• Python (FastAPI)
• REST APIs, GraphQL
• Auth, licensing & billing systems

• PostgreSQL, MySQL
• Redis
• MongoDB
• Kafka, RabbitMQ

• Docker, Kubernetes
• AWS (EC2, S3, RDS, CloudFront)
• Nginx
• CI/CD (GitHub Actions)
• Linux, Bash

• Git & GitHub
• Postman
• Figma
• AI-assisted development workflows

• Browser extensions with real business logic, not just UI scripts
• SaaS platforms with subscriptions, licensing, and user management
• Automation tools that replace repetitive manual workflows
• Internal dashboards & admin systems
• System refactors from legacy codebases to modern architectures

• Extension-first architecture

  Clean separation between UI, background logic, and backend services.

• Scalable SaaS integration

  Extensions designed to evolve alongside backend systems.

• Security & compliance

  Principle of least privilege, secure message passing, and data isolation.

• High delivery efficiency

  AI-assisted workflows for rapid prototyping and reliable production releases.

• Production mindset

  Code is clean, documented, and designed for long-term ownership.

• Custom solutions

  Built around real user behavior and measurable outcomes.

• Technical consulting

  Architecture reviews, extension audits, and performance optimization.

If you’re building:

• a browser extension product
• a SaaS + extension hybrid
• or a modern web platform

I’m open to collaboration and technical discussions.
