Building the Future of Your Tech
Hands-On CTO & Full-Stack Developer
10+ years building, scaling, and operating SaaS and AI-enabled platforms. I combine deep technical execution with engineering leadership — from architecture and cloud infrastructure to hands-on frontend and backend development.
How I Help
End-to-end technical expertise — from hands-on engineering to C-suite strategy — for startups and enterprises building ambitious products.
Full-Stack Development
Ship production-ready web applications with React, Next.js, TypeScript, and Node.js. From MVP to enterprise scale — clean architecture, tested code, and rapid delivery that keeps your product ahead of the market.
Fractional CTO
Senior technical leadership without the full-time overhead. Architecture decisions, engineering team management, and technology strategy that scales — embedded in your company, invested in your outcomes.
AI & Intelligent Systems
Turn AI from buzzword to business advantage. Custom RAG pipelines, LLM integration, and intelligent automation designed for production — not just demos. From proof of concept to revenue-generating AI products.
Cloud Architecture & DevOps
Scalable, secure infrastructure on AWS and Azure. Containerized deployments, automated CI/CD, and monitoring that lets your team ship with confidence. Cut cloud costs while improving reliability.
Technical Auditing
Uncover hidden risks before they become costly problems. Comprehensive code reviews, security assessments, and infrastructure analysis that give you a clear action plan for improving performance, security, and maintainability.
Technical Consulting
Strategic technology guidance from someone who’s built and scaled platforms firsthand. Make confident decisions on architecture, vendor selection, build-vs-buy tradeoffs, and technical hiring.
Selected Work
Real projects, real impact. From AI platforms to ESG enterprise tools.
