About

Professional summary

I am a versatile full-stack engineer and AI product builder with more than 20 years of experience spanning web development, embedded systems, enterprise software, and AI-powered applications.

I build software products end to end, from system architecture and backend implementation to frontend interfaces, deployment, security, automation, and monetization. My core stack includes Python, Flask, JavaScript, React, Next.js, Node.js, SQL and NoSQL databases, Docker, and cloud deployment platforms.

I am currently building and marketing AI SaaS products, including a virtual try-on application with custom pipelines for prompt generation, image inpainting, segmentation, and photorealistic transformations. I also develop AI-powered applications for data extraction, summarization, and conversational interfaces.

My background includes senior enterprise engineering, hundreds of freelance software and hardware projects, and academic teaching and research. I have delivered desktop applications, web platforms, e-commerce systems, web scraping solutions, embedded firmware, and custom electronic products.

I bring independent leadership, strong problem-solving skills, client communication, mentoring experience, and a hands-on approach to shipping reliable products. I am passionate about innovation, continuous learning, and turning complex technical requirements into practical solutions.
