AI-powered full-stack product engineer with 13+ years of experience building SaaS, e-commerce, fintech, IoT, education, and security products. Individual contributor, owning product feature delivery end-to-end - driving architecture decisions, mentoring juniors. I help companies turn business requirements into production-ready software: from MVPs that need to launch fast to enterprise systems that need to scale, stay secure, and keep shipping under pressure. Across 30+ delivered projects, I’ve built and extended platforms used by millions of users, contributed to SOX-compliant systems, shipped real-time and high-load applications, and led delivery across complex product environments. My work has supported measurable business outcomes, including 7% conversion growth, faster go-to-market, lower maintenance overhead, and reliable scaling in production. I work across the full stack, with a strong focus on architecture, execution, and business alignment. That includes React, Next.js, Node.js, Ruby on Rails, NestJS, AWS, distributed systems, payments, integrations, and cloud infrastructure. What clients get from working with me: - Clear technical decisions, not endless options - Strong ownership and high agency - Clean, maintainable code with production standards from day one - Fast adaptation to new tools, changing scope, and delivery pressure - A bias for experimentation, iteration, and measurable results What I deliver: - Product and system consulting - Custom web application development - SaaS platforms and multi-tenant systems - API design and third-party integrations - E-commerce platforms and payment flows - Performance optimization and scaling - AWS infrastructure and architecture - UX/UI improvements that support engagement and conversion If you’re looking for someone who understands both the technical and business sides, and can turn complexity into working software, let’s talk.

Are your employees spending more time fighting spreadsheets, copy-pasting data, and wrestling with off-the-shelf software than actually doing their jobs? When standard tools stop fitting your unique workflow, your business hits a ceiling. You start losing information, making mistakes, and wasting money on manual work. I build custom web applications, internal portals, and CRMs that adapt to your business — not the other way around. I don't just write code; I digitize your daily operations to eliminate chaos and help you scale without constantly hiring more managers. I know exactly why software projects fail: developers rarely try to understand the actual business. I take a different approach. For instance, when I built a custom CRM for a translation agency, I didn't just take a list of features. I dug into their daily bottlenecks, automated their task distribution, and delivered a system that saved them hundreds of hours. If you are tired of technical headaches and need a reliable system that actually works for your team, let's talk. Send me a brief message about the biggest bottleneck in your current process, and I'll let you know how we can fix it.
