Portfolio Website of Aleksei Matyunin
Hello! I’m a technical leader and project manager with over 5 years of experience in IT. I started as a full-stack developer (React, WordPress, Python) and progressed to Tech Lead and Project Manager roles. Today, my focus is on creating digital products that deliver real business value. At Saenko Group, I led a project from concept to launch: assembled a team, implemented AmoCRM, set up CI/CD, and developed an SEO content strategy. Together with copywriters, we produced over 600 articles, which helped rank the site at the top of search results and consistently generate 90+ inbound leads per month — without an advertising budget. I’ve worked on projects in fintech, e-commerce, automation, scraping, and business system integrations. I understand how to design architecture tailored to real-world tasks and constraints. I’m currently open to partnerships where I can apply my technical expertise and management mindset to build products that grow and generate profit together.
