Siarhei Hinkou

Full Stack Software Engineer | Individual Investor | Content Maker | Happy husband and father

Hello! I’m Siarhei Hinkou. Born in Belarus and now based in the scenic landscapes of Andorra, I am a passionate web developer and entrepreneur with a robust background in computer science. My tech journey began before I graduated in 2010, initially progressing from a junior to a senior software engineer within the consulting industry.

In 2015, I embraced a new challenge as a contractor for a renowned U.S. product company, diving into remote work well before it became the global standard. In 2021, I established my own company in Andorra to provide specialized remote B2B services.

Over the years, I've tackled a wide array of projects, from straightforward SPA to complex CRM systems and multifaceted SaaS products. I possess extensive experience with Ruby on Rails and hold a deep appreciation for JavaScript, having achieved proficiency in a variety of its frameworks and libraries.

Recently, I've been exploring the frontiers of artificial intelligence and machine learning. I am currently working on innovative projects that incorporate Retrieval-Augmented Generation (RAG) and local language models to tackle unique business challenges.

Beyond my client-focused work, I am also deeply committed to personal growth and practical application of my skills. After hours, I dedicate time to developing my own products—tools that I use in my everyday life. While many of these creations remain private, serving as internal solutions, others like the Lexigym application and Imaginkov QZ platform, are public and available for global use.

I pride myself on being a meticulous problem solver, a cooperative team player, and a perfectionist who continually seeks to optimize everything around me. My approach is simple: use the right tools for the job, adapt swiftly, and always be prepared to tackle new challenges head-on.

Thank you for visiting my site! Let’s connect and explore how we can work together to craft something truly exceptional.
