Aleksei Andreev

As a Python Backend Developer with 5 years of experience, I specialize in transforming cutting-edge AI and LLM technologies into scalable, production-ready products. My core expertise lies in architecting and building robust backend systems from the ground up, integrating complex external services, and driving tangible business outcomes-from user growth and engagement to operational efficiency. I thrive on making sophisticated AI solutions not just functional but genuinely valuable for clients and end-users.

My track record is defined by delivering measurable results. I have successfully launched a multi-agent AI assistant that processed over 100,000 requests within six months and boosted user engagement by 40% for corporate clients. I architected a marketplace platform supporting 1M+ users with 99.6% uptime and developed 13 NLP services that automated document analysis, reducing manual labor by 35% and increasing processing accuracy by 20%. I am adept at turning technical complexity into reliable performance and clear business advantages.

My focus is on engineering the infrastructure that powers next-generation applications in AI, fintech, B2B SaaS. I am driven by the challenge of building systems that are not only technically elegant but also deliver exceptional scale, resilience, and user value.
