Über Sergei

I'm Sergei Fedotov, a CTO/CPO with 20+ years of experience launching tech products — from idea to scale. I specialize in MVPs, SaaS platforms, AI automation, and marketplace solutions.

I've led the development of:
-Express Market– a fast-growing multi-category marketplace for local artisans and farmers
-Milolepo– Serbia’s largest handmade marketplace (2,000+ sellers)
-B2BForce– a SaaS platform for automated LinkedIn sales with integrated AI
-RestoGrand– a loyalty and online ordering platform for restaurant chains
-MyKuvar– a hyperlocal food delivery service connecting home chefs and customers
-SkillFactory– an AI-based learning assistant with real-time feedback
-Thermopack Digital Twin– a manufacturing optimization engine using simulation & algorithmic planning

My stack includes PHP, Laravel, Java, Node.js, Python, PostgreSQL, and AI tools like OpenAI/GPT. I deliver production-ready systems with clean architecture, deep API integrations, and smart UX — from Telegram bots to automated content pipelines and localization engines.

Let’s build something powerful and scalable — together.

Projekt- und Berufserfahrung

  • Mars
    CTO / CPO
    Juli 2025 - Juli 2025
    We built a digital simulation system for production lines that lets managers make decisions before investing in equipment or staff. The model simulates each operation, finds bottlenecks, calculates optimal utilization for people and machines, and proposes scenarios to increase output and reduce unit costs. The rollout delivered up to an 18% output increase without extra investment and gave leadership solid data instead of guesswork.
