Slavik Chernenko
Founder and CEO of CimaStudio. I build SaaS, EdTech and AI products for founders and small and medium businesses.
Why CimaStudio exists
Cima means summit. I started the studio because I kept meeting founders with strong ideas who'd been let down by agencies: vague estimates, months without a working demo, and code they didn't own.
For seven years I've built web, mobile and AI products as a full-stack developer and technical lead, for founders and SMEs. On Upwork, my work has earned the Expert-Vetted badge, a 100% Job Success score and more than 18,000 hours across the teams I've led.
I lead every CimaStudio project personally, from the first conversation to launch and after, with a small team of senior collaborators for design and development.
What I work on
Industries: EdTech, HealthTech, LegalTech, research tools and enterprise SaaS.
AI: RAG pipelines and vector databases, AI agents, voice AI with ElevenLabs and Whisper, multi-model setups with OpenAI, Anthropic Claude and Google Gemini, LangChain.
Engineering: React, Next.js, Node.js, TypeScript, Python, React Native, PostgreSQL, Stripe, AWS and Cloudflare.
Compliance: GDPR-first architecture for schools and children's apps, HIPAA-aware healthcare tools, FERPA and COPPA considerations for education.
