Oleksiy K.
CTO as a Service | MVP Development, Bots & Automation, Payment Systems
I build products, not just features. Eight years of shipping — from Telegram bots to fintech platforms to full-scale membership systems with teams of 18. What I do best: → CTO as a Service — fractional technical leadership for startups. Architecture, team setup, CI/CD, sprint management, delivery. → MVP Development — your idea to production in 8-12 weeks. Payments, auth, admin panels, deployment — the full stack, done right. → Bots & Automation — Telegram, Discord, WhatsApp. If your team does it manually, I'll automate it. → Payment Systems — Stripe, crypto, subscription billing, marketplace payouts. Built from scratch, not duct-taped. → Real Estate Tech — CRM, listings, property management for EU agencies. → DevOps — Docker, CI/CD, monitoring, infrastructure that doesn't need prayer. Stack: Python, TypeScript, React, Next.js, Node.js, PostgreSQL, Docker, AWS. BSc Computer Science, Igor Sikorsky Kyiv Polytechnic Institute. I take 2-3 clients at a time. Every project gets deep focus.
