Fractional CTO · I audit and fix AI-built & outsourced apps
Meet Oleksii
5.00 (2)15 years running dev teams, CEO of AleannLab (~20 devs, designers, QA). Founders bring me apps built fast by outsourced teams or AI tools that have started to break. I audit the code, architecture and infra, give you a plain list of risks ranked by impact, then my team fixes what matters. Next.js, React, Node, Python, AWS, LLM integrations. Not technical? I'll tell you straight where you stand.
