Freelancer profile translated to English.
Back to original languageAbout Mik
With over 20 years of experience in software development, architecture, and technical leadership, I support startups, SMEs, and scale-ups in creating, auditing, and ensuring the reliability of digital products.
I specialize in MVPs, SaaS, and rapid prototypes – using AI, no-code, agencies, freelancers, or internal teams – when it's time to transition from a product that "works" to a reliable, secure, and production-ready product.
What I Do
- Technical audit before launch: architecture, security, authentication, payments, data, performance, technical debt.
- MVP / SaaS reliability: refactoring, testing, deployment, documentation, prioritization.
- Part-time CTO: product vision, technical roadmap, decision-making, team support.
- Hands-on development: web applications, mobile apps, SaaS, internal tools, MVPs, and POCs.
- Applied AI: LLMs, AI agents, automation, RAG, AI-first workflows.
- Architecture & DevOps: CI/CD, cloud, observability, scalability, security.
My Approach
Senior, pragmatic, and product-oriented: I connect technical choices to business objectives, without unnecessary over-engineering. I can audit, scope, develop, or turn around complex situations.
Recent Examples
- Audit of projects built rapidly with AI tools.
- Development of Opla, an open-source platform for local AI assistants.
- Cryptography platform with Rust, React, FastAPI, WebAssembly, and P2P.
- Hands-on CTO at Storyfox, a large-scale video SaaS.
- AI-first development workflows with AI agents, testing, and documentation.
Do you have a prototype, an MVP, or a SaaS that needs to reach the next level? I can help you identify what's ready, what needs to be secured, and the priority next steps.
