Janni Hares is the co-founder of decivo and bridges classical software architecture with modern AI orchestration. For over a decade he has built digital products — from prototypes for early-stage startups to robust systems for established mid-market companies.
At decivo he leads technical architecture and the AI-driven development workflow: research, UX validation, prototyping and code are interlocked so costly wrong turns become visible early — not in the production system.
His articles share practical knowledge on MVP development, AI workflows, and the question of when fast iteration actually pays off — and when clarity before code is the cheaper path.
