Technical & Product Audit SwiftLogist — MVP Diagnosis and RoadmapTRANSPORTATIONMay 2026 - May 2026Technical & Product Audit for SwiftLogist — MVP Diagnosis and Roadmap€50k invested over 2 years with an external agency, without a usable platform at the end: previous team gone, technical dependencies locked with the provider, a founder blocked by their MVP.I conducted acomprehensive auditacross 7 dimensions (Symfony back-end, React front-end, database, DevOps, security, code quality, functional coverage), mapping 89 features. Verdict: 30-40% of the code recoverable, core business to be rebuilt, dependency on the agency to be broken.The client receivedclear deliverables:detailed audit report, prioritized 3-sprint roadmap (sovereignty → stabilization → monetization), clear MVP decisions, and a costed plan within a defined budget.The founder regained control of their platform and has an operational plan to deliver a marketable beta in 2 months. Development mission started immediately after. - ASTPrepCTO as a ServiceEDUCATION AND E-LEARNINGOctober 2025 - May 2026 (7 months)An e-learning platform that existed. But couldn't grow anymore.ASTPrep, a leading platform for AST entrance exam preparation, had a functional base: courses, exercises, subscriptions. It worked. But the architecture couldn't keep up: limited performance, blocked features, too slow evolutions.The founders needed a technical partner capable of taking charge of the product — not just a developer to execute tickets.My mission as an outsourced CTO: take over technical leadership, modernize the stack, deliver key features, and lay a solid foundation for scaling by structuring a tech team.🔧 What I built and managed:→ Complete architecture overhaul: Symfony 7.1, PHP 8.2+, Docker/FrankenPHP, caching, modern frontend.→ High-performance video streaming, timed mock exams with automatic scoring, guided progress tracking, spaced repetition flashcards.→ Structured monetization: Stripe subscriptions, conditional access.→ Business automations: asynchronous workflows, CRM sync, notifications, transactional emails.→ Comprehensive admin panel, Sentry monitoring, tool-assisted code quality.✅ Result: a stable, high-performance platform, adopted by students — and most importantly, capable of evolving without breaking everything with each new requirement.💼 Have a SaaS that's running but plateauing?No in-house CTO, a hindering stack, features waiting too long?This is exactly what I do: I take on the role of an outsourced CTO, I structure, I deliver, and I evolve your product — with you, over time.
