Back to original languageAbout Geoffrey
Senior AI Software Engineer - 8 years
For B2B SaaS startups and scale-ups, I transform complex business problems into reliable and maintainable web products:
technology should serve the business, not the other way around.
At Ondorse, a KYB/KYC compliance SaaS, I transformed ad-hoc developments necessary for signing large accounts into internal no-code tools: a workflow and compliance rules editor. Result: Customer Success teams can onboard and build a client's compliance policy in **2 days instead of 2 weeks**, without relying on the tech team.
At ManyPixels, I co-founded and built from0 to $65k MRR in 1 yearan all-in-one platform: client onboarding, subscriptions, storage, chat, and designer task dispatching.
Services I offer:
🔍 Audit a product, its UX, and its architecture
I identify what limits a product's value: UX friction, overly complex journeys, product debt, fragile architecture, performance, security, or maintainability issues. I transform this audit into a clear action plan: what to fix, in what order, and why.
🚀 Take a feature or product from 0 to production
I take full ownership of a subject: customer problem, scoping, trade-offs, architecture, development, and deployment.
🔧 Take over and stabilize "code-vibe" applications
I take over your prototypes built with Cursor, Lovable, v0, Bolt and turn them into maintainable applications: clear architecture, development standards, typing, security, error handling, and managed technical debt.

Preferred Stack: React, Next.js, TypeScript, Node.js, Python/FastAPI, GraphQL, PostgreSQL, AWS, Docker, Supabase.
🧭 AI-assisted, human governance
AI as a daily assistant, not a pilot: I retain responsibility for technical choices, product quality, and security.
