About Ugo

For the past year, I have been building my own products from scratch. I designed, developed, launched and monetized 10 web apps solo, including InstantGradient, Mokkit and OpenPreview. Every step was mine: product decisions, design, code, payments, launch and marketing.

Before that, I spent six years as a Python developer, building back-ends, AI applications and data pipelines with companies in several countries.

What I offer:

Building the first version of your product, end to end. You bring an idea, I bring it to life: landing page, full stack web app, payments, deployment, analytics. I work in fixed-scope MVP sprints, so you know the price and the timeline before we start.

I am the right person if you are an early-stage founder or a small team that needs a working v1 in a few weeks. I can also bring value to medium size teams as an Python, Backend, or AI engineer.

Based near Strasbourg and Karlsruhe, working remotely or on-site in the region. I work in English and French.

Experience

    Solo Founder
    October 2025 - Today (9 months)
    Bühl, Germany
    Building, launching and monetizing my own web products from idea to revenue. In the last year, I designed, developed and shipped 10 web apps solo, owning every step from product decisions to marketing.

    🚀 Product & Building
    🔸 Designed, developed, launched and monetized 10 web apps solo, including InstantGradient (mesh gradient generator), Mokkit (device and screenshot mockup tool) and OpenPreview (dynamic OpenGraph image generator)
    🔸 Took each product from a vague idea to a live, paying product, scoping features to ship a v1 in a few days
    🔸 Owned product decisions end to end: what to build, what to cut, and what to build next based on user feedback and data

    🛠 Full Stack Development
    🔸 Built full stack web applications front to back (Next.js, React, TypeScript)
    🔸 Integrated payments and monetization with Stripe (subscriptions, one-time passes, credits)
    🔸 Deployment, hosting and monitoring (Vercel, Supabase, MongoDB, VPS, Docker Compose)

    📈 Growth & Monetization
    🔸 Handled landing pages, SEO, content, social media and paid ad campaigns
    🔸 Set up pricing and packaging, with most products finding paying customers within weeks of launch
    🔸 Learned firsthand that building fast is only half the job: distribution, pricing and positioning decide the rest

    👨‍💼 Founder Life
    🔸 Sole owner of every decision, from code to branding to customer support
    🔸 Self-taught across design, marketing and monetization to ship complete products alone
    🔸 Now putting this end-to-end experience at the service of early-stage founders and startups who need their first version built fast
