Product Engineering
For founders and teams who need a senior engineer who can own a feature or a product end to end, not just implement a ticket.
Full-Stack Engineer · SaaS Founder
I build products people actually pay for.
I build production software used by real customers. I'm a full-time Software Engineer at a German software company, and outside of work I've built SaaS products with paying customers across three continents.
- 400+ registered users
- Paying customers across Europe, North America, and Asia
- 100% organic SEO growth
- 6+ years shipping production software

How I can help
Two ways to work together, described in business outcomes, not a laundry list of frameworks.
SaaS & Internal Tools
For businesses that need software built from scratch: dashboards, APIs, customer portals, workflow tools, with the same care I put into my own products.
Selected work
Products designed for real use
Two featured projects. Each began with a concrete problem and shipped with a measurable business outcome.
Formgrid
- Problem
- Businesses needed form backends without vendor lock-in, opaque data practices, or building a server for every site, and once submissions came in, no way to track or follow up without a separate CRM.
- Solution
- An open-source form backend and no-code builder with a built-in lead pipeline and an AI Smart Inbox that automatically categorizes, prioritizes, and summarizes every submission.
- Business outcome
- Grew to 400+ users with paying customers across multiple continents through organic SEO. Open-sourced with 46 GitHub stars and processes over 1,000 submissions each month.
- React
- TypeScript
- Node.js
- Express
- Prisma
Sheetrocket
- Problem
- Teams needed live spreadsheet data in their products, without backends, Cloud credentials, or fighting API rate limits.
- Solution
- A micro-SaaS that turns any Google Sheet into a documented JSON API, with dashboards, caching, and usage controls.
- Business outcome
- Grew to 200+ active users and validated product market fit with no external funding.
- React
- TypeScript
- Next.js
- Node.js
- MySQL
- Prisma
- Redis
How I work
A calm path from idea to launch
Five clear stages. You always know where we are, and what comes next.
- 01
Discovery
Clarify goals, users, constraints, and success metrics, so we build the right thing first.
- 02
Planning
Architecture, scope, and milestones. A clear plan before a single feature ships.
- 03
Development
Iterative delivery with working software every sprint. Transparent progress, no black boxes.
- 04
Launch
Hardening, documentation, and handoff so the product lands cleanly in production.
- 05
Support
Optional partnership after launch: fixes, iteration, and guidance as usage grows.
Experience
Impact over job titles
Roles framed by the problem solved and the business outcome, not a stack dump.
Senior Frontend Engineer
Green Vision Solutions GmbH · Germany · Remote
2024 - Present
- Problem solved
- GreenHub's carbon reporting UI needed higher accuracy and reliability for the audits hundreds of companies rely on.
- Business outcome
- Refactored the frontend architecture with React and Redux Toolkit to separate forms from views, rebuilt the KPI dashboard's data formatting and calculation logic for audit-grade accuracy, and built a Jest test suite to catch regressions before release. Reduced redundant API calls and prevented empty resource creation, improving server reliability, while more accurate KPI dashboards and faster QA cycles contributed to customer adoption and revenue growth over the past 2 years, as the sole frontend engineer on the platform.

About
Built from Ghana. Used everywhere.
I've spent six years shipping production software, currently as the sole frontend engineer on a carbon reporting platform used across Germany and Europe. Alongside that, I've spent the past year building Formgrid on my own, at night, from writing the backend to writing the blog posts that got it found. A lawyer in Brazil found it through Perplexity AI. An event manager in San Diego upgraded the same day she signed up. Neither of them cared where it was built. They cared that it worked.
That's the standard I hold every project to: does it actually solve the problem, for the person who has it.
