With insider Supabase knowledge, I help you make the right decisions for ensuring you get the best out of the stack along with security and performance - beyond just the database.
I'm not your usual freelancer. I don't want to spend as much time as possible; I deliver solutions. Working with me feels like a hoverboard, not like a surprise bag. I educate in-person and with documentation in a mentorship way.
I consult with 25 years of experience in web development and coding craftsmanship. Precision solutions and thorough research are my standard. In times of AI, making the right decisions upfront is essential.

Choosing the wrong architecture is very costly. My clients don't have that issue.
No matter if you want to create a realtime carsharing service, the next big AI unicorn, highly secure medical systems or simply a sleep tracker - architecting secure and scalable applications of any size is what I'm really really good at. Like, really.
Whether you experience performance issues or want to save costs by avoiding them: Planning to scale from a few hundred users to 100k users? I got you. Billions of rows in your database? No problem.
I not only help you optimize for it but actually help to bulletproof it; facts-based with load testing.
Security is a must - for your customers and to save you from expensive, unnecessary lawsuits. From exposed RPCs, Prompt injection, RLS failures and Webhook security to the detection of chained attacks: With my audit, you and your customers can sleep well at night.
Eliminate critical exploits, prevent data breaches avoid data loss, customer loss and expensive 0-day fixes.
We can work full-service agency mode from zero to final delivery. Not just web apps: I've built apps that are used in operating rooms for surgery.
After a clear briefing, I manage all the work related to it - from accessible UX to a secure backend and you sit back and relax.
What that means:I will build and deliver your high quality, business-targeted web or native (iOS / Android) app with a promised schedule including a high-end overview of exact deliverables.
What it also means:I'm not hireable as an hourly freelancer for working off generic tickets of the backlog.
My mentorings and trainings are a service for highly technical people who want to go the fast route instead of spending weeks figuring out the best ways of solving Supabase-related questions.
The quality and efficiency of both the mentoring and training is primed by an initial free briefing call.
Team Training: Hypereffective pre-planned Supabase / architecture training for up 10 people. Starting at 4999$.
Mentoring: Your issues and questions are resolved within 1-2 hours of instant technical mentoring. 699$ per hour including post-session summary (you're not left alone if we hit the time limit).
I've worked for Universities, FinTech, MedTech, Automotive Corporate, Agencies, City Councils, Streaming companies, AI startups, KYC providers and many more.
Besides my technical expertise built over the course of 25 years, I’ve been a corporate Team Lead with special leadership trainings guiding technical and personal advancement. Openness, transparency and friendliness are key drivers of my exchange.
I value clear and concise communication which is why, before I begin to work, I will clarify your needs and ask highly specific questions challenging your goals. You’ll be invited to my Slack channel where we can reach each other quickly and do video calls for more complex discussions.
I am able to adapt to different timezones, my usual timezone is CET. If the availability allows, we can go from call to execution in less than 48 hours, 24 hours in urgent cases (e.g. security incident).
For custom solutions and database optimization, yes. For architectural needs: No.
There is a saying "Just use Postgres" and it's for a reason. When it comes to helping you with best in-database knowledge then yes, I am your best bet as a Postgres expert, best combined with Supabase.
However: I'm a skilled Web Software Architect. Hence, I can build scalable systems for any type of requirements, if that needs to be MongoDB for a reason or a Graph database: Let's sit down and discuss it.
I've been a PHP developer for more than 10 years before I switched to Fullstack JavaScript / Typescript. I've contributed bits in Supabases Auth library, written in Go.
As an architect, I'm not a language or framework fanboy, whatever works for you and gets the business requirements resolved, is a great choice.
I work with teams that use Supabase and have whatever language, PHP, Go, Rust, Java, in their backend. As an architect, that does not matter, my consultancy services on an architectural and in-depth Supabase / database level are language and framework-independent.
