Services Across Your Growth Journey

IT Foundations & Launch

Get your company online properly from day one. I handle the essential heavy lifting: secure professional email routing, bulletproof domain configurations, corporate web presence setup, and core digital security.

Digitalization & Automation

Stop losing profit to manual toil. Modern technology is there to use it. Let me help to automate and free labor power for more productive undertakings. Digitalization, automation and optimization of rusty processes.

High-Performance Web Apps

Wether you have a spark of inspiration and want my help to make it reality, or face complex business challenges that demand lightning-fast execution, heavy user concurrency, and real-time interactive interfaces. Just drop me a mail or schedule a meeting.

How I Help Solve Your Problems

Setting Up a Bulletproof Core IT?

Don't risk your brand's reputation with flaky email routing or misconfigured domain security. I build absolute peace of mind by engineering clean, secure foundations—ensuring your communications are safe, trusted, and structured properly from day one.

Tired of Rusty, Manual Operational Processes?

Stop throwing manual labor at tasks software can handle in a second. I review your spreadsheets and bottlenecks, replacing tedious pipelines with smart scripts, elegant custom databases, and automated infrastructure that frees your team for high-value tasks.

Need to Turn a Complex Spark of Inspiration Into Reality?

Don't let engineering bottlenecks stall your next big move. I translate your concepts into clean, maintainable web systems—taking ownership of product execution so you can bring software solutions to market smoothly and without the typical developer headaches.

Facing Severe Bottlenecks or High Infrastructure Cost?

When applications deal with heavy user concurrency, legacy architectures buckle and server bills explode. I deploy highly optimized systems on the Erlang VM (BEAM) and AWS cloud architecture, delivering blazing fast real-time performance while actively slashing operational waste.

High-Performance Architecture

Unfair System Performance.
Reasonable Infrastructure Bills.

Traditional web setups often require you to throw massive hardware budgets at scaling problems. Instead, I leverage Elixir and the Erlang VM (BEAM/OTP)—the exact technology ecosystem engineered to handle millions of simultaneous processes gracefully and that's powering big players like Discord, Pinterest and NuBank.

By pairing it with Phoenix LiveView, we drop complex Javascript overhead and deliver lightning-fast, real-time user experiences. You get maximum system resiliency, a faster time-to-market, and dramatically minimized server bills.
