Building reliable web products with clear scope and consistent delivery.
I work with startups and product teams to improve architecture, release confidence, and delivery speed — without adding unnecessary complexity.
Stack
Engineering support for scaling teams
Structured implementation support for teams dealing with technical debt, unstable releases, or unclear priorities with transparent communication.
Architecture with clear tradeoffs
Design decisions are documented early so teams understand scope, cost, and long-term maintenance impact.
Reliable application stack
Next.js 14, Supabase, and Azure SQL are used to deliver fast interfaces, stable data layers, and secure access patterns.
Security and operations discipline
Release processes, observability, and infrastructure standards are built in from the start to reduce production risk.
Practical AI-assisted delivery
Claude Code and Cursor are used for faster implementation and review cycles, while final decisions stay engineering-led.

"Dereje is an exceptional developer! I hired a total of 6 developers, and he was the last one standing at the end of the project because he was the best! He's great, very reliable, can fix things quickly, is prompt, and overall has been an incredible first hire. Ending the contract because the job was completed successfully."
Jovan Stojanovic
Ex-CEO of PhoneSales & Founder · Roasform
"Dereje delivered good work on this React development project and I enjoyed working with him. His communication was top-notch, he met all deadlines, and his skills were reasonably strong. At one point I asked for an additional milestone and he was very forthcoming that the additional work was outside his area of expertise. I enjoyed working with Dereje and will likely have additional jobs for him in the future."
