Cursor AI App Debugging and Completion
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.

Full Stack Developer
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.

Job Success
Addis Ababa, Ethiopia - 3:12 am local time
What I have shipped:
Healium Sono
Real-time AI ultrasound teleguidance for cardiologists and OB/GYN specialists. A remote specialist connects via Zoom Video SDK and guides an on-site clinician through a live diagnostic scan while an AWS Lambda and FastAPI pipeline runs AI analysis on ultrasound frames in parallel. HIPAA-compliant multi-tenant Supabase architecture. In production.
Healium CKD
AI kidney disease detection from ultrasound imaging. Automated pipeline that ingests images, identifies CKD markers, and returns structured clinical findings with severity scores in under two seconds.
AI Voice and Booking Systems
End-to-end inbound call automation using Vapi and N8N, AI answers calls, qualifies callers, handles objections, books appointments, and logs everything to CRM automatically. Built versions of this integrated with EMR systems that have no public API, using authenticated automation layers with full audit logging.
Roasform
A CRM-integrated AI form and lead qualification platform for high-ticket sales businesses. Forms adapt dynamically to each prospect's answers, score leads in real time, push qualified contacts into the CRM pipeline automatically, and trigger follow-up sequences based on score. Stripe billing. Live product with paying customers.
Document and Workflow Automation
AI agents that read PDFs, extract structured data, and push it into spreadsheets or databases automatically. Multi-tool orchestration systems where one event triggers actions across five or six connected platforms simultaneously, CRM, email, messaging, and internal tools, all in sync without manual work.
My stack:
Next.js, React, FastAPI, Node.js, Python, Supabase, PostgreSQL, AWS Lambda, OpenAI, Claude, LangChain, N8N, Vapi, Twilio, Stripe, Zoom Video SDK, Docker, Terraform.
Who I work with:
Founders and teams who need a senior engineer who can own the architecture end-to-end and ship. Businesses that need AI agents and automation systems to replace manual work, lead qualification, document processing, call handling, and internal operations. Health-tech and other regulated teams that need someone who has already built under HIPAA, PIPA, and FDA-adjacent constraints and knows the difference between a demo and something that survives production.
If your project needs to actually work under compliance pressure, scale pressure, or just the pressure of running unattended, send me a brief description of what you are building, and I will honestly tell you whether I can help.
