Three flagship builds with full build stories — the problem, what I personally built, and the decisions behind it.

Bayment — FinTech Virtual Card & P2P Platform

Lead Full-Stack Engineer · Flutter Mobile + Django REST Backend

Full-stack financial technology platform engineered to eliminate international payment friction for African consumers. Combines programmatic Mastercard virtual card issuance, dynamic card freezing, sub-second P2P wallet settlement, and African bank gateway integrations.

Programmatic virtual card creation with tokenized CVV and dynamic spend caps.
Double-entry accounting ledger with sub-second P2P fund transfers.
60 FPS cross-platform Flutter client with biometric security & balance telemetry.

Seri LMS — Enterprise Learning Platform

Backend & Systems Architect · NestJS + Next.js Monorepo

The real challenge here wasn't the code — it was trust. Students had to pay with local rails (Chapa, Telebirr, bank transfer) without ever getting scammed, and course videos had to stay off Telegram. So I built the payment audits and the video lock-up myself.

Signed, token-locked Bunny Stream playback with per-session expiry — no direct URL sharing.
Redis BullMQ workers absorbing enrollment bursts so course seats can't double-sell.
Chapa webhooks plus manual bank-transfer audit trails, reconciled to the Birr.

Fitawrari / ፊታውራሪ — Ethiopia's Verified Car Marketplace

Full-Stack Architect · Next.js + NestJS Turborepo

Car buying in Ethiopia runs on brokers — some legit, some scammers, and buyers can't tell until it costs them. Fitawrari puts sellers, buyers, and dealers on one platform where the dealership itself is verified. Trust is the product.

Verified dealer listings priced in ETB, with direct call/WhatsApp handoff built for how deals actually close.
Cut a vehicle page from ~15 MB of raw camera photos to under 800 KB with responsive WebP.
Shared Zod schemas keep browser and API validation in exact agreement.

The Engineer Behind the Code

I am a Software Engineer and honor graduate of Addis Ababa Science and Technology University (AASTU), specializing in cross-platform mobile engineering and scalable backend infrastructure.

My technical sweet spot is building seamless, native-performance applications in Flutter and backing them with high-throughput distributed systems in Go and Python/Django. I prioritize Clean Architecture, type safety, test isolation, and dependable production performance.

Selected for A2SV (Africa to Silicon Valley), an elite engineering talent program backed by Google, where I completed rigorous algorithmic acceleration and solved 600+ complex problems across LeetCode and Codeforces.
