High-throughput backend engineer.
I design and scale distributed financial systems processing millions of monthly transactions and handling thousands of peak RPS. Focused on concurrency, resilience, and zero data loss, I build systems that never fail under load.
Identity
Pragmatism over hype.
I’m a backend focused software engineer specializing in distributed systems, financial ledgers, and high-concurrency architecture. I focus on building resilient systems that continue to operate under failure, rather than chasing frontend trends. My work emphasizes idempotent APIs, aggressive caching, and defensive programming to ensure data integrity and reliable business logic, even when database nodes fail or traffic spikes.

Projects
A selection of projects I contributed to, showcasing scalable, reliable, high-performance systems powering real-world financial applications.
CBE Connect
A cross-border remittance app and multi-currency digital wallet for Commercial Bank of Ethiopia, enabling fast, secure, and affordable money transfers for the Ethiopian diaspora.
The Challenge
Ethiopian people living abroad face slow, expensive, and unreliable methods to send money to their families back home. Existing solutions lacked transparency, speed, and convenience.
The Solution
Built scalable backend services for cross-border remittance, including transaction processing, currency conversion, and integration with banking systems.
Dashen Super App
A digital banking super app enabling instant transfers, QR payments, and integrated financial services for over 2M users in Ethiopia.
The Challenge
Delivering a super app required enabling high-frequency, real-time financial interactions while integrating with existing core banking systems. Supporting payments, transfers, and third-party services in a single platform introduced challenges around latency, high concurrency, and maintaining transactional consistency across distributed services.
The Solution
Developed scalable backend services and APIs for real-time transfers, payments, and third-party integrations, ensuring transactions are reliable, fast, and scalable for everyday users.
Gift Ethiopia
A cash and gift card remittance service enabling diaspora users to send funds and gift value directly to recipients in Ethiopia as part of a broader cross‑border remittance suite.
The Challenge
Ethiopian diaspora members abroad lacked convenient, secure, and compliant methods to send money or thoughtful gifts back home. Traditional remittance paths were costly, slow, and fragmented, and there was no unified platform for digital gifts and cash transfers to Ethiopia.
The Solution
Built an online remittance solution where diaspora customers can send cash gifts, digital gift cards, and value directly to their loved ones in Ethiopia. The platform supports input of receiver details and facilitates secure transactions through partnered financial infrastructure and payment providers.
Technical Expertise
Technologies and tools for designing secure, scalable, and resilient distributed systems at production scale.
Languages
Primary languages used to build high-throughput backend systems.
