Systems I've Built

MoneyMoon SA Senior Software Engineer
Fintech Sep 2024 — Jan 2026

Challenge

Fintech monolith requiring independent supporting services for business process orchestration, multi-bank payment integrations, and scalable notification delivery.

Approach

  • Architected and extracted Offers and Investments module into an independent microservice with Camunda BPMN integration for business process management
  • Managed B2B bank integrations and payment gateway integrations, ensuring secure transaction processing and API reliability
  • Owned backend deployment pipeline architecture and dependency management, implementing CI/CD best practices
  • Designed push notification system supporting batch and individual notifications via Firebase Cloud Messaging and Huawei PushKit

Impact

Decoupled Offers & Investments business logic from the monolith, reducing processing errors and enabling the business team to update investment flows with minimal engineering involvement. Built Alinma Bank and Clickpay payment integrations from scratch; maintained existing Arab Bank and Amazon Payfort integrations — collectively processing millions SAR in monthly transactions. Created automated fund transfer system with reconciliation process for lender payouts and investor returns. Owned CI/CD pipeline maintenance and incident response across all services. Push notification system handled ~200 daily user-triggered notifications plus on-demand marketing batches of up to 100K recipients.

SaaS Jul 2018 — Present

Challenge

Egyptian e-commerce merchants needed affordable, integrated tooling for operations management — but enterprise platforms were too expensive and fragmented for small businesses.

Approach

  • Co-founded and solo-architected multi-tenant SaaS platform with schema-per-tenant isolation
  • Built end-to-end e-commerce operations: inventory management, order processing, shipping integration, automated invoicing, and real-time tracking
  • Sole engineer maintaining and evolving the platform across 8 years of production operation

Impact

Platform serving 3 active merchants, processing up to 3K orders/month at peak. Solo-maintained for 8 years — from architecture through to production support. Built as a learning project that became a real business, demonstrating long-term ownership and independent problem-solving.

Testimonials

From My Colleagues

"I worked with Mohamed at MoneyMoon, where he was a strong technical reference for the backend team. He was always supportive through code reviews, design discussions, and helping break down and estimate backend work. I learned a lot from his approach to system design, production readiness, and taking ownership, and I'd be happy to work with him again."

"Tarek is one of the best engineers I worked with. We collaborated on building the wallet system at MoneyMoon. He was proactive and handled production issues with composure and seriousness at the same time. He always lends a helping hand."

Hesham Adel Senior Software Engineer Colleague at MoneyMoon

"I worked as a backend intern under Mohamed at Suiiz App, and he had a big impact on how I approach backend development. He introduced me to writing tests and working with TDD, and took time to review my code and explain his feedback clearly. That experience helped me become more confident as an engineer and played an important role in me receiving a full-time offer."
