Hi, I’m Abdulshakur Ahmed (Hanad)

Payment Systems Architect | Full-Stack Engineer | Builder of Financial Infrastructure

I design and implement secure, scalable financial systems — from national instant payment infrastructure to distributed microservice platforms.

Currently leading payment switch architecture and ISO 20022 integrations, while building Helios, an SME Operating System designed to modernize how small and medium businesses operate across emerging markets.

Helios is built to simplify operations, enforce real accounting discipline, enable automation, and give SMEs the infrastructure they need to scale with confidence.

What I Work On

  • National-scale Instant Payment Systems (IPS)
  • ISO 20022 financial messaging (pacs.008, pacs.004, etc.)
  • Secure system design (PKI, digital signatures, compliance layers)
  • Microservices & distributed architectures
  • High-availability backend systems (.NET)
  • Modern frontend systems (React)

Engineering Principles

  • Build for correctness, not shortcuts
  • Design for scale from day one
  • Security by default
  • Clean architecture & software craftsmanship
  • Continuous learning and mentoring

About Me

  • Cloud experience: Azure & OCI
  • Strong background in RDBMS and transactional systems
  • Advocate of BDD / TDD practices
  • Passionate about mentoring and growing strong engineering teams
  • Focused on building systems that outlive trends
