Illustration of coding

Hi, I'm Ali 👋

LinkedIn Hackerrank

I'm a Principal Software Engineer / Software Architect with 20+ years of experience building backend and distributed systems.

I enjoy working on complex engineering problems where reliability, scalability, security, and maintainability matter.

What I work with

  • ☕ Java & Spring Boot
  • 🧩 Microservices & distributed systems
  • 📨 Apache Kafka
  • ⚡ Redis
  • 🐘 PostgreSQL
  • ☸️ Kubernetes
  • 🔐 Identity, OAuth2 / OIDC & security
  • 🏢 Multi-tenant architectures
  • ☁️ Cloud-native systems

Areas I enjoy

  • Designing scalable and resilient backend systems
  • Distributed systems and asynchronous processing
  • Performance optimization
  • Security and identity systems
  • Multi-tenant architectures
  • Reliability and incident analysis
  • Turning complex problems into simple solutions

Engineering mindset

I believe that small technical problems can become significant operational, performance, or security risks when they are allowed to accumulate.

I like to understand why something is happening, rather than only fixing the immediate symptom.

Sometimes the best solution is a sophisticated architecture.

Sometimes it is a very small change.

The important part is knowing the difference.

A few things I've worked on

  • Identity and authentication platforms based on OAuth2, OIDC and OpenID Federation
  • Multi-tenant systems with tenant-specific security and cryptographic keys
  • HSM-based key management and automated key rotation
  • High-throughput asynchronous processing with Kafka
  • Distributed caching with Redis
  • PostgreSQL performance optimization
  • Highly available microservices running on Kubernetes
  • Production incident analysis and reliability improvements

I'm currently interested in Senior / Staff / Principal Backend Engineering and Software Architecture roles, particularly where I can combine hands-on development with system design and technical leadership.
