About Salim

I build and evolve platforms that help engineering teams move faster — without sacrificing reliability.

I’m a Platform Engineer and Tech Lead specializing in API-first architectures, event-driven systems, and cloud-native platforms. Over the past years, I’ve worked across banking, retail, luxury, and public sector environments, leading modernization initiatives in complex, large-scale systems.

My focus is not just writing code — it’s structuring foundations.

I’ve led cloud migrations to Kubernetes, designed event-driven data platforms powered by Kafka, implemented API governance frameworks, and built shared engineering capabilities such as CI/CD pipelines, observability layers, and synthetic monitoring platforms. My work often sits at the intersection of architecture, platform enablement, and cross-team alignment.

What drives me is transforming legacy systems into scalable, operable, and resilient platforms — while helping teams adopt better standards, clearer ownership, and stronger engineering practices.

Core expertise:
• Platform Engineering & Cloud Native (Kubernetes, Docker)
• Event-Driven Architecture (Kafka, data pipelines)
• API Design & Governance
• CI/CD & Engineering Excellence
• Cross-team technical leadership & mentoring

I’m particularly interested in roles where platform thinking meets engineering leadership — shaping technical direction, enabling teams, and driving modernization at scale.
