Solution architect & software engineer

I build practical, reliable platforms.

Hi, I’m Fatih. I’ve spent the past 14+ years shaping solution architecture, cloud platforms, and integrations so product teams can keep shipping without drama. I still dive into the code, still draw workflows on real paper when screens get crowded, and I’ve learned that steady delivery starts with plain language and honest expectations.

How I help

Architecture, delivery, and enablement

I start by listening, map what’s really happening in the stack, and turn those notes into plans that engineers, ops, and product folks can live with. I stay close to delivery until the platform is running in production, because the truth always shows up there.

Solution architecture

Making sense of brownfield systems, defining service boundaries, breaking up monoliths when it helps, and keeping APIs predictable so teams stop arguing about them.

Cloud & hybrid

Modern engineering

Kubernetes, infrastructure as code, observability stacks—mostly the boring but important things that keep cloud-native platforms stable without turning your engineers into full-time ops.

Platform & delivery

AI & data foundations

Event streams, search tooling, and lightweight ML pipelines. Useful intelligence, grounded in real data, no hype needed.

Intelligence

Leadership & mentoring

Working with founders and teams to keep priorities clear, remove the small roadblocks before they grow, and share enough context that everyone knows why the work matters.

Enablement

Project memories

Work that shaped my perspective

A few projects that reminded me why clear interfaces, dependable data pipelines, and honest communication matter more than slogans.

2025 · Belgium

Document intelligence platform @ Eaglessoft

Led a multi-tenant integration hub that ingested documents from ERPs, SaaS tools, and partner APIs, then routed them through validation, PEPPOL, national gateways, and auditors. Predictable workflows turned chaos into calm.

Retail analytics platform @ Modulairy

Pulled ERP and e-commerce data into a single analytics platform with forecasting and alerting. Retailers finally had one dashboard that matched what the stores felt.

SaaS modernization @ Mantis

Helped teams move oversized monoliths into modular SaaS and FaaS components. Releases got lighter, on-call rotations calmed down, and customers noticed.

Have a challenge worth exploring?

I keep a bit of time open each week for conversations about roadmaps, architecture reviews, or simply sharing lessons over coffee. If you think I can help, just reach out.
