About
Mehmet Sarı
Solution Architect & IT Infrastructure Specialist (MSP) · Security and Software Focused
I come from inside the field. I never narrowed down to a single area; system architecture, network, server infrastructure, large-scale buildouts, software development and system security are pieces of the same picture for me.
I bring up complex infrastructures, scale them and make them sustainable under real load. I know how systems that operate under real outage risk and real operational pressure on the field need to be designed.

Operations
I do not design a system around how it runs, but around how it breaks, how it can be recovered and how it can be made more resilient.
— This blog is the direct extension of that mindset
Right Now
Things I am working on these days
Main Focus
Zero-trust network models and segmentation architectures at enterprise scale
My Own Projects
ITWISE AI (MSP operations automation) and ITWISE Finance (e-invoice/bank/Paraşüt reconciliation) — from idea to production
Experimenting

My Main Working Axes
System Architecture
I design systems for enterprise structures with high availability, scalability and operational continuity in focus.
- Distributed architecture design
- Load balancing and failover
- Redundancy and disaster recovery
- Large-scale platform planning
Network & Infrastructure
From the network layer to the data center, from edge structures to service connections, I build and manage end-to-end infrastructure.
- Routing / switching
- Firewall and segmentation
- VPN, WAN and edge topologies
- Data center and server infrastructure
Server & Platform
I bring up critical systems on physical, virtual and cloud environments; I orchestrate monitoring, automation and continuity.
- Linux / Windows server stacks
- Virtualization and clustering
- Monitoring and capacity planning
- Cloud and hybrid platforms
Software & Automation
By combining infrastructure knowledge with software, I build solutions that speed up operations, simplify maintenance and improve security.
- Backend services
- APIs and integrations
- Automation and scripting
- CI/CD and platform tooling
System Security
I treat security not as a layer added later, but as a fundamental part of the architecture.
- Hardening and access model
- Logging and traceability
- Secure network architecture
- Risk reduction and operational security
Operational Leadership
I do not just build technology; I also make sure these structures are long-lived, manageable and sustainable for the teams.
- Standardization
- Documentation
- Incident management
- Technical guidance and mentorship
Side Projects
I Built These Too
ITWISE AI
ÜretkenlikHybrid AI automation platform (MSP)
A hybrid AI automation platform. Activity Tracker monitors computer activity, while the OpenClaw autonomous-agent layer automates MSP operations (reports, quotes, alert triage). Sensitive data runs on a local LLM (Ollama), open analysis on the Claude API.

ITWISE Finance
FinansFinance analysis & reconciliation platform
A hybrid finance-analysis platform that reconciles e-invoice, bank transactions and Paraşüt data, surfacing mismatches and anomalies. Sensitive financial data is processed locally.

My Working Principles
My Decision Frame
I make technology choices not for the trend, but for the business goal and operational reality.
For me, what matters is not just that the system runs, but that it can recover quickly when things break.
Security, performance and ease of maintenance are pieces of the same architecture that must be solved together.
I see software and infrastructure not as separate worlds, but as complementary layers of the same system.
What Sets Me Apart
Not One Layer, the Whole System
There are plenty of profiles in the industry who know networking but not software, who know software but have never seen operations, or who have built infrastructure but never internalized security. My difference is being able to read all these layers together.
My decisions are not just technically correct, they are also operationally realistic. I do not pick the "best design"; I pick the one that "stays standing in the field".

Frequently Asked Questions
What areas are you available for consulting or collaboration?
System architecture, large-scale infrastructure design, network segmentation, enterprise security hardening, SRE / operations improvement, and AI-assisted automation projects. Instead of small, quick consultations, I focus on structures that produce real operational value.
Are your blog posts written by AI?
Since launch, this system has been a fully automated pipeline running every hour. I provide the persona and the context, the Gemini models produce the content, and posts that pass the validation layers get published. Right now the blog itself is the live example of the "AI + infrastructure" combination I keep talking about.
Why do you self-host?
The operational practice itself matters to me. The Astro + Node + SQLite + Nginx + systemd + Let's Encrypt chain that publishes my blog also reflects the disciplines I apply in the field: atomic deploy, daily backup, observability, change safety. It is a small model of the system I am trying to describe.
Your favorite tools?
It depends on context: at enterprise scale Terraform, Kubernetes and Prometheus earn their place; in my own projects radical leanness wins — this blog runs on a single VPS with Astro + Node + SQLite + Nginx. My common ground: iTerm + zsh, JetBrains, Claude Code and a multi-AI pipeline. For details, check my /uses page.
How can I get in touch?
You can message me directly via GitHub or LinkedIn. I try to reply within a few days to well-formed messages with clear context. For general technology talk, the comments under the posts are also open.
Contact
Shall we work together?
Reach out for architectural decisions, enterprise infrastructure design, security hardening or operational improvement projects. For short questions the comments under the posts are open; for more in-depth conversations LinkedIn is the fastest path.
Topics I am available for
- Enterprise infrastructure and architecture consulting
- Network segmentation and zero-trust transition
- SRE and operations discipline improvement
- AI-assisted automation pipeline design
- Not available for small, urgent ad-hoc consulting
