Senior DevOps Engineer & R&D Team Lead @ Vendor Box

I build CI/CD, Kubernetes platforms and monitoring that run themselves — secure by default, written down as code, and quiet at 3 a.m.

01 · About

I’d rather describe a system in code than build it by hand. Infrastructure is code, every change goes through a pull request, and a good system tells you it’s broken before anyone else does — then fixes what it can on its own.

I’ve worked in DevOps and DevSecOps since 2019, including two years of security-focused QA, across Kubernetes operations, cloud platforms, MLOps and RAG systems. Today I’m a Senior DevOps Engineer and the R&D Team Lead at Vendor Box, and I consult for İVEN Bilişim. After hours I build minderhq, a self-hosted AI platform I first imagined in 2023 while working on Monitra. A home lab tests all of it and feeds this site’s lab journal.

I wrote my first website in Notepad, for a free 10 MB host, while still in primary school. High school brought Pascal and cybersecurity forums; university brought assembly and the keys to the department’s lab. A guitar pulled me into sound recording and a studio in Kadıköy; a digital processor that actually sounded good pulled me back to software. I taught myself Linux, which led me to Hackerspace Istanbul; later I helped found two university labs, Sparkgo and BAU Future Lab, an IoT lab funded with Intel’s support.

02 · Featured work

03 · Work with me

Let’s make your infrastructure run itself.

Consulting and hands-on delivery, in whatever shape fits: a one-off audit, a fixed-scope build or ongoing support — held to the same standards as the production systems I run.

How I work

Issues that end the debate

Every finding comes with the details and a cause-and-effect chain, so it gets picked up — not argued about in next week’s meeting.

Code, not clicks

What I set up is written down as code and reviewed, so you can rebuild it without me.

Leaner every time

I take things away before I add: fewer moving parts, easier installs, updates that apply themselves.

  1. 01

    CI/CD & DevSecOps

    Pipelines with security built in: GitLab CI or GitHub Actions on your own runners, signed images, a private registry with vulnerability scans.

  2. 02

    Kubernetes & platforms

    K3s or Kubernetes with Argo CD and Helm, on Proxmox or in the cloud — a platform your team can ship to without asking anyone.

  3. 03

    Observability

    Prometheus, Grafana and alerts that matter, straight to your phone — so you hear about problems before your users do.

  4. 04

    Self-hosted AI

    LLMs and RAG on your own hardware, with answers that cite their sources — plus n8n automations that keep your data in-house.

  5. 05

    Small office & homelab servers

    A server that runs itself: Proxmox, backups, UPS and remote access, defined as code.

    Senior DevOps Engineer & R&D Team Lead · Vendor Box

    Remote

    Two roles at once. As Senior DevOps Engineer I take care of the platform’s infrastructure and delivery; as R&D Team Lead I lead the team that decides what we build next.

    • A fully autonomous, Jira-integrated delivery pipeline, with separate test and production environments
    • Docker and Kubernetes environments, infrastructure as code with Ansible; monitoring, logging and access control

    Founder · R&D project lead · RAG core engineer · minderhq

    Own product · idea since 2023

    A self-hosted, local-first AI platform: LLMs, RAG pipelines and knowledge graphs on your own hardware, extended through a public plugin ecosystem. The idea took shape in 2023, while I was working on MLOps and RAG for Monitra; in 2026 it became a product — and an R&D project I lead as its technical architect and RAG core engineer.

    • Experiment design and hypotheses; technical architecture; validating models, hardware and security before the pilot
    • RAG module contracts, reference pipelines and adapters, compared in controlled experiments
    • Budget-aware method selection driven by each document’s profile

Built things before I deployed them.

Long before pipelines and clusters there was Notepad, a guitar and a lot of time in labs: the electronics lab of my vocational high school, the department lab I ran at university, a recording studio, a hackerspace and two labs I helped found — with Linux, self-taught through online communities, in between. That is where I learned to build things, to lead a team, and to explain technical work to people outside the field.

  1. Primary education

    A first website

    HTML · Notepad

    My first website was hand-written HTML, typed in Notepad and uploaded to the free 10 MB of hosting cjb.net gave away back then.

  2. until 2007

    Şişli Vocational and Technical High School

    Electronics · Pascal · security forums

    I wrote Pascal, spent hours on cybersecurity forums trying to learn whatever I could, picked up the guitar, and sat in on the senior classes’ lab lessons of my own accord, helping the older students along the way — the earliest training of my R&D instincts and hands-on skills, under my lab teacher Oğuz Kaan Bozkuş.

  3. 2007 — 2011

    Marmara University

    Electronics & communication · lab lead

    I was an evening-programme student, but my days started early in the lab: as assistant to our department coordinator, Uğur Kesen, and the person responsible for the department’s laboratory, I set up the labs and supported the instructors teaching there. This is also where I learned assembly.

  4. 2009 — 2011

    A music studio in Kadıköy

    Sound recording · repairs

    The guitar pulled me into recording technology. In parallel with university — sometimes at the expense of my evening classes — I worked at a music studio in Kadıköy. I helped musicians through both kinds of sessions: multitrack recordings, with a microphone on every instrument, and live takes of the whole band captured by microphones set up in the middle of the room. I also repaired the studio’s gear.

    Until then I had lived by Serdar Öztop’s line, “digital should have its limits.” Then a digital processor landed on my bench that simply sounded good — and I realized it was time to leave that line behind and focus on software.
  5. 2011 — 2013

    Linux, self-taught

    Pardus 2011 · online communities

    After the studio I turned to Linux and set out to learn it on my own. It started with a Pardus 2011 DVD, mailed out for the price of shipping — the beginning of my focus on Linux. From there I joined online communities, asked questions and dug through everything I could find. That search is what led me to Hackerspace Istanbul.

  6. 2013 — 2015

    Hackerspace Istanbul

    Linux · cybersecurity · PCB design

    A two-way exchange. The community deepened my Linux and took the security I had picked up on forums much further; in return I helped with PCB design and with improving their hackathon projects. I attended their trainings and later took on roles in running them.

  7. 2013 — 2019

    Bahçeşehir University

    Electrical & electronics · graduate labs

    My degree years were lab years. Rather than go home and come back early for lab work before classes, I often just stayed in the lab. At night, to keep busy, I sat in on master’s courses and helped the lecturers run the hands-on sessions of their big data and Linux classes for graduate students. Another lab, another reason to stay.

  8. 2015 — 2018

    Sparkgo

    First lab · funded by the university

    The first lab I helped found, funded by Bahçeşehir University. Sparkgo gave student science and technology projects a stage the school could proudly show — and taught me how to tell the story of technical work.

  9. 2015 — 2018

    BAU Future Lab

    IoT lab · funded with Intel’s support

    Next came BAU Future Lab, funded with Intel’s support — and this was the hands-on one. We built real IoT projects on embedded boards, sensors and Linux, and learned what it takes to make connected devices work outside a demo.

A home lab that runs itself

One Proxmox node, a NAS, a Raspberry Pi and a UPS. Everything is defined as code, updates itself every night and rolls itself back when something breaks.
