Tarkan Cengiz

I design, build, and operate entire production systems — from eBPF in the Linux kernel to my own Kubernetes cloud — by myself.

who I am

One person. The whole stack.

I've been building software for about fifteen years — since high school. Today I work alone and ship like a team: product, full-stack engineering, and DevOps, taking an idea to a deployed, observable production service in hours rather than weeks.

My speed isn't shortcuts. It's infrastructure I built and still maintain — my own k3s cloud, my own boilerplates, my own models on local metal. Because I built the cores myself, I can trust what I ship and verify everything an AI hands me.

own cloud

Everything runs on a self-hosted Kubernetes cluster I operate end-to-end: private registry, Traefik ingress, auto-TLS, and full Loki / Grafana / OpenTelemetry observability.

on-prem intelligence

Local LLMs in the loop on my own GPU. No cloud lock-in, no data leaving the network, zero per-token cost.

kernel to cloud

From eBPF and systems internals up through DRF APIs, React 19 frontends, and native mobile — one person, the whole stack.

verified, not vibed

AI accelerates; deep systems knowledge guarantees correctness. I verify output instead of trusting it blindly.

what I build

A few of the systems I've built.

co-founder · ai agent security

Interposed

Runtime security & observability for autonomous AI agents — bridging high-level LLM intent with kernel-level eBPF activity to catch prompt injection and data exfiltration.

eBPF · OpenTelemetry · Go · Python · K8s · MCP
independent product · vehicle valuation

Aracını Bil

A used-car valuation platform on its own live-scraped market data, with a transparent engine whose every coefficient is A/B-tested against the real comparable pool before it ships.

Django · Elasticsearch · Next.js · FastAPI · K8s
independent product · gaming media

Kadim Vadi

An editorial platform for gaming, with an MCP-based AI agent that drafts only from retrieved sources — it refuses to hallucinate — plus a custom editor and a canvas Instagram designer.

Django · FastMCP · Ollama · Next.js · SeaweedFS

beyond the terminal

Away from the terminal.

I read and think a lot — cosmology, epistemology, the apophatic edges of theology, and Turkish history. I write long-form for Kadim Vadi in a register I care about. And I keep a hand in things that are made, not just typed: a 3D printer humming, a card game with friends, a guitar, and the occasional deep dive into a game world.

Let's build something that runs.

Solo projects, consulting, or an interim lead role — I'm reachable.
