Backend developer · Eskişehir, TR
I build backends that hold up in production, computer-vision pipelines that turn camera footage into maps, and gameplay systems in C++. Live work includes an education platform, corporate sites and a video platform.
Three projects in depth. Open any of them for screens and stack.
Road-damage detection from bus-mounted cameras.

Milestone 0 of 12 · complete
34/34 automation tests · 606 Fab packs inventoried
Education platform in production, live since 20 August 2026.
Anime video platform with a searchable catalogue, season calendar, multi-language subtitles and a hybrid P2P and server player.
Anime subtitle translation service. Produces .ass subtitles without touching the video: audio timing, OCR of on-screen text and context-aware translation across eight languages.
Live support built around the conversation: an Express and Socket.IO gateway, a 5 KB widget loader with an iframe UI, an operator inbox with a visitor card and end-to-end tests.
Corporate site for a glass-balcony and joinery company: 23 static pages with no build step, brand-guide tokens, measured WCAG contrast and JSON-LD.
Honey e-commerce on TanStack Start and Cloudflare D1 and KV, with Turnstile, card payments and a local workflow that never touches production data.

Node.js and Python services, REST and GraphQL APIs, PostgreSQL, MongoDB and Redis, tuned until the queries are fast and the servers stay calm under load.
GET /api/trainings → 200 · cached in Redis
YOLO pipelines, GPS map-matching, speech timing, OCR and LLM tooling, with privacy rules enforced in code.
frame → blur() → detect() → map_match()
Gameplay systems in Unreal Engine 5 and C++, built data-driven and covered by automation tests from the first milestone.
UPROPERTY(EditDefaultsOnly) FSurvivalNeeds Needs;
Every system I build has a moment where something has to be trusted: an agent's approval, a camera frame, a payment. I design that moment first, and I write down what is still unfinished.
Request held · waiting for server-verified approval
confirm flag: true → ignored
The server checks approval itself.
Approval is a server-side fact. Every spend path asks the network first.
A missing token, a silent endpoint or an unreadable answer ends in refusal. A gate opens only when it can see.
A privacy rule that can be forgotten will be. Asfalya throws an exception on any unmasked frame.
Every repository carries a status table with its open items: a recall target missed, a link that is simulation only, a legal permission folder that is still empty.

AGPL-3.0Source ↗
Network-verified trust for AI agents that spend money.
An MCP server that runs real Google Ads and Meta campaigns behind server-side spending guards. Before a human is ever prompted, it asks the mobile network (GSMA Open Gateway and CAMARA, through Nokia Network-as-Code) whether the approver's line has been taken over.
Campaigns are always created paused, budget increases wait for the approver, and only the account owner can raise the spending ceiling. Anyone using the service can read its code under AGPL-3.0.
The trust chain, and where it honestly stands
| # | Signal | Question it answers | State |
|---|---|---|---|
| 1 | simSwap.check | Was the approver's line taken over recently? | Live |
| 2 | numberVerification | Is the approval coming from the owner's own device? | Simulation only |
| 3 | deviceStatus.reachability | Can the line receive data or SMS right now? | Live |
| 4 | deviceStatus.roaming | Is the line in the expected country? | Live |
| 5 | deviceSwap.check | Was the line moved to a new device? | Live |
| 6 | callForwarding | Is unconditional call forwarding active? | Live |
Five of six links are verified against live endpoints. The account runs in Nokia's Simulator mode: the wire is proven, the operator integration is still pending. Number Verification is a device-side OIDC flow that no back end can call.
Open-source MCP server for safety-gated Google Ads management. An AI agent can manage campaigns while every budget increase waits for a verified human approval.

The arrow-key and Escape handling repeated in FindInput and ReplaceInput now lives in one shared helper, covered by five new unit tests. Resolves issue #199892.
PR ↗A fix for NASA's mission-control framework: the plot view refreshes its Y-axis label as soon as the label changes.
