Hasan Halacli — AI Solution Architect & Technical Lead
10+ years turning AI transformation into production-grade systems — LLMs, MLOps, and cloud-native platforms built for security, reliability, and EU data residency.
I specialize in building end-to-end AI solutions, from data collection to deployment and maintenance, leading teams to deliver impactful results.
From classical ML to Deep Learning and Fine Tuning LLMs
Building scalable and efficient data pipelines.
Using cloud services to build scalable and efficient solutions.
Building efficient workflows with Power Platform and N8N.
I help engineering organisations make AI part of how they build software — deliberately, and in a way that survives an audit. My day job is running an AI platform for a critical-infrastructure operator under EU regulation, where an unreviewed change is a regulatory event rather than a bug. That is the standard I bring.
Your developers already use AI to write code. This makes it deliberate: what the tools may touch, who reviews the output, and how you prove it later.
The demo works. Now it needs real users, real data and someone on call. This is the gap where most GenAI projects quietly stall.
Find out which of your systems are in scope, what each one obliges you to do, and what is missing — before a customer or auditor asks first.
Point the Repo Reality Check at one of your public repositories. Five agents read it and hand you findings drawn from your own code — useful whether or not we ever speak.
Send me the report. I will tell you what I would fix first and what I would leave alone — including if the answer is that you need nobody.
Fixed scope with a deliverable your team keeps: the rules, the gates, the review protocol, running in your pipeline.
Find out in two minutes. The audit asks eight plain questions about how your teams work today and hands you a report written for people who do not read code.
Notes on shipping AI to production — architecture, LLMs, MLOps, and lessons from the field.
I built a tool that matches a company against every public tender published in Germany — the agents were the easy part. The four failures between a working demo and a live one.
You already know you should review agent code — I've written three posts on why. This is the how: what to read first, the failure signatures that look correct, and the tests you can actually…
A rule in a markdown file is a request. The agent honors it right up until 'temporarily' hardcoding the token becomes the path of least resistance. Requests need enforcement behind them.
Small, free, browser-based things I built from my work — no sign-up.
Paste your company website. Four agents read it, scan every public tender published in Germany in the last two weeks, and return the ones that fit — with the reason, the deadline and the link. Live data, no sign-up.
Find my tenders NewPaste any public GitHub repo and watch five agents read it live — review coverage, unpinned dependencies, missing CI gates. Real findings from real data, not a questionnaire.
