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.
Notes on shipping AI to production — architecture, LLMs, MLOps, and lessons from the field.
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.
Sub-agents are the most oversold feature in agentic coding. They're also, used precisely, the best answer to the two hardest problems in agent work: context pollution and self-grading.
Small, free, browser-based things I built from my work — no sign-up.
Generate a drop-in rules file (AGENTS.md / CLAUDE.md) that turns a sycophantic coding agent into an expert. Toggle behaviors, then copy or download.

Featured case studies
Broadcast live on national TV — real-time speech-to-speech, on air
A zero-retry, on-air AI interviewer: streaming STT → LLM dialogue management → low-latency TTS, with guardrails for live broadcast.
Read case study → Audio · Speech~40% word-error-rate reduction on internal test sets
LoRA fine-tuning + data augmentation to specialise Whisper for German dialects and domain speech — efficient, honestly measured, deployable.
Read case study → NLP · LLMGrounded, cited answers over enterprise documents
Hybrid retrieval + reranking + citations + web search + feedback loops, deployed under EU data constraints — answers people can actually trust.
Read case study → Agentic · LLMIntent-based routing to specialized agents
An orchestrator that classifies intent and routes complex queries to specialised agents — reliable, cost-bounded, and maintainable vs. a monolithic prompt.
