Software & DevOps Engineer — AI | LLM | Agents Infrastructure | Kubernetes | Hardware

Interests and Objective

Delivers across the stack — backend, infra, hardware, ML/LLM workloads — with AI agents and AI pipelines as everyday tooling for codegen, refactors, test scaffolding, and code review; agent-driven development as the default workflow. Foundation in Python, Rust, TypeScript, distributed systems, and Kubernetes, including bare-metal, hardware-controlled clusters. Ships production LLM agents (RAG, tool-using, MCP) and LLM/RAG evaluation pipelines. Code costs nothing, no human review: AI-driven SDD/TDD/BDD — agents write the spec, the tests and the code.

Skills

AI / Agents

  • LLMs: OpenAI, Claude (Anthropic), Hugging Face / open-weights

  • Calling patterns: function / tool calling, structured outputs (Pydantic, JSON Schema), streaming, vision, prompt caching, batching

  • Agent frameworks: LangChain, LangGraph, PydanticAI, CrewAI, OpenHands, plain-Python tool-using agents

  • Agent patterns: ReAct, planner-executor, multi-step orchestration, sub-agents, autonomous + human-in-the-loop, escalation rules

  • MCP (Model Context Protocol): production MCP servers (pois-mcp), MCP clients, tool / resource / prompt exposure to AI assistants

  • RAG stack: FAISS, pgvector, Weaviate; OpenAI and sentence-transformers embeddings

  • Retrieval: hybrid search (BM25 + dense), reranking, chunking strategies, query rewriting, citation grounding

  • Knowledge synthesis: spec / feature registries, internal docs, code search, chat history, ticket / PR history fused into agent context

  • Evaluation: golden datasets, hallucination detection, prompt regression, automated graders, LLM-as-judge with calibration, agent-behaviour validation; eval in CI

  • Prompt engineering: system-prompt design, few-shot, schema-driven output, guardrails, jailbreak resistance, persona / role design

  • Agent ops: cost / latency budgeting, retries, fallbacks, caching, observability (traces, token spend, eval drift)

  • Safety & compliance: PII redaction, content filtering, audit trails, deterministic mode for regulated paths

Agent-Driven Development

The way I build, not just what I build. Humans set direction; agents synthesise knowledge across the codebase, specs, docs, and PR history; humans review.

  • Workflow: Spec-Driven Development — Concept → Plan → Spec → Code → Feature discipline; spec / plan / feature registry the agents read from and write back to, referenced in code and PRs.

  • Project rails: CLAUDE.md and AGENTS.md define design principles, commit conventions, and no-go zones for autonomous edits.

  • Knowledge sources for the agent: code, spec/feature registry, ADRs, runbooks, prior PR diffs, eval logs — all reachable through tools or RAG.

  • Practical use: codegen, refactoring, test scaffolding, code review, architecture sanity checks, runbook authoring, IaC and tooling work, migration drafting.

  • Quality gates: typecheck, tests, LLM evals, security review — every PR; agents must produce green CI before a human approves.

  • Outcome on real projects: pois.world shipped solo (nine microservices, Rust core, four clients); vav-v2 (German tax / EÜR accounting) built the same way with strict Decimal correctness and tracked-table reinit pattern.
