Observability
Master metrics, tracing, and logging with Prometheus and Grafana.
Git Pro Workflow
Master interactive rebase, cherry-pick, bisect, and trunk-based CI with protected branches.
Python Backend Career
4 tracksFrom Python syntax to FastAPI production APIs — SQL, testing, and async routes for building robust Python backends.
Testing & TDD
Write reliable code with pytest: assertions, fixtures, parametrization, and red-green-refactor.
Data & MLOps Engineering
3 tracksPostgreSQL deep dives, SQL mastery, and async API consumption — the data engineering backbone for analytics and ML pipelines.
AI Engineering Career
3 tracksPrompt engineering, agentic AI systems, and production LLM app development with Retrieval-Augmented Generation pipelines.
Agentic AI Agents
Build autonomous agents with LLM prompting, tool-calling, memory, and LangGraph.
Prompt Engineering
Zero/few-shot prompting, chain-of-thought, RAG prompting, and defenses against prompt injection.
LLM App Development
Embeddings, vector DBs, similarity search, and retrieval-augmented generation pipelines.
Systems & Infrastructure Career
