🥇Top Rated on Upwork — 4+ Years Delivering Results Agentic AI, DevOps & Automation | Modular Systems, Built to Scale I design modular, production-grade systems that blend AI, DevOps, full-stack engineering, and automation — from MVPs to end-to-end pipelines. My work covers: • Architecting multi-agent AI workflows (Agentic systems) • Building full-stack modules in PHP, JS, Python, or headless CMS integrations • Designing scalable RAG pipelines with embeddings and vector search • Scraping, cleaning, and structuring web data for automation or analytics • Orchestrating automations in Bash, Python, or even legacy PHP/Perl • Maintaining and extending complex backend stacks with minimal friction • Setting up CI/CD pipelines, systemd services, cron jobs, monitoring, and logging • Delivering Linux-first, cloud-agnostic deployments (Docker, Git, Debian) • Integrating external APIs and webhooks into real-time workflows • Converting unstructured content into structured, queryable data sources • Deploying AI agents via chat, voice, or CLI — with transparency and control Approach: No fragile dashboards. No black boxes. Just fast, auditable systems that scale cleanly. I favor modularity, shell-first design, and clear automation over abstracted tools. Tech Stack Highlights: Python, Bash, FastAPI, Docker, Redis, PostgreSQL, Git, CI/CD, systemd, Pinecone, Chroma, Cohere, OpenAI, Debian/Linux PHP (Core, Procedural, Shell-integrated), Perl (Sysadmin/Legacy), JavaScript (Node & Browser), HTML/CSS Languages: English (fluent), Portuguese (Brazil & Europe), Spanish. Billing: I recommend milestone-based projects over hourly billing. This ensures cost predictability for clients and delivery clarity for developers — pay for tangible results, not just time. Message me to go from idea to execution — fast, clean, and future-proof. Mike Niner Bravog Agentics / DevOps / LLMs / CI/CD / Automation / NLP
