🥇 Top Rated on Upwork | 5+ Years Delivering Production Systems AI Orchestration • Agentic Systems • AI Ops • Automation Architecture I architect and orchestrate production-grade AI systems. In 2026, writing code is no longer the bottleneck. Orchestration is. My work focuses on designing modular infrastructures where AI agents, automation pipelines, and scalable systems operate reliably, transparently, and under control. I build execution environments where LLMs, vector databases, automation engines, and backend services work together as structured components, not experiments. What I Actually Do • Architect multi-agent AI systems with clear execution boundaries • Design RAG infrastructures with embeddings, retrieval, and evaluation layers • Build AI orchestration pipelines, local or cloud-agnostic • Implement AI Ops workflows including monitoring, logging, evaluation, and rollback strategies • Structure data ingestion pipelines for scraping, parsing, normalization, and indexing • Convert unstructured knowledge into vectorized, queryable systems • Deploy local LLM infrastructures that are GPU-aware, measurable, and self-hosted • Integrate APIs, webhooks, and event-driven architectures • Create deterministic automation flows in Bash and Python where AI acts as an executor • Implement CI/CD and reproducible AI deployment environments • Engineer Linux-first, infrastructure-controlled AI stacks Approach AI writes code. I design the system that determines what AI should build, how it should be deployed, how it should be measured, and how it should recover when things fail. No black-box SaaS dependency. No fragile no-code dashboards. No hype-driven stacks. Modular components. Observable execution. Reproducible deployments. Auditable AI behavior. I Prioritize • Orchestration over raw coding • Measurable inference over demos • Infrastructure over UI polish • Control over abstraction Core Stack (AI-Centric) Python • Bash • FastAPI • Docker • Redis PostgreSQL • Vector Databases (Pinecone, Chroma) OpenAI • Cohere • Local LLMs (GPU / Self-Hosted) Debian Linux • Git • CI/CD • systemd Legacy & Extended Experience PHP (Core, Procedural, Shell-Integrated) Perl (Sysadmin, Automation) JavaScript (Node.js and Browser) HTML/CSS Languages English (Fluent) Portuguese (Brazil & Portugal) Spanish Billing Philosophy Milestone-based delivery. You pay for infrastructure that is delivered, tested, and validated, not for hours consumed. If you need AI systems that actually run in production, not just prompts, let's build them properly. Mike Niner Bravog AI Orchestration • Agentic Systems • AI Ops • Infrastructure Automation

I build code-first AI workflow automation systems using Python, OpenAI and Anthropic APIs, and Google Apps Script and Microsoft VBA. My work focuses on document processing, data extraction, Google Sheets / Docs automation, and structured business workflows that need to be reliable, maintainable, and usable by real teams. Clients usually bring me in when an automation is partly working but too fragile to trust. I tighten business logic, improve extraction quality, add review checkpoints and logging, and turn manual processes into systems a team can actually operate. Typical delivery includes Python scripts, Flask web apps, API integrations, Google Sheets with Apps Script, and deployed workflow systems. I bring enterprise product and delivery experience from Nike and Momentive (SurveyMonkey), which helps when a project needs requirements clarity and stakeholder coordination alongside hands-on implementation. Recent projects include: - Python/Flask web app for document processing and healthcare workflows, including lab-report PDF analysis, multi-step AI orchestration, staged prompts, markdown handoffs between agents, and DigitalOcean deployment - Long-running Python/Flask application for a psychologist with multiple clinics in California, processing large volumes of client test data. It performs longitudinal statistical analysis with charts, generates patient-friendly results in the patient's native language, and automates final formatting in Microsoft Word using the psychologist's preferred templates and styles - Google Sheets / Docs automation with AI-generated document outputs and workflow logic - Prompt engineering and ChatGPT process automation for an ongoing client - Debugging and stabilizing an existing team's workflow mid-project On Upwork, I’m Expert-Vetted with 100% Job Success, $300K+ earned, and 41 completed contracts.
