I build AI systems for real product environments: agents, automation workflows, backend platforms, integrations, and governance tools for teams that want to use AI without losing technical control.

I currently work as a freelance / independent builder through Ptech Solution, helping companies, founders, and technical teams design, build, and ship backend and AI systems with a clear architectural foundation.

I am repositioning my work around AI Systems Architecture: not just building AI features, but designing complete systems where models, data, prompts, tools, backend services, security, cost, and operations work as one coherent architecture.

Current focus:

• backend systems with AI embedded into real workflows;
• agents and automation for operational use cases;
• RAG, tool use, workflow orchestration, and evaluation-aware design;
• integrations with Microsoft 365, WhatsApp Business API, internal APIs, and CRMs;
• governance for AI-assisted software development;
• own products, internal frameworks, and open source tools.

I work independently through Ptech Solution.

I focus on projects where architecture matters, not only implementation:

• AI system design for SaaS, internal operations, and automation;
• backend platforms with Django, FastAPI, PostgreSQL, and structured APIs;
• complex integrations across tools, data, and business workflows;
• productizable prototypes with a clear technical roadmap;
• technical audits for AI products, automations, APIs, and backend systems.

My goal as a freelance builder is to help turn unclear ideas or messy processes into maintainable, governable systems that can evolve.

This section will grow as I publish frameworks, tools, and utilities.

Specification-first governance for AI-assisted software engineering.

PSDM is a framework for governing software projects built with AI assistance. It helps teams and AI agents classify change risk, maintain specifications, document architecture decisions, review security/data/AI concerns, and apply delivery controls based on change impact.

Status: 1.0.0-beta.1
Format: Local CLI + GitHub Action
Stack: Node.js · JSON contracts · GitHub Actions · governance templates
Repository: github.com/pablotech80/psdm-framework

AI writes code. PSDM governs it.

AI systems: agents, RAG, LangChain, LangSmith, tool orchestration, prompt governance, evaluation-aware workflows.
Backend platforms: Django, FastAPI, PostgreSQL, SQL, GDB, API-first design, modular systems.
Automation: n8n, Microsoft Graph, WhatsApp Business API, internal workflows.
Cloud & delivery: Azure, AWS, Google Cloud, Vercel, Hetzner VPS, Docker, GitHub Actions.
Observability & workflow: Datadog, Linear, delivery tracking, operational feedback loops.
Governance: specifications, ADRs, Scrum delivery, risk classification, release gates, security boundaries.
Product work: published and maintained through ptechsolution.net.

Building AI systems, automation frameworks, and open-source tools for software teams that need speed with control.
