I specialize in Next.js, TypeScript, Supabase, and Node.js/NestJS, and I've led full-cycle development (architecture, implementation, QA, documentation, and delivery) across startups, agencies, and direct client engagements. Recent work includes translating a patented Excel-based financial valuation model into a full-scale, real-time calculation engine, migrations of legacy and no-code systems (Bubble, Xamarin) into modern full-stack platforms, and multi-tenant systems with optimized SOAP/REST APIs handling high-volume data at scale. My current focus is AI systems engineering, specifically designing persistent-memory architectures for LLM-powered applications. I've built a reusable "shared brain" pattern: a session-logging and knowledge-continuity layer that lets AI systems retain context across sessions instead of losing it when a conversation ends. I've deployed this architecture across multiple client environments, including a HIPAA-aware AI health companion (NestJS, Azure AI Foundry agents, WebSocket streaming, per-tenant vector stores, Prisma multi-tenant data layer, automatic escalation to human care teams) and internal automation tooling for business operations. The pattern generalizes beyond dev environments to any workflow needing durable, structured memory, including customer support, ops, or knowledge management. Beyond hands-on engineering, I mentor developers, maintain technical standards, and keep delivery aligned with business goals and timelines. I'm looking for a stable, growth-oriented team where I can keep building high-impact products and contribute long term to a shared vision. ## Skills ### [Project Management](https://jobicy.com/talent/project-management.md)[Python](https://jobicy.com/talent/python.md)[JavaScript](https://jobicy.com/talent/javascript.md)[React](https://jobicy.com/talent/react.md)[TypeScript](https://jobicy.com/talent/typescript.md)[Machine Learning](https://jobicy.com/talent/machine-learning.md)[Git](https://jobicy.com/talent/git.md)[C++](https://jobicy.com/talent/c-plus-plus.md)[MySQL](https://jobicy.com/talent/mysql.md)[Node](https://jobicy.com/talent/node.md)[MongoDB](https://jobicy.com/talent/mongodb.md)[Azure DevOps](https://jobicy.com/talent/azure-devops.md)[Next.js](https://jobicy.com/talent/next-js.md)[HTML5](https://jobicy.com/talent/html5.md)[CSS3](https://jobicy.com/talent/css3.md)[OOP](https://jobicy.com/talent/oop.md)[Firebase](https://jobicy.com/talent/firebase.md)[Backend](https://jobicy.com/talent/backend.md)[NestJS](https://jobicy.com/talent/nestjs.md)[Prisma](https://jobicy.com/talent/prisma.md)[Frontend](https://jobicy.com/talent/frontend.md)[SoapUI](https://jobicy.com/talent/soapui.md)[Software Project Management](https://jobicy.com/talent/software-project-management.md)[C#](https://jobicy.com/talent/c-sharp.md)[C](https://jobicy.com/talent/c.md) ## Education Instituto Politécnico de Bragança (IPB) Sep 2024 - Sep 2027 Bachelor's Degree in Computer Engineering ThreeJS Journey Feb 2022 - Feb 2023 Course Online course.
