Hello, I am

BENE#UR

Senior Full-Stack and AI Engineer · Tech Lead

From idea to production systems: AI and SaaS products that hold up in real use.

I work the full cycle: understand the problem, shape the experience, build frontend and APIs, model data, integrate services, and leave operations observable, secure, and easy to maintain.

Selected projects

  1. Engraving of a classical bust with orbits, planets, and collaboration scenes around it

    01 / AI · Agents · Multi-tenant

    AI agent platform

    Multi-tenant voice and chat agent platform with RAG, persistent memory, session management, tool execution, and MCP integrations, built at Orbital One Labs.

    Companies needed configurable agents in production, not isolated demos. The platform unified models, knowledge bases, sessions, lead capture, workflow automation, and distributed infrastructure with SOC 2-aligned controls.

    Technologies

    TypeScript / Fastify / PostgreSQL / Prisma / Redis / BullMQ / OpenAI / Claude / Gemini / MCP

  2. Engraving of a globe with orbits, a hand, and an eye, suggesting operational awareness and coordination

    02 / Aviation · Real time · Operations

    Operations Control Center

    Real-time platform to coordinate aircraft recovery and ground turnaround at Azul Linhas Aéreas Brasileiras: ramps, gates, boarding, and special assistance.

    Airline operations relied on fragmented views. The center brought ground status, departure milestones, catering, and internal chat onto a single surface.

    Technologies

  3. Engraving of logistics with Atlas carrying cargo, a mechanical eagle, a ship, and containers

    03 / Aviation · Logistics

    Air cargo management

    Cargo tracking, airport logistics, and pre-departure cargo completion platform, maintained and evolved at Azul.

    Cargo and ground flows needed reliable traceability and processing through flight close. The system supports tracking, workflows, and cargo completion.

  4. E-commerce engraving with a classical bust, coffee, KitKat, a cart, and checkout symbols

    04 / E-commerce · Enterprise

    Enterprise Magento commerce

    Adobe Commerce / Magento 2.4 storefronts for brands such as Starbucks At Home Brasil, KitKat, FTD Educação, Madeiranit, Broto, and Galderma.

    Purchase journeys, checkout, and payment integrations were breaking conversion. End-to-end customizations and diagnosis stabilized the critical flows.

path

Beyond what I build, how I think matters.

In startups I turn ambiguity into delivery: find the real problem, decide pragmatically, and build systems that can grow after the MVP. I work hands-on across frontend, backend, and platform, with an eye on experience and business outcome.

I take products from sketch to production with end-to-end care: requirements, UX, frontend, APIs, data, integrations, deploy, and security. Where I add the most value is at the intersection of AI and engineering: multi-tenant agents (voice and chat), RAG, memory, tools, and automation. Looking for on-site startup roles in Texas (USA). Open to remote when it is a good fit.
