Senior Platform Engineer | Embedded Systems & Agentic AI Infrastructure
Portugal (open to relocation) • LinkedIn • X
Self-taught Senior Platform Engineer with 9+ years building reliable systems across embedded hardware, distributed platforms, and modern agentic AI infrastructure. Former CTO & co-founder of a deep-tech energy storage startup (Prometheon Technologies) with multiple patents in proton battery systems.
I specialize in designing and shipping production-grade components that span constraints: resource-efficient embedded libraries, high-performance Go systems, and secure, memory-aware agent runtimes. I care about first-principles architecture, clean abstractions, observability, and building things that actually work in the real world.
Embedded & IoT Systems
C/C++, ESP32/Arduino, firmware development, networking stacks, OTA, sensor integration, reusable hardware abstraction libraries.
Platform & Systems Engineering
Go (systems, CLIs, backends), Linux (self-hosting, desktop infra, reproducibility), CI/CD, developer tooling, distributed systems patterns.
Agentic AI Infrastructure
MCP ecosystem, custom agent runtimes, tiered/persistent memory systems, capability-based security, context management, local-first & edge deployment.
Additional
Performance optimization, security boundaries, modular library design, documentation & production practices (ADRs, codegen, testing, CI).
DragonScale - Compact, secure AI agent runtime for Linux and embedded
Architected a production-oriented agent platform with capability-based tool isolation (SecureBus), DAG-parallel execution, MemGPT-style multi-tier memory with semantic projection, libSQL vector + FTS search, encrypted secrets, and multi-channel support. Single-binary, low-footprint design with strong engineering practices (ADRs, code generation, evaluation harness, CI). Focused on reliability and real deployment constraints.
mcp-memory-libsql-go - High-performance persistent memory server for the Model Context Protocol
Delivered a full Go implementation (with major enhancements) of an MCP memory backend featuring vector search, hybrid semantic + full-text retrieval, knowledge graphs, multi-project isolation, and embeddability as a library. Achieved 2× performance and 40% lower memory footprint versus the original TypeScript version through native execution and efficient driver usage. Includes metrics, fuzzing, and structured internals.
EasyNetworkManager - Reusable networking library for ESP32/ESP8266
Built and actively maintain a modular, production-adopted library providing Wi-Fi management (auto-connect + AP fallback), OTA (standard + async), mDNS, async REST/JSON API + WebSockets, and extensible configuration. Clean class design with extension points. Adopted in the open-source EyeTrackVR/OpenIris VR eye-tracking platform.
Other notable work: Geometric/point-cloud IMU drift correction (circlejerk), opinionated reproducible Linux desktop environments, GNOME workflow extensions, and various systems tooling.
- Senior Platform Engineer - Ownership of internal platform tooling, CI/CD, virtualization infrastructure, and cross-functional embedded firmware collaboration.
- CTO & Co-founder @ Prometheon Technologies (2019-2025) - Led deep-tech energy storage development (proton batteries). Multiple patents (WO2023166219A1, WO2024184244A1). Full-stack hardware/software systems in a startup environment.
- Prior experience includes roles at Gitpod and Emissium Labs, plus extensive open-source building.

- Advancing DragonScale - pushing the agent runtime toward more robust multi-agent coordination, skill graphs, and secure local deployment.
- Exploring practical applications of persistent semantic memory and MCP tooling for reliable agentic systems.
- Building tools and infrastructure that improve developer velocity and system reliability (self-hosting, automation, workflow).
I'm always interested in thoughtful conversations about platform engineering, embedded systems, agentic infrastructure, or deep-tech hardware/software co-design.
Open to senior opportunities in platform engineering, embedded/firmware systems, or AI infrastructure roles (Portugal base with flexibility for the right fit).
