I am a senior systems engineer with over 15 years of experience, driven by a “UNIX systems and network programmer at heart” philosophy. I specialize in bridging the gap between low-level systems engineering and modern AI/LLM stacks.

I am generally open to strategic consulting and hands-on implementation for organizations that value security, privacy, and technical sovereignty.

Looking for a technical partner? The best way to start is by sending an email to consulting@blob42.xyz.

If there is a fit, we can schedule a call to discuss your needs.

AI / LLM Operations

This is my primary current focus. I help organizations move away from vendor lock-in by building private, on-premise AI infrastructure.

• Private AI Clouds: Architecture and deployment of air-gap-ready LLM stacks (Llama.cpp, vLLM, LocalAI, …) with GPU acceleration.
• RAG Pipelines: End-to-end optimization of Retrieval Augmented Generation, from embedding model selection to chunking tuning and vector DB (ChromaDB) integration.
• Agentic Systems: Design and implementation of autonomous agents using LangChain, N8N, and custom MCP servers.
• Custom Tooling: Development of specialized LLM proxies, debugging tools, and integration layers for existing enterprise systems.

Systems Programming & DevOps

My foundation is in high-performance, resource-efficient systems. I bring a security-first mindset to every layer of the stack.

• Languages: Expert-level implementation in Go and Rust for performance-critical applications.
• Infrastructure: SRE and DevOps expertise in Linux internals, complex networking (TCP/IP, routing), and containerization (Docker, Podman).
• Hardening: Security-focused deployments, SSO/LDAP integration, and air-gap architecture.
• Modernization: Migrating legacy systems to modern, maintainable IaC and containerized environments.

Specialized Tooling & Hardware

Beyond core systems engineering, I bring deep expertise in developer experience and a strong interest in hardware:

• Developer Tooling: Expert in building and optimizing high-efficiency developer workflows, specifically around Neovim, LSP, and Tree-sitter.
• Embedded Systems: While primarily a hobbyist (KiCad, Arduino/ARM/ESP), I have sufficient comfort and experience to collaborate effectively with teams working in embedded systems.

Open Source

I am an active OSS contributor and maintainer (134+ repos). I believe in a “fix-it” mentality—if a tool is broken, I patch it.

If you rely on projects I maintain (such as gosuki or Instrukt) or projects I contribute to (like LocalAI or LangChain), we can discuss:

• Retainer-style arrangements for continued maintenance.
• Implementation of specific high-priority features.
• Strategic influence over the project’s direction.

Blockchain & Cryptography

I have deep protocol-level knowledge of the Bitcoin ecosystem and decentralized communication.

• Bitcoin Core: Deep understanding of consensus, cript, and Taproot.
• Lightning Network: Implementation and management of LND/c-lightning.
• Nostr: Integration of the Nostr protocol and ZAP.
