Hi, I'm Nathan Marley

I'm a backend-leaning full-stack software engineer with 15+ years of experience. I've led projects, refactored legacy systems, optimized performance, and helped teams ship faster with fewer headaches.

I specialize in:

  • LLM integrations, RAG pipelines, and structured OpenAI/Claude/Grok/Gemini tooling
  • Rapid MVP prototyping and full-stack product spikes using React, Next.js, Tailwind, and modern frontend tooling
  • Building backend services in Rust, Go, Python and TypeScript (w/Bun)
  • Designing and refactoring internal tools and dev infrastructure
  • Pragmatic cloud-native architecture on AWS

I work well with small teams and founders. Whether it’s fixing brittle systems, untangling technical debt, or shipping something new – I bring clarity, structure, and velocity.

Available for Hire

As of June 2025, I’m currently open to:

  • Full-time roles
  • Short-term contracts
  • Architecture reviews
  • Advisory engagements

If you’ve got a problem you want to untangle – I can help figure it out!

Portfolio

Here are a few things I’ve built recently:

  • HeySpeakeasy
    A macOS push-to-talk transcription tool that inserts your speech directly into any text field. Built with Swift and Whisper API – lightning-fast and seamless for prompt-driven workflows.

  • ShipMind (under construction)
    A context-aware personal agent that wraps LLMs in memory, context, and tool execution layers. Built in Rust, Python, TypeScript, and Postgres. Handles chunking, embedding, search, structured prompts, and agentic loops.

  • Glowberry Labs
    My solo consultancy – I help companies simplify infrastructure, modernize backend systems, and integrate LLMs into internal workflows.

Some Things I’ve Written

A few selected posts:

These focus on building high-performance systems – concurrency, I/O, and search.
More LLM-focused posts are coming soon.

Outside of Code

I live on a farm in Missouri with my family. I tinker with Raspberry Pi and electronics, plant trees, and build little tools for fun. I like old-school 2d pixel-art games, cryptocurrency, Linux, and strategy and have interest in robotics and learning languages. Love traveling and healthy living as well!

I’ve trained as a raw vegan chef, lived in Brazil for five years w/my family, and speak Portuguese and Luxembourgish. If any of these topics are interesting to you, please get in touch!

I’m interested in learning just about everything I don’t understand well or haven’t worked closely with yet. That includes fintech, payroll/HR, edtech, construction homesteading, and expat life.
