What we build

From the sensor on the floor to the model in the cloud.

Most shops do one of these. Expert Coders does the whole stack, so the hardware, the backend, and the AI layer are designed by the same person.

Custom web applications
Full-stack Python with Flask, Django, and PostgreSQL. Internal tools, customer portals, admin dashboards, and API backends built to your spec.
AI agents and LLM systems
Autonomous agents with retrieval, vector databases, and semantic search. Systems that reason over your documents and plug into the tools you already use.
IoT and embedded systems
ESP32, Arduino, and real-time sensor integration. Industrial monitoring, paint booth systems, conveyor counting, and the GeoSpect instrumentation platform.
SCADA and data acquisition
Process monitoring and control. WITS protocol streaming, pressure cycling automation, and chromatography integration for industrial sites.
Data mining and web scraping
High-volume extraction with proxy rotation and fault tolerance. Government procurement portals, financial data, legal leads, and competitive intelligence.
Privacy-preserving AI
Split inference that keeps sensitive data on your hardware while borrowing cloud compute. Powerful models without exposing proprietary information.
Mobile apps
Cross-platform iOS and Android apps with Flutter and Capacitor, wired into your APIs and existing web systems.

How we execute

Scope fast, build in the open, own the result.

Pick a time that works →

Clarify scope fast
We define the technical objective, the constraints, and what success looks like before any code is written, so execution stays focused.
Build and iterate
Continuous progress with regular updates and working checkpoints you can click on, not slide decks about progress.
Own the outcome
Proactive risk flags, practical tradeoffs, and production-minded implementation from day one through support.

Why Expert Coders

A business owner who happens to write excellent code.

Sixteen years running a multi-state company means I understand deadlines, stakeholders, P&L impact, and what "done" actually means. I think about your business goals, not just the code.

I bridge physical systems and software. IoT sensors, industrial protocols, embedded devices, and web platforms, all from one developer. I built and sold a complete hardware and software product, GeoSpect Instruments, so I know the lifecycle from prototype to production to support.

"The software you built has made mud logging less stressful, enjoyable and flat out easy!"Mud logging customer, drilling operations

No handholding required

Bootstrapped a company from nothing and delivered under pressure without being managed. Proactive communication, owned outcomes.

Published AI research

Original research on LLM inference, published on arXiv. The same rigor goes into every client project.

Hardware meets software

From a pressure transducer on a wellhead to a PostgreSQL schema to a Flutter app, one person designs the whole path.

Decades of field experience

Oil fields, manufacturing floors, legal offices, healthcare operations. Every project benefits from that perspective.

Full product builder

Prototype, production, packaging, support. GeoSpect went from a bench to paying customers.

Direct line

You call, I answer. No account manager, no ticket queue, no translation layer between you and the person writing the code.

Published research

Privacy-Aware Split Inference with Speculative Decoding for Large Language Models over Wide-Area Networks

A system for running large language models privately by splitting computation between trusted local hardware and untrusted cloud servers, reaching 8.7 to 9.3 tokens per second over real-world network conditions.
