Technical direction, code review, product delivery, and execution support for small teams that need senior help before, beside, or instead of a full-time hire.
Fractional staff engineer for AI, SaaS, and operational software.
I help small teams ship practical software, AI workflows, SaaS features, automation, and infrastructure fixes, whether as a full-time senior engineer or fractional technical lead.
Most useful when the work crosses product code, backend systems, hosting, and real operational constraints.
Focused web apps, SaaS features, automation, dashboards, integrations, and internal tools.
Hosting, CI/CD, observability, network troubleshooting, AWS deployments, and reliability work.
Current Work
2020 - PresentENG Aviation
Senior Software Engineer
Build the AI and operations platform behind a private-aviation SaaS, focused on pilot safety, flight scheduling, and the regulatory workflows that surround them.
- Built the pilot training and currency system end-to-end. It alerts flight operations when training is due or when pilots need additional flights to stay current, and it shows coordinators which pilots will actually be available, and still qualified, at the time of a planned trip.
- Built an AI-augmented trip-request pipeline on LangChain that reads inbound customer emails, checks pilot and aircraft availability, drafts quotes, and routes them to the flight operations center for review before they go to customers.
- Made the assistant useful on long conversations and grounded it in each customer's own data, so answers stay accurate as conversations grow.
- Built the eSecure export that submits passenger lists for TSA screening and tracks passenger clearance, saving flight coordinators 30+ hours per year that had been spent manually formatting files.
- Used LLM vision to read cockpit and flight-log photos, then prefill most of the flight log for pilots.
- Delivered scheduling and pricing features, including drag-and-drop reordering of trip legs and pricing, schedule-conflict detection, and a demo-data system used for sales and conferences.
SammyD LLC
Owner and Principal Developer
Independent consultancy delivering custom software and cybersecurity training platforms.
- Designed and shipped a TEA-compliant cybersecurity curriculum platform delivered to multiple Texas high schools, with interactive content, video integration, and automated assessment.
- Built browser-accessible cloud lab environments on AWS where students can safely study malware in isolated networks.
- Created hands-on training environments for threat analysis with strong safety boundaries between students and the systems they study.
- Contracted with Coherent Cyber to build an e-learning platform for cybersecurity instruction.

Botisimo / OpTic Gaming
Software Engineer
Built the multi-platform streaming, engagement, and aggregated-ad-revenue systems behind Botisimo, a creator tools platform for live streamers that was acquired by OpTic Gaming in 2023.
- Built the multi-platform streaming engine that let creators broadcast simultaneously to Twitch, YouTube, Facebook, Discord, and Trovo, with a chat relay so viewers on every platform could see and respond to each other in one shared conversation.
- Built giveaways, raffles, polls, and viewer rewards that worked across every connected platform, plus a rules engine for schedules, timers, auto-bans, and auto-replies, with AI-driven bot responses added as LLMs matured.
- Built the analytics and ad-targeting work behind an aggregated-audience ad product that pooled viewers across thousands of small streams into a single buy, giving creators who were too small to sell their own ads a real share of ad revenue.
- Built customer analytics and marketing data pipelines that informed product and growth decisions across the platform.
