Software engineer & engineering leader

I build the software and lead the teams that ship it.

Hands-on across full-stack product development, AI systems, APIs, performance, and delivery. I bring 20+ years of engineering experience and the judgment to turn ambiguous product needs into reliable customer-facing software.

What I bring

Technical depth, product judgment, and accountable delivery.

I am strongest where technical ambiguity and customer urgency meet: turning a rough product need into an architecture, a working system, and a release the team can support with confidence.

Engineering & architecture

Full-stack applications, AI and LLM systems, APIs, data workflows, performance work, and production troubleshooting. I make pragmatic tradeoffs around reliability, observability, security, cost, and user experience.

TypeScript · JavaScript · Python · React · Next.js · Node.js · SQL · GraphQL · Redis · Databricks

Leadership & delivery

Hiring, coaching, technical direction, quality practices, release discipline, and product partnership. I help teams move faster by making scope, ownership, and engineering standards clear.

AI systems · RAG · Agents · MCP · AWS · GCP · CI/CD · Test automation · Observability

Selected experience

Technical ownership at product, platform, and team scale.

I have held engineering, management, and founder roles. The common thread is shipping useful software where product urgency, system quality, and delivery accountability meet.

More on how I lead and deliver
  1. Nov 2023 – Nov 2026

    Blackbird.AI

    Principal Software Engineer → Senior Engineering Manager → Director of Engineering

    Led App Platform engineering and QA while continuing to build production AI capabilities. Improved Narrative Page loads by up to 45% and reduced a difficult SQL query from 4 seconds to 788 milliseconds through API batching, Redis caching, Databricks investigation, and monitoring.

  2. 2022 – 2023

    You.com & Dispatch

    Engineering Manager

    Led teams delivering AI search and Web3 messaging products, pairing practical architecture and hands-on engineering work with planning, quality, release discipline, and cross-functional delivery.

  3. 2015 – 2022

    Experian

    Manager of Innovation

    Built fraud detection, credit-risk, API, mobile, and cloud-native product initiatives across data platforms, machine learning, and customer-facing software.

  4. 2006 – 2017

    Weber LLC

    Founder & product engineer

    Delivered 40+ web and mobile applications across SaaS, ecommerce, media, AI-assisted consumer products, and rapid-response utility tools.

How I work

Principles for building software that holds up in production.

Engineering Operating Systems

I make ownership, planning, quality, and delivery visible enough that teams can move quickly without relying on heroics.

Clear operating rhythms, better scoping, automated checks, and accountable handoffs help teams scale output before adding headcount.

Production AI Systems

I treat AI as software that has to be reliable, observable, secure, and economically defensible.

The work is not just model selection. It is evaluation, workflow design, cost control, monitoring, security review, and human-centered product judgment.

Product-Engineering Partnership

I connect technical decisions to customer urgency, revenue, adoption, and trust.

Strong product partnership keeps architecture, roadmap tradeoffs, security constraints, and delivery pressure pointed at the same business outcome.

Reliability, Security, and Delivery

I push for speed with discipline: stronger quality gates, tighter release habits, and pragmatic security judgment.

Teams earn speed by reducing ambiguity, catching defects earlier, and making customer-impacting risk explicit before it reaches production.
