Tech Lead · Senior AI Engineerbuilding agent platforms in SaaS

I build and orchestrate multi-agent AI systems. Ten-plus years shipping full-stack platforms across SaaS, fintech and enterprise — now designing the agent runtimes, MCP tool servers and RAG pipelines that put them into production.

Who is
writing this

Engineer first.
Architect by necessity.
Tech lead by choice.

I've spent ten years building the web platforms companies actually run on — CRM and marketing automation for small businesses, member eligibility at USAA, payment flows at PayPal. Front-end architecture is where I'm deepest: React, Vue 3, TypeScript, and the build systems and component libraries that decide whether a team of engineers ships weekly or monthly.

For the last two years that work has pointed squarely at AI. I architected and shipped a Python agent orchestration service — a multi-tenant API where internal product teams register, configure and run their own LLM agents — replacing the per-team one-off integrations that came before it. Around it I built MCP tool servers, a memory RAG pipeline on a vector database, and the in-product AI chat experience end to end.

I lead onshore and offshore engineers from architecture through Kubernetes deployment, and I care a great deal about the unglamorous half: distributed tracing, instrumentation, build times, and removing the duplicated code that quietly slows everyone down.

Senior Software Engineer (Tech Lead)

SaaS CRM & Marketing Automation Platform — company named on request
  • Architected and shipped a Python agent orchestration service — a multi-tenant API where internal product teams register, configure and run their own LLM agents — replacing per-team one-off integrations across a CRM and marketing-automation platform used by small businesses.
  • Built Model Context Protocol (MCP) tool servers giving agents access to product data and internal APIs, cutting new AI integration effort from weeks to days.
  • Designed a memory RAG pipeline on a vector database that grounds agent responses in company data, and delivered the in-product AI chat experience end to end — streaming responses, conversation state, retry and fallback handling — in Vue 3 and React.
  • Own front-end architecture platform-wide: drove the Webpack-to-Vite migration and a shared Vue and React component library that cut CI build times ~30% and removed ~40% of duplicated UI code.
  • Lead and mentor onshore and offshore engineers; introduced distributed tracing and Datadog instrumentation that cut time to diagnose cross-service faults ~35%.

Senior Software Engineer

USAA
  • Built and shipped a React and TypeScript eligibility platform determining member qualification for USAA banking and insurance products, serving a member base in the millions.
  • Implemented route-level code splitting with React Router, reducing initial bundle size 15% and improving first contentful paint.
  • Architected Redux state management for a multi-step SPA and a reusable component system in JSX and SCSS, standardising data flow across feature teams and eliminating a recurring class of state-sync defects.
  • Partnered with backend engineers on REST contract design and deployed through GitLab CI to AWS with Docker and Kubernetes in two-week Agile sprints.

PayPal Inc.
  • Built single-page payment-flow front ends in React and Redux with action-based store updates, plus JWT authorisation and Node.js data-exchange layers between clients and backend services.
  • Established the production build pipeline — Webpack, Babel, Sass — and raised release confidence with Jest, Enzyme, Selenium and TestNG suites, increasing coverage to 97%.

Things I built
and shipped

01 / AI PLATFORM

Agent Orchestration Service

A multi-tenant Python API where internal product teams register, configure and run their own LLM agents — replacing the per-team one-off integrations that came before it across a CRM and marketing-automation platform.

02 / TOOLING

MCP Tool Servers

Model Context Protocol servers giving agents governed access to product data and internal APIs. Cut the effort to add a new AI integration from weeks to days.

03 / RETRIEVAL

Memory RAG Pipeline

A retrieval pipeline on a vector database that grounds agent responses in company data — embeddings, retrieval and conversation memory, so answers cite the business rather than the model's priors.

04 / PRODUCT

In-Product AI Chat

The end-to-end chat experience: streaming responses, conversation state, retry and fallback handling — built in Vue 3 and React against the orchestration service.

Front-End Platform & Vite Migration

Platform-wide front-end architecture — a shared Vue and React component library plus the Webpack-to-Vite migration. Cut CI build times ~30% and removed ~40% of duplicated UI code.
