An Empire of One

Ten years of load-bearing engineering, condensed to a single page.

About Me

A decade building trading, risk-management and enterprise software, across the JavaScript, .NET, Java and now C++ ecosystems: from Microsoft Teams to an Agency Trading Order Management System. I still write code on the weekends — the itch to learn never quite goes away.

Experience

2023 — PRESENT

Senior Software Engineer

Broadridge Trading and Connectivity Solutions

Core feature work on a risk management platform, back at the former Itiviti organization.

  • Deliver features end to end, from ambiguous business requirements through to release
  • Run front-line production support for client-facing systems, turning recurring incidents into product fixes
  • Integrate AI coding agents into day-to-day delivery, cutting time spent on routine implementation and test work
  • Mentored three interns over two years — all three converted to full-time engineers
  • Interview intern and full-time engineering candidates
  • Write automation coverage in a DSL-driven test framework; keep CI/CD code and pipelines healthy ahead of failures

Kotlin · Java · Groovy · OSGI · C++ · C#

2022 — 2023

Software Engineer

Microsoft (Remote)

Front-end engineering on the people surfaces of Microsoft Teams — at-mentions and the message editor, in front of hundreds of millions of users a month.

  • Shipped features across at-mentions and the message compose experience
  • Removed the cold start on the at-mention picker: up to ~3 seconds on first use, down to instant

TypeScript · React · ReactiveX

2019 — 2022

Software Engineer

Itiviti (now Broadridge)

Feature work across an agency trading order management system — the platform brokers use to route and manage client orders.

  • Delivered features end to end, from requirements through stakeholder demos
  • Extended FixATDL support in the Algo Management product — the FIX standard describing how algo order parameters are defined and rendered
  • Maintained the legacy WinForms single-stock trading product
  • Repaired and refactored the internal release-automation tool; reviewed code across teams
  • Mentored a summer intern; interviewed intern and full-time candidates

Java · Kotlin · Groovy · OSGI · C# · ReactiveX · WinForms · WPF · F# · React · TypeScript · Python

2018 — 2019

.NET (Full-Stack) Developer

Yonder

Built features for a medical application and a complex traceability solution.

  • Built rich, heavily customizable UIs and synchronization between systems
  • Reverse-engineered and migrated the legacy solution

Angular · .NET Stack · Active Directory / LDAP

2017 — 2018

.NET (Full-Stack) Developer

Bosch

Built a traceability & reporting tool supporting the V-Model development process used in Powertrain SW Engineering.

  • Introduced the team's code review process
  • Mentored an intern with no prior experience over six months, then two junior developers
  • Led large refactorings and modernizations of the codebase

C# · MSSQL · Entity Framework · OSLC · WCF · ASP.NET MVC · Active Directory / LDAP · IBM Rational

2016 — 2017

JavaScript & .NET Developer

Pentalog

JavaScript Developer on a legacy ExtJS enterprise app, then .NET Full-Stack Developer building a single-page application.
