I've spent 15 years building and leading engineering teams across startups, SMEs and corporates. I've also run the operations behind them: billing, bookkeeping, lending and reporting. The systems I build fit the way a business actually works.
Billing was worked out by hand: one to two people, two to three weeks, every run. I built a rules-based engine that works out what each customer is charged and runs on its own.
I led a team of eight. We brought in modern CI and infrastructure as code, split a legacy monolith so each app deploys on its own, and gave leadership a clear view of how long work would take. Deployments went from days to minutes.
I led an engineering team of seven across three streams to rebuild the CoinJar platform for a nationwide payment network, letting people pay for goods and services with bitcoin in real time. That included CoinJar Swipe, a debit card that let people pay with bitcoin anywhere that accepted EFTPOS.
Loan origination, the lender portal, interest calculations, payment rails, a line of credit, and the Xero integration that keeps the loan system and the ledger in agreement. Externally audited.
I coordinate multiple AI agents working in parallel to build systems.
I use AWS Bedrock to keep critical data sandboxed and easily plug into existing workflows and applications.
Rapid prototyping, mockups and design systems.
Within a handful of weeks the team had turned around. Aron assisted in the hiring of new developers and was hands on in every aspect of the dev team that needed assistance.
Aron joined the company early on, during a period of significant growth, and swiftly implemented tools and processes. Outages and downtime became all but obsolete under Aron's lead.
Aron's ability to speak at a deeply technical level with client IT resources is valuable in complex and ambiguous technical environments, and he consistently translates this for non-technical clients.
As a leader Aron has made me question my approach to programming as well as work life and has truly been an inspiration to strive for excellence.
