<p class="blurb">Working across the architecture, observability, AI, and reliability of an FCA-regulated mortgage platform handling ~1.7M requests and 500K+ background jobs a day across 8 services. <span class="stack">Ruby, Rails, PostgreSQL, Redis, Sidekiq, AWS, Bedrock, NewRelic, Sentry, Docker.</span></p>
<ul class="bullets">
<li>Built and productionised a <b>unified case-management tool</b> that replaced the 22 separate systems mortgage brokers consulted per case with one centralised workflow, cutting case-handling time from <b>~65 minutes to ~10 minutes</b> so brokers can advise applicants live on a call — designed to double mortgage capacity without added headcount.</li>
<li>Engineered <b>AI bank-statement analysis on AWS Bedrock</b> to extract income and risk signals from PDF statements for mortgage fact-finding, solving a token-limit failure that silently dropped transactions and contributing the Bedrock provider upstream to the <a href="https://github.com/activeagents/activeagent">ActiveAgent</a> open-source project.</li>
<li>Leading a <b>third-party integration</b> that automates lender application submission so brokers stop re-keying data by hand, owning it end to end from partner evaluation and mapping 1,100+ data fields through to the build.</li>
<li>Established <b>platform observability from scratch</b> with six NewRelic dashboards, including the board-level OKR instrument the company steers by, surfacing systemic issues such as an integration at ~40% success generating ~17,000 dead background jobs a week.</li>
<li>Diagnosed and recovered a <b>partner sync silently broken for a month</b>, re-architecting it to per-user fan-out with retry resilience and landing the first clean overnight run at 14,213 users.</li>
<li>Set architecture direction through a full platform review, cut the <b>deployment pipeline from ~2 hours to 35 minutes</b>, and upgraded Ruby 3.2 to 3.4 ahead of EOL.</li>
