Delivering modern products with a calm, detail-obsessed approach.

Leading development and launch of the anythingsupplies.com and sals3.com e-commerce platforms for Anything Supplies Pty Ltd (Australia), directly managing a team of 4 developers.

• Led the development and on-schedule launch of anythingsupplies.com and sals3.com, directly managing a team of 4 developers in Agile (daily stand-ups, two-week sprints, and a ClickUp board with burndown and velocity charts).
• Designed a full-stack infrastructure with Cloudflare edge caching and security, automated CI/CD pipelines, and system monitoring for high availability, fast page loads, and smooth deployments.
• Enforced automated merge-request review rules and added AI-assisted review (Claude and OpenAI) to speed up code reviews while keeping quality strict, building with an AI-accelerated workflow (Claude Code, Codex, Gemini) under git-based staging and QA.
• Highlights (September 2026): Replaced hand-published batches with an automated sourcing pipeline that publishes supplier products on a schedule with no manual steps, growing the sals3.com catalogue many times over in a few weeks and greatly improving automatic categorisation of the supplier catalogue.
• Highlights (September 2026): Launched two new country storefronts, sals3.com.fj (Fiji) and sals3.com.au (Australia), each with its own look, checkout, and currency, with the exchange rate locked on every order.
• Highlights (September 2026): Built a Gemini-powered Seller Center assistant in production that fills product specifications from photos and the supplier page, filling only what it can honestly answer.
• Highlights (September 2026): Added a free-delivery nudge that suggests add-ons to close the free-delivery gap, and built customer-support tools: buyer profiles, a 24-hour cancellation hold, and per-item refunds.
• Highlights (September 2026): Made the Seller Center product list much faster even as the catalogue grew, cut the largest usage-based hosting cost by fixing storefront traffic that skipped the cache, and patched a critical framework vulnerability on all three storefronts the same day it was found.
• Security (September 2026): Contained a large botnet attack on the anythingsupplies.com WooCommerce store by closing the exploited entry point at the source, putting the site behind Cloudflare's firewall, and locking the server 'back door' when the attack returned larger—blocking attack traffic before it reached the application and database so the homepage was fast again instead of timing out.
• Moved sals3.com behind Cloudflare and added browser security policies to every storefront.
• Roadmap: Phase 2 adds AliExpress as a second supplier plus Gemini automation for those listings; Phase 3 is a Sals3 mobile app for Android, iOS, and Huawei; Phase 4 adds a customer-service CRM and customer accounts.

Led technology strategy across core business platforms for Genz & Associates, LLC (genzassociates.com), an M&A advisory business.

• Managed development, testing, and releases of Target Select AI (TargetSelect, a custom AI-enabled research platform), and owned integration planning between Target Select AI, DealCloud (CRM), and Outreach (sales engagement).
• Monitored and controlled cloud infrastructure and API costs, investigated and resolved technical issues, coordinated vendors and internal stakeholders, improved data sync and automation workflows, wrote technical documentation and communication updates, and handled user access, platform administration, and system governance.
• Key initiative — Outreach ↔ DealCloud bi-directional sync launch (run with integration partner RevOptics): handled sandbox UAT and triage of field-sync failures (multi-select picklists, primary contact, off-by-one-day date sync, null-value sync), delivered field-mapping updates and new custom objects (Target object and fallout-quality fields), and configured business-development record layouts and smart views.
• Implemented trigger automations for the Outreach ↔ DealCloud sync: stage mirroring, call disposition to contact status, and email bounce to status / call-only sequence.
• Executed production migration, data exports, end-to-end record reconciliation (Account/Company, Prospect/Contact, Opportunity/Engagement), API redirect, bulk 'ghost update' re-imports, post-launch error monitoring, and enablement workshops for the BD team.
• Administered the firm's technology ecosystem: TargetSelect (custom AI-enabled research platform), Outreach.io (call and email sequencing, task management), DealCloud by Intapp (CRM customized for M&A), Google Cloud and Gemini (platform enablement, integration, and AI), GitHub, data and research sources (SourceScrub/Grata, ZoomInfo, ChatGPT, Claude), and office stack (Google Workspace, Zoom, Nextiva phones, company website, office internet, and printers).
