• Field

Promoted from IT Field Technician. 232 convenience and fuel sites across New England.

• Traced a site-wide wireless authentication failure across three vendor boundaries: the access-point vendor, a managed network provider, and the ISP. Every ticket had been closed as working as designed. Captured wireless and wired traffic, proved a 3,570-byte TLS certificate fragmenting on the third frame, and isolated an 8-byte MSS mismatch between the access-point VLAN and a WAN running a non-standard MTU. Validated the fix at two more sites, remediated the rest, and published the root-cause writeup.
• Built the retail support platform for the organization: 110 published documents, a 232-site operational database, and a 230-record device and cabling inventory on Docusaurus and Azure Static Web Apps. A technician types a site number and gets the documents that apply to that site's platform, or an instruction to escalate.
• Acting technical project manager for new-store openings: POS, fuel dispensers, VLAN design, and network turn-up against a launch date. Wrote the rack and structured-cabling standards for NTI/RR sites organization-wide.
• Standardized device labeling across the organization and built the rollout tooling: per-site label sheets generated as print-calibrated PDFs from the site database, with a guided checklist and a reporting path for non-standard equipment found on site.

• Seacoast, NH
• Remote

Sole technical owner for WrapUSA Industries, a multi-million-revenue importer and distributor of moving and material-handling supplies with no internal IT. Every decision has to be maintainable by a non-technical team.

• Built Palace, the CRM and project platform the client now runs their business on daily. React 19, Hono, and TypeScript on Cloudflare Workers with Postgres, authenticated through Cloudflare Access with row-level security. Replaced two paid SaaS products and the lock-in with them.
• Built the agent surface on top of it, in production for a paying client. One route factory mounted twice, once for humans and once for machines, so both paths share a single implementation. A scope grammar validated at mint and again on every request, failing closed. Hash-only machine keys, each bound to its own machine actor, so every agent write is attributed to a specific key rather than to a shared service account. Append-only audit. A documented human-in-the-loop seam where a proposal stops and waits.
• Launched wrapusaindustries.com on Astro and Cloudflare Pages with GitHub Actions CI/CD. 73 products across 8 categories, a cart-style quote-request flow, Resend delivery, Turnstile and origin allowlisting on every endpoint. The content schema validates at build time, so a malformed catalog entry fails the build instead of reaching a customer.
• Turned 18 Chinese-language manufacturer spec sheets into a 142-SKU structured product model with a decodable part-number taxonomy and a duty-based category system buyers search by.
• Migrated the client off an unmaintained Microsoft 365 tenant to Google Workspace and put the stack behind Cloudflare Zero Trust with Google SSO. Still administer identity, groups, shared inboxes, onboarding, and Bitwarden.

• Dover, NH

• Specified and deployed connected sensor and monitoring upgrades on production machinery. On call for equipment failures through pandemic-era volume scaling.
• Rewrote equipment manuals and SOPs into standardized operator training material.

• Dover, NH

• Tier 1 support. Authored knowledge-base articles that replaced unusable vendor documentation and closed out recurring ticket types.
