I keep business infrastructure running and secure, and build the software that makes it run better.
The systems I run and answer for every day, across multiple buildings and client environments.
We provide internet service to customers across multiple buildings on a network we run ourselves. I manage the routing, switching and access points it's built on, keep it up, and support the customers who depend on it.
Onboarding and offboarding, licensing, Exchange mailboxes, Teams, SharePoint and OneDrive, MFA and the access policies that decide who gets in, all run through the Microsoft 365 admin center across multiple tenants.
A Grandstream PBX: extensions, ring groups, auto attendants and call routing, SIP trunks to the carrier, desk-phone provisioning, and tracking down call-quality problems before customers notice them.
Remote support, hardware and software troubleshooting and clear documentation for 100+ users. Behind the tickets: monitoring and SIEM alerts, risk assessment, access-control enforcement and incident response.
Software I've designed and shipped to make those operations run better.
We were paying a monthly subscription for a commercial ISP billing and operations suite built for everyone. I rebuilt the parts we actually use, tailored to how our team works: every customer, quote, hour and invoice now lives in one system we own.
Quotes become jobs, time logged against a job flows into both the customer's invoice and the employee's timesheet, and recurring service is billed without anyone re-entering it.
Subscription retiredA general-purpose subscription suite, paid monthly, that made the team work its way instead of ours.
Rebuild only what we use, around one customer record, with role-based access and an audit trail from day one.
No more re-entering hours between systems, invoices built from logged work, and no recurring licence fee.
A retrieval pipeline running the Qwen 14B model on our own hardware, with a Next.js interface and admin controls. Staff get cited answers from internal documents in seconds, and nothing is sent to an outside AI service.
Wi-Fi planning in the browser: upload a floor plan, draw walls by material, place from 194 access-point models, then read live heatmaps, channel plans and coverage reports.
Source on GitHub ↗An offline-first training log that installs like a native app. React and strict TypeScript, IndexedDB storage, a service worker, Vitest and Playwright tests. No backend and no tracking.
Source on GitHub ↗Every build starts with a problem I hit at work. I use AI tools to move faster, and they sharpen my thinking: once something is live I'm already asking what could be better, what's missing and what to build next. It's a never-ending problem-solving loop, and it's the part of the job I enjoy most.
Every design decision, review and deployment is mine.
