I’m JD Sileo, a solo systems builder. For twenty years I’ve shipped custom internal tools, wired disparate business systems together, and modernized the networks and phones behind a 10-location, three-state retail and distribution operation — no agency, no bench, no account manager between you and the person doing the work.
Tell me what’s slowing your business down — I’ll show you what I’d automate first. Twenty years of experience, one builder, no runaround.
Here’s where I do my best work — from automation and custom software through infrastructure, telecom, and technology strategy. Every card links into the portfolio, so you can see the real projects behind each skill.
I build bespoke line-of-business software — mostly PHP and MySQL — that replaces rigid vendor platforms and the manual back-office work your staff does by hand: returns modules, claims and delivery-fee audits, digital assistants, and paperwork automation.
35 custom software & automation builds shipped — including a damage-claims automation system credited with recovering over $1M, an automated warehouse returns module, and digital coupon delivery cut to 2.5–6¢ each from 11¢ on paper.
I wire disparate business systems together over REST APIs and middleware so data flows automatically — POS to dispatch, service tickets to payment, corporate feeds to inventory — and your team stops reconciling spreadsheets between billing, field service, and stock.
25 integration projects, including a DispatchTrack order-sync connector and a payment-processing integration that applies customer payments to service tickets in real time.
I use ChatGPT, OpenAI Codex, and Claude Code as build accelerators to ship real production software faster — and I embed LLMs directly into business workflows where they earn their keep, not as a demo. Custom GPTs, MCP tooling, and multi-agent orchestration.
17 AI-assisted builds, including World of Statecraft — a redistricting engine spanning ~951,000 real-world jurisdictions on Laravel, PostGIS, and multi-agent orchestration.
I turn raw operational data from your POS, service, call, and asset systems into real-time, leadership-facing dashboards, KPI models, and performance rankings — so you’re managing off live numbers instead of last month’s export.
A Chart.js service dashboard visualizing ticket volume, scheduling, and agent performance live, plus a unified call board tracking talk-time across sales, service, and care teams — after which agent call performance climbed over 80%.
I design and run the networks behind multi-location operations — pfSense/UniFi firewalls, multi-WAN failover, structured cabling, Wi-Fi, and full store openings, renovations, and relocations — plus emergency disaster-recovery response when hardware dies.
31 infrastructure projects, including converting 12 locations from Fortinet FortiWANs to pfSense and building segmented guest and employee Wi-Fi on pfSense and UniFi.
I migrate and manage Microsoft 365, Exchange, Azure, and Google Cloud environments — Active Directory, MFA, and identity/access — and roll out SharePoint, Teams, and OneDrive plus the endpoint fleets your people actually work on.
Migrated 150+ users from on-prem Exchange 2007 to hosted Exchange 365 and stood up a data center on Microsoft Azure.
I move businesses off aging PBX platforms onto cloud-hosted 3CX, consolidate SIP trunks, and add Twilio SMS/MMS, AD-integrated click-to-call, and CDR reporting — usually driven by killing cost and improving reliability.
A cloud-hosted 3CX PBX conversion with AD-integrated click-to-call, plus a Verizon Wireless bill cut from nine lines to two that had averaged about $700 a month.
When you need someone accountable for technology decisions — not a help desk — I act as your fractional CTO: vendor selection, build-vs-buy calls, AI readiness, and roadmaps. I’ve built and run this infrastructure as an operator, not resold someone else’s.
Fourteen years running the technology behind a 10-location, three-state retail operation — custom software, integrations, networks, cloud, and telecom — backed by two decades of independent IT consulting. The same person who does the work advises the strategy.
I've been building, fixing, and running business technology since 2005 — infrastructure, software, and telecom. Chances are I've already solved a version of your problem, so you get proven patterns, not experiments.
I reach for proven open-source and low-cost platforms first — pfSense instead of firewall licensing, self-hosted tools instead of per-seat SaaS — so your budget goes to outcomes, not subscriptions.
No contracts, no minimums — I work month-to-month. Scale me up for a big build, down for maintenance, or off entirely. I earn the next engagement by delivering this one.
Automation is the highest-ROI work I do — the 100,000+ hours I've saved clients came from killing repetitive manual tasks. If your team does it by hand every week, I can probably make it automatic.
Tell me the manual process, the systems that won’t talk to each other, or the technology decision you’re stuck on. You’ll deal with me directly — the person who’ll actually build it — not a sales rep. If it’s a fit, I’ll tell you; if it isn’t, I’ll tell you that too.
I design and build automation-driven systems that connect applications, infrastructure, and people. My work spans LAMP development, enterprise integrations, telecom platforms, and long-term modernization initiatives—focused on reliability, scalability, and practical impact.
A ground-up revamp of my own platform: 123 case studies elevated into one design system, 170 branded archives, and a one-page site with a scored intake and live Teams booking — built AI-assisted with Claude Code (Opus & Fable).
A PowerShell system enforcing granular Exchange Online email retention — enterprise-grade mail management in-house, without the premium Microsoft 365 license.
An in-house Mailgun alternative — PHP endpoints using Microsoft Graph to subscribe to a shared mailbox and maintain threaded email conversations, no third-party email service required.
Revamped AccuDash inspection questions to auto-generate the back-office claims paperwork — adapting to the loss of service labor credits.
Service tickets in AccuDash now update automatically from technician outcomes and build their own bills — more accurate billing with far less back-office work.
An open-source, federated governance platform that compiles a written constitution into running software — PR-STV elections with cryptographic ballot secrecy, courts, and a redistricting engine over ~951,000 real-world jurisdictions. Laravel, PostGIS, Vue, Matrix, Docker.
