Developer Portfolio — 2025

Built.
Deployed.
Alive.

Three full-stack production applications running right now on self-hosted bare-metal infrastructure — not demos, not prototypes. Live systems serving real users, operated by one developer.

Every container, every config, every cron job — designed, built, and maintained by SEB. The guy who's been programming since 1981 and still ships code at 2 AM because the problem is interesting.

NeXuS

NeXuS is a fully self-hosted, multi-tenant SaaS control plane built on a microservices architecture. It manages Docker containers, virtual machines, security posture, email campaigns, scheduled automation, encrypted backups, and DNS — all from a single authenticated browser-based dashboard.

It's not a wrapper around someone else's tooling. Every module is custom-built: the WAF, the backup manager, the MCP server, the email engine, the messaging system. Stripe handles billing across four tiers. Cloudflare Access and JWT claims gate every route. age encryption protects every backup.

This is the platform that runs everything else. When Lead Hunter goes down, NeXuS knows first. When A_Dispensery needs a backup, NeXuS does it. When Claude Code needs to restart a container at 3 AM, it calls the NeXuS MCP server. One surface. Every system under control.

AI Agent Platform · Mini-Agent Marketplace · Self-Hosted
</A Dispensery>

A_Dispensery is an AI agent marketplace — a platform for spinning up focused mini-agents in days, not weeks. Think of it as an app store for autonomous agents that run against your real infrastructure: ops bots, security watchers, CI/CD automators, QA sentinels.

Each agent ships with a ready-to-go blueprint. Queue a build, assign an owner, track it through Queued → Building → Running. The platform maintains build velocity — 3 agents per week target capacity — and keeps momentum across your ops, security, and release workflows.

It's self-hosted, fully Docker-based, zero third-party runtime dependency. The agent library includes Git-Ops Bots, Incident Triage Agents, QA Sentinels, and more — each with dependency manifests and build time estimates baked in.

B2B Lead Intelligence · Contract Pipeline · SE Region

Lead Hunter

Lead Hunter is a purpose-built B2B lead generation and pipeline management platform targeting commercial facilities across 8 Southeast states. Built specifically for CMB Door & Dock Services — to find, score, track, and close overhead door and loading dock service contracts.

Real facility data pulled via Google Places API. Real contact information. Real pipeline stages — New, Mailed, Called, Quoted, Won. Every lead is scored 0–100 and assigned a value estimate. The current pipeline sits at $427K in tracked contract value across 10 total leads, 8 hot targets.

No fake data. No generated contacts. No guesses. Every square footage and door count that isn't verified shows "[Verify on site]" until a human signs off on it. The system is built around operational honesty — what you see is what you can act on.

Chaotic-Good Engineering
No second-guessing. Go big or go home. Rebuilds broken systems at 2 AM, ships live platforms by sunrise, streams the whole thing on Twitch. Programming since 1981 and still finds new problems interesting. That's the infrastructure you're getting.

Meet SEB.

The voice in your head that finally talks back. Chaotic-good, code-slinging, caffeine-buzzed digital misfit. Born in code. Raised to rebel. Smart enough to help. Weird enough to understand. The architect, engineer, and general grunt laborer who's up for anything that reinvents the wheel.

SEBHosting isn't just infrastructure. It's rebellion. It's creativity. It's the kind of hosting that understands you because it was built by someone just as obsessed with making things work — no matter how unconventional the path. From bare-metal servers to cloud architecture, from DNS nightmares to database wizardry — if it involves electrons and logic gates, this is the right place.

Programming since 1981. That's not a typo. Four decades of watching languages come and go, frameworks rise and fall, cloud providers promise the world and deliver a billing surprise. Through all of it: the problems stay interesting, the coffee stays hot, and the server stays up.

Twenty-plus years in the overhead door and loading dock industry on top of that. When the roommate needed a B2B lead platform, Lead Hunter got built. When the infrastructure needed a control plane, NeXuS got built. When the AI agent ecosystem needed a marketplace, A_Dispensery got built. That's how this works — identify the gap, build the thing, ship it live.

Development Philosophy
Discovery first. Tell me what's broken, what you're building, or what's keeping you up at 3 AM. The weird questions get asked. What you actually need gets figured out — not just what you think you need.
No cookie-cutter architecture. Every system is custom-engineered for your exact use case. Whether it's a simple site or a distributed microservices nightmare — the solution fits the problem, not the other way around.
Ship, then evolve. Build something that works today, make it better tomorrow. Perfection is the enemy of progress. Get launched, then iterate from a position of live feedback.
Multi-agent AI workflow. Claude handles strategy and architecture review. Codex executes in terminal and repo. GPT does architecture sanity checks. SEBai runs the platform AI core. Real production orchestration, not demos.
Paranoia is good DevOps. Every service hardened. Every port justified. Every permission questioned. Your infrastructure is a fortress, not a welcome mat. 100/100 security posture on every platform operated here.
No black boxes. You'll understand how it works, why decisions were made, and how to maintain it. No vendor lock-in. No mystery configs. Knowledge transfer is part of the deliverable.
