LUDDAN SERVICES LLC — Florida sole-owner LLC. We build AI-augmented workflows for companies under 50 people, and 3D-printed tooling for the Homestead spaceport ecosystem. Pre-revenue, available for pilot engagements. Pricing: small monthly retainer + 10% of measured savings.
We build home software that works without the cloud — your cameras, devices, and family data stay in your home, not on someone else's server. Our product Nexum is used daily by real families.
A growing portfolio of residential properties managed with the same discipline and long-term thinking we apply to software — value-driven, quietly held, and built to appreciate.
A pipeline of research-driven ideas across AI, identity protection, financial intelligence, and beyond. We invest time before we invest capital — ideas earn their way in here.
One app that controls your whole home — cameras, thermostat, smart devices, and more. Everything runs inside your house. No monthly fees, no outside company involved.
Control your lights, cameras, thermostat, and more from a single screen — no switching between 5 different apps.
Pay once, own it forever. Nothing is sent to the cloud. Your home's information stays in your home.
Every person gets their own login and their own view. Set it up once — everyone uses it their way.
We invest in residential real estate with patience — no flipping, no rushing. Properties that generate value year after year, in markets we understand.
Investment property in Indian River County. A long-term hold focused on appreciation and value in a growing Florida coastal market.
Primary family residence in Miami-Dade County, Florida. Home base and operations center, fully managed by Nexum's home intelligence platform.
Ideas that start as research and earn their way into products. We move carefully — every project here is backed by real data before a single line of code is written.
A growing system of specialized AI agents for research, finance, security, marketing, and daily intelligence briefings.
Proactive monitoring of credit changes, property deed transfers, dark web mentions, and stolen identity signals — before they become problems.
AI-powered tax expertise, portfolio analysis, and financial monitoring integrated directly into the Nexum platform.
Network hardening, threat detection, and security auditing — built on authoritative research and applied to real home networks.
Nexum in English, Spanish, Mandarin, French, and Portuguese — making home intelligence accessible across languages and households.
Research into new verticals and markets. LUDDAN SERVICES is designed to expand — each division a foundation, not a ceiling.
The Mac-native control surface for every device in the home. Alexa, Ring, Honeywell, Bambu, vacuum robots — vendors that ship mobile-only apps, unified into one Mac interface.
Multi-printer fleet controller — vendor-agnostic adapters, materials AI, virtual stress testing, secure model import gate, autonomous print queue. Self-hosted on customer hardware, no cloud dependency.
Every 3D print runs through finite-element stress analysis before any filament melts. Material recommendations for the use case (load, climate, finish). No materials-engineering background required.
A printed reference frame plus an AI vision pipeline turns any phone photo into a real-world 3D measurement. Scan an object, model it, print a copy — all from a single picture.
Standing LAN observatory: device inventory, security posture, anomaly detection, usage-pattern learning. The data feeds future automations and stays entirely on the home network — never uploaded.
An autonomous research role that maintains a per-device reference library, monitors firmware advisories, scrapes community forums for troubleshooting, and surfaces issues before they break things.
Project names shown reflect ongoing research and development; concept descriptions are forward-looking and represent current development direction. References to third-party hardware, software, or vendor names are made for informational and interoperability purposes only and do not imply affiliation, endorsement, or partnership.
A running log of everything that went out the door — calibration tools, printable parts, agent improvements, reliability fixes. Measured from day one.
Hours from session transcripts; active coding only, idle time excluded. Counts from session logs and working tree as of 2026-06-12.
Letter-size printable reference: four ArUco corner markers, a full Charuco board, twelve color swatches, sub-millimeter tick rules, Siemens stars, line-width gauges, and an embedded QR with metadata.
Reads HEIC/JPG/PNG natively, detects all four ArUco corners, derives pixel-per-mm scale, and emits a perspective-corrected top-down view. Any phone photo becomes a measurable image. No manual calibration.
Every printed part now carries an engraved company wordmark, project ID, material, date, and a scannable QR. Implementation rasterises the brand to a 2D mask, fuses contours into a single watertight prism, and engraves cleanly without inflating mesh volume.
Redesigned in-house printer accessory: 136 g → 55 g, 370 min → 148 min print time, watertight, branded. Achieved through tighter outer dimensions, 1.6 mm walls, and replacing a solid wedge with a thin tilted floor.
Direct MQTT-TLS subscription to the printer on port 8883. Sub-second state capture, debounced transition alerts, no SSH polling. Operates as a persistent system service and never silently loses a session.
When an upstream dependency is unreachable, the poller now backs off to hourly probes, fires exactly one actionable alert, and auto-resumes when the dependency recovers. No alert spam under known-bad upstream conditions.
Auto-builds a single-page status report — done, in flight, pending, print queue, inbound — pulled from session memory and project state, delivered as a document on demand.
A typed memory store (user, feedback, project, reference) survives across sessions and is indexed in a single manifest. Hardware quirks, prior incidents, working preferences, and ongoing project state all carry forward.
Eleven live integrations across 3D printer, thermostat, paper printers, network gear, droplet host, compute fleet, phone and tablet. Documented end-to-end so nothing slips. Browse the matrix →
Two scheduled agents on the home backend: 08:00 nmap inventory diff (alert on new MACs, vanished hosts, IP changes), 09:00 top-100 port scan with always-on flags for cleartext / risky services.
Pulls the public Have-I-Been-Pwned catalog daily, diffs growth, flags any new breach touching watched company domains.
Scan an object on iPad Pro with Polycam, AirDrop the mesh to the iMac. A watcher cleans normals, decimates to ≤80k faces, applies the brand engraving, auto-assigns the next P-### print ID, renders a thumbnail.
Daily scrape of community-source RSS filtered for P2S-relevant keywords — HMS codes, firmware advisories, recall language. Critical hits raise immediate alerts; everything else accrues to the hardware reference log.
Five-second analytical screen for printed parts: cantilever / compression / shear modes against PLA, PETG, ABS, PA, PA-CF and TPU yield strengths. Ran over the current print queue and found optimization opportunities.
Project memory indexed by a local Ollama embed model (nomic-embed-text, 768d). Daemon questions check the local index first; only fall through to the cloud API when no high-confidence match exists. Cuts API tokens 3-5×.
Every active design auto-rendered with thumbnail, mass, dimensions, and watertightness status. Browse the catalog →
Parallel health checks across iMac, reComputer, OptiPlex, and RPi every 60 seconds. Auto-routes every AI request to the fastest available node, fails back in under two seconds, and surfaces cluster state on a live Nexum dashboard.
Live debt tracker seeded with eight active accounts. Hybrid avalanche/snowball paydown engine runs daily and surfaces the optimal next payment. All figures pulled directly from the household ledger — no spreadsheet required.
Customer and contact management for fleet operations. Eleven REST routes covering account creation, contact roster, and job history. Full dark-theme SPA wired into the FleetIQ sidebar alongside PM tracking and inspections.
Vendor invoice intake, payment tracking, and import-from-AP workflow. Fourteen routes. Bill aging, payment history, and budget-vs-actual reconciliation across job cost codes.
Cost-code level job tracking tied to AP bills and time entries. Budget vs actual reporting per job, import path from AP module, and migration that retrofits job numbers onto existing bill records.
Incident reporting with auto-case-numbering (INC-YYYY-NNN), witness tracking, root-cause closure, and OSHA 300 recordkeeping per 29 CFR 1904. KPI strip shows TRIR, DART, and days since last incident.
Swept all 75 routers for unprotected endpoints, fixed six auth bypasses, added INGEST_TOKEN service-to-service auth, eliminated 401/403 log spam, and drove the backend error rate from 75 errors per day to zero.
Single CSS token file controls color, typography, and spacing across all three platforms — Nexum (30+ pages), FleetIQ, and luddansvcs.com. Deep space dark background, teal accent, Inter font. One variable change updates everything.
We don't take outside investment. We don't answer to boards. That independence lets us make decisions based on what's right for the long term — not the next quarter.
When we can build it, we do. The Nexum platform exists because existing tools didn't meet the bar. We use all our resources before reaching for something new.
Every product starts as a research project. Our AI crew investigates ideas, surfaces risks, and builds confidence before we commit engineering time.
Whether it's a property held for decades or software architected to last — we optimize for durability, not headlines. Slow, steady, compounding growth.
