Static memory, fixed schedules, no hidden allocation on a control path. If the timing cannot be reasoned about, it does not ship.
Engineering systems & R&D
Machines that have to be right.
Five systems: a post-quantum WAN mesh, a deterministic building-code solver, an SMT contract risk engine, a thermodynamic virtual battery, and a volumetric 3D printer. Independent research where the timing has to be provable and the maths has to hold.

Vantablack
Every message leaves by three roads at once, and no machine on any of them holds the whole thing.
The problem
A VPN provider sees every site you visit, keeps logs, and can be ordered to hand them over. Separately, traffic recorded today can be decrypted later if quantum computers get strong enough.
How it works
Vantablack connects your machine to other machines and uses them to carry your traffic. Each message is encrypted with hybrid ML-KEM-768 and X25519, split into three Reed–Solomon shards, and sent along divergent routes. A shard that arrives modified fails its own authentication tag and is discarded before reassembly.
What it gives you
- No provider. There is nobody holding your traffic to log it.
- Post-quantum encryption. ML-KEM-768 with X25519, so a recording made today has to be broken against a cipher built for later.
- Tamper detection. Every shard carries its own HKDF-derived key and Poly1305 tag.
- Packet-loss tolerance. Any two of the three shards rebuild the message.
Setup
cargoLimits
Running it means running a node. There is no support and no company responsible for your uptime. The seven-node Level 2 carrier mesh is a simulation, and the physical-anchor modules ship disabled by default.

BauLens
Deterministic German and EU building code compliance validation engine, checking architectural parameters before ground is broken.
The problem
Building regulations in Germany (BauGB, LBO) and European standards are intricate, distributed across state-specific ordinances, and traditionally validated through manual expert reviews. Errors caught late incur severe project delays and permit rejections.
How it works
BauLens parses IFC/BIM structural models and dimensional specs into an abstract regulatory syntax tree. Rule engines run deterministic geometric, fire safety, escape route width, and accessibility clearance checks against DIN and Eurocode criteria without cloud dependencies or black-box heuristics.
What it gives you
- Zero-hallucination compliance. Pure deterministic rule execution against authoritative state building ordinances.
- IFC & BIM integration. Direct spatial parsing of architectural geometry, egress corridors, and stair pitch tolerances.
- Instant permit pre-check. Generates audit-ready compliance dossiers with exact legal citations.
- Local air-gapped runtime. All calculation happens on-device with zero exposure of confidential architectural blueprints.
Setup
.ifc architectural model or dimensional JSONLimits
Validates geometric, structural, and dimensional criteria; legal interpretations of discretionary zoning clauses still require licensed surveyor sign-off.
Figures
ClauseLens
Automated contract clause contradiction and risk scoring engine grounded in formal logic.
The problem
Commercial agreements hide conflicting indemnities, ambiguous termination rights, and contradictory governing law clauses across hundreds of pages of schedules and amendments.
How it works
ClauseLens translates contractual commitments into deontic logic specifications (obligations, permissions, prohibitions). It then evaluates mutual consistency and liability caps across interdependent documents, surfacing direct logical contradictions and unmitigated exposure.
What it gives you
- Automated contradiction detection. Identifies conflicting covenants, overlapping notice windows, and mutual exclusivity paradoxes.
- Bounded risk scoring. Quantifies structural exposure across indemnity caps, force majeure, and dispute escalation trees.
- Deontic logic graph. Visualizes dependency chains between conditioned obligations and payment milestones.
- Client-side execution. Complete confidentiality — documents are analyzed locally in-memory without third-party LLM transmission.
Setup
Limits
Evaluates logical contradictions and parameter boundaries; jurisdiction-specific common law case law nuances require human legal counsel.
Figures
Ambient Thermal Arbitrage
Virtual battery energy management system that turns building thermal mass into high-efficiency distributed grid storage.
The problem
Electrochemical batteries (lithium-ion) carry heavy capital costs, degradation cycles, and supply chain constraints. Meanwhile, existing heat pumps and HVAC systems consume energy reactively rather than leveraging dynamic day/night thermal capacitance.
How it works
Ambient Thermal Arbitrage calculates high-resolution thermodynamic drift models for physical building structures. By predicting ambient weather gradients and dynamic electricity spot prices, it pre-cools or pre-heats structural thermal mass within tight comfort deadbands, arbitraging power prices without electrochemical wear.
What it gives you
- Zero chemical degradation. Exploits physical structural mass as a maintenance-free virtual storage battery.
- Spot-market price arbitrage. Shifts megawatt-scale demand curves to negative or lowest-cost tariff windows.
- Rigorous comfort envelopes. Guaranteed interior temperature adherence using bounded predictive control.
- Rust embedded runtime. Low-power determinism suitable for direct edge deployment on building automation controllers.
Setup
cargo test — verify thermodynamic solverLimits
Effective thermal storage capacity depends on structural insulation and thermal mass; dynamic spot pricing requires smart metering infrastructure.

HoloForge
It prints the whole object at once, in the time a normal printer spends on its first hundred layers.
The problem
Layer-by-layer resin printers run for hours, leave stair-stepping striations where one layer meets the next, and print supports that have to be cut off afterwards.
How it works
HoloForge computes holograms that make 405 nm light from several rotary angles intersect only where the part should cure, then models what follows: radical polymerisation, dissolved-oxygen inhibition, and the surface the finished part measures.
What it gives you
- Under fifteen seconds per part, with no support structures to remove.
- Cure accuracy of 94.6–96.7% IoU in simulation, with under 0.02% overcure.
- Parametric generators for dental crowns, microfluidic chips and aspheric lenses, plus arbitrary .stl voxelisation.
- A vat aberration conjugate mask that cancels cylindrical vial astigmatism on the SLM, without an index-matching bath.
Setup
py -m pip install -e ..stl and synthesise the hologramsLimits
A simulated print is not a physical print. The optical and photochemical models are physical; the machine is emulated, and real output depends on your laser, your resin and your vat.

How the work gets made
Formal methods, SMT solvers, symbolic execution and reproducible builds. A claim without a check is a marketing line.
The kernel, the protocol layers and the domain surface are held to one engineering standard.
Selected systems are made open source or source-available to encourage independent verification and community improvements, alongside dedicated live runtimes.
Personal Lab & Background
About Keller Systems
I’m an IT Systems Integration Specialist (Fachinformatiker für Systemintegration) working in the industrial manufacturing sector in Germany. Keller Systems is my independent lab and personal hobby project — a place to build and refine systems that I aim to commercialize once ready.
Everything here was built out of genuine curiosity for how complex systems work under the hood — from post-quantum mesh routing and SMT logic engines to embedded kernels and physical computing. No bloat or unnecessary cloud layers, just self-contained code in Rust, Python, and TypeScript built for the fun of solving hard engineering problems.
Direct Engagement & Inquiries
Work with Keller Systems.
Independent systems research meets enterprise reliability. Whether you are looking to test a commercial engine, consult on deterministic industrial architectures, or review research specifications — direct founder communication, no ticketing queue.
