DXX // SYSTEMS
A specialist firm engineering digital systems end to end — secure infrastructure and payments; custom AI from prompt design through vision-language and multi-modal model training; perception, robotics, and aviation-grade operations surfaces; firmware-level repair and IoT vendor lockdown when sensitive estates have to operate clean. Built for operators whose systems must perform under scrutiny and remain defensible under audit. Every engagement is bespoke. Every artifact is built to be trusted. Established 2017 — over nine years of shipping production digital systems.
▌▌▌ 01 / CAPABILITIES ▐▐▐
Twenty-eight capabilities across nine disciplines, one conviction holding them together: build local-first, instrument every surface, and ship systems that hold up under audit, under load, and under adversarial pressure. From a same-week web build to a fine-tuned multi-modal model, from sealed-room firmware repair to courtroom-grade leak attribution — every engagement is bespoke, every artifact is defensible the day after delivery and the year after. Select any capability for the deeper write-up.
Production-grade websites, web apps, and interactive mockups in days, not quarters — from validation prototype to shipped product.
→ SVC-02Rust, Tauri, and native Win32 — desktop software with the durability of server code.
→ SVC-03Ledger, settlement, reconciliation, and PCI-aware payment flows engineered for resilience.
→ SVC-04Bespoke topology, transport, and data plane design — from QUIC relays to PostGIS clusters.
→ SVC-05Converting legacy databases into AI-friendly stores with enriched metadata, plus general database migration and management.
→ SVC-06Systematic prompt design, evaluation harnesses, and policy scaffolding for production LLM use.
→ SVC-07Purpose-built models end to end — including vision-language and full multi-modal custom training.
→ SVC-08Domain adaptation of open and frontier models — supervised, preference, and continual approaches.
→ SVC-09Purpose-built synthetic data — text, audio, video, documents, chat logs, structured records — for training custom AI.
→ SVC-10Commercial-use pipelines for stills, motion, and avatars — licensing-clean and brand-safe.
→ SVC-11Task-specific object, motion, depth, and situational-awareness tracking on image and video streams.
→ SVC-12Comprehensive digital twins — voice, appearance, mannerisms, and knowledge — that converse and respond as the original.
→ SVC-13Bespoke AI that spiders into every aspect of your personal and work life — a senior chief-of-staff that never sleeps.
→ SVC-14Purpose-built runtimes for agents, evaluations, and operator workflows — the substrate your AI runs on.
→ SVC-15Synthetic divisions and whole-company simulations — stress-test org design before a single hire is made.
→ SVC-16Bespoke simulators for any domain — finance, supply chains, networks, ecology, infrastructure — to track any metric in an artificial environment.
→ SVC-17Antivirus integration, prompt-injection defense, supply-chain attestation, runtime policy.
→ SVC-18Continuous telemetry, anomaly detection, and automated containment across distributed estates.
→ SVC-19Custom monitoring agents for NVR and camera fleets — discovery, extraction, alerting, lockdown.
→ SVC-20Bespoke cryptography for sensitive deployments — custom schemes, sealed channels, key management, and lawful decryption assistance.
→ SVC-21Per-recipient fingerprints, embedded telemetry, and canary tokens across docs, media, and code — leak attribution that holds up in court.
→ SVC-22CAN bus emulation, synthetic sensor streams (thermal, optical, audio, telemetry), and bench harnesses for robotics development.
→ SVC-23Pilot-assist surfaces, ATC and ground-control modules, airport-wide data integration, and operational monitoring.
→ SVC-24Real-time GPS tracking, asset management, dispatch and routing, and management portals for fleets and field operations.
→ SVC-25Unifying incompatible IoT devices into a single platform an AI can actually manage — protocol-neutral, local-first.
→ SVC-26Egress lockdown, firmware hardening, and local-only operating modes — your sensitive feeds stay where you put them.
→ SVC-27Sealed engineering environments for IP-clean rebuilds, sensitive reverse work, and high-trust deliverables.
→ SVC-28Recovery, repair, and exploration of corrupt or modified firmware. We work at the layer below the OS.
→▌▌▌ 02 / SELECTED DOSSIER ▐▐▐
Server-rendered marketplace with agent workspaces, brokerage management, public search, homeowner dashboards, and mortgage referral pipeline. Engineered for geographic-scale ingestion and field-team workflows.
Agentic operating layer with persistent memory, modular skills, voice integration, prompt-injection policies, and a continuous-learning loop. Deployed against a senior operator's daily workflow.
Full-duplex audio, bounded-latency inference, identity persistence, and commercial open licensing. Built without gated APIs so deployment is portable across customer infrastructure.
Rust + egui command center managing remote shell, file dedupe, encrypted vaults, camera/NVR lockdown, and self-hosted QUIC relay. Authorization-gated end to end.
WASAPI audio capture, VAD endpointing, low-latency local ASR with frontier fallback, exposed as a local HTTP service for desktop and shell integrations.
Role-based dashboards spanning dozens of ministries, hundreds of case records, and an ATC-style operations monitoring module for inter-agency coordination.
Document-grounded retrieval system with PDF ingestion, canvas-level rendering, and citation-traceable answers — every claim resolves back to the exact page that supports it.
Excel, calendar, mail, and public-fact merge consolidating into a clean relational store — with conversion metrics, offer tracking, and CRM seed tables ready for downstream import.
Virtual-employee task intake, role assignment, approvals, and escalations simulated against a discrete-event engine — used to model headcount strategy and operating cost before a single hire is made.
Cross-platform desktop chat surface with drag-and-drop composition, markdown, and on-device vision ML tasks — built in Tauri + React/TypeScript with native file system integration.
Bespoke vertical platform for vehicle data, ownership, and service workflow — a Rust workspace engineered for the data-quality realities of the automotive domain.
▌▌▌ 03 / APPROACH ▐▐▐
Three principles drive every engagement. They sound simple. They constrain every architectural choice we make.
We design systems that own their data, run without vendor-locked APIs, and degrade gracefully when the network does not cooperate. The cloud is an option, not a requirement.
Authorization gates, audit-first logging, prompt-injection policies, encrypted vaults, and supply-chain attestation are baselines — not features added after a breach.
We ship Rust on the server, Rust on the desktop, and treat Windows as a first-class deployment target. Bounded latency, structured concurrency, and observable systems by construction.
▌▌▌ 04 / CONTACT ▐▐▐
Tell us what you're trying to build. We respond within one business day with a scoped proposal and, when appropriate, a live walkthrough of a comparable engagement under NDA.
We do not share inbound communications with third parties. NDA on request.
Adult, mature, and age-restricted commercial engagements are accepted on the same terms as any other engagement: proprietary, audit-defensible, and discreet. We do not moralize legitimate commercial work.
