euphoricquartz.com — software & AI engineering
Quartz keeps
the time.
We build
what runs on it.
Quartz sits inside every machine that computes. Cut a crystal, apply a voltage, and it vibrates at a rate so stable that a processor can count on it — the oscillator is how a system perceives time at all.
That vibration is euphoric: a resonance held at exactly its own frequency. We write the software layer that sits on top of it — apps, integrations, and AI systems for businesses that need them to actually work.

01 / Services
Software and AI, built end to end
Apps, backends, integrations and AI systems — designed, built and delivered by the same engineer. Every project is quoted on its own: scope, price and delivery date agreed before it starts. For industrial companies there is a closed pack with published prices.
02
Backend, APIs and data
Data models, authentication, row-level security and scheduled processes, on infrastructure that stays cheap to keep running.
PYTHON · FASTAPI · POSTGRES
03
AI inside software that already exists
Assistants, semantic search and structured extraction added to a product already in production, without rewriting it.
LLMS · RAG · PGVECTOR · HYBRID SEARCH
04
Private AI, on-premise
Local models on your own infrastructure or on a private GPU server. No cost per use, and no data with third-party providers.
SLMS · QUANTIZATION · VLLM · PYTORCH
05
Automation and data acquisition
Scraping, scheduled pipelines, agents and automatic rundowns — the repetitive work running on a schedule instead of by hand.
AGENTS · SCRAPING · PIPELINES
06
Integration and compliance
The ERP and the tools you already run, connected; GDPR, DAC7 and identity verification handled as part of the build.
REST · WEBHOOKS · GDPR · KYC
02 / Team
The person you talk to is the person who writes the code
EuphoricQuartz is one engineer. There is no account manager between the brief and the build, no team to hand the project down to, and nobody learning on your budget.
