Type a query. Watch what it costs.
Most AI products die after launch — too slow, too expensive, too unstable. This is the routing we built so one didn’t. Every query is classified before any paid inference runs, so most traffic never reaches a model.

Claude Haiku parses intent to JSON, then OpenAI embeddings and pgvector cosine similarity in Postgres. Roughly 20% of traffic, under 1200ms.

Always-first AI follow-up for agents: Claude qualifies and routes every new lead—buyer or seller—while GPT-4.1 replies instantly on email and SMS and books showings 24/7, with every message tracked.
Multi-tenant microservice · Tiered search · Observable by design
Intelligent restaurant search
Conversational discovery with explicit routing, predictable AI unit economics, and latency targets suitable for high-volume production traffic.
How a project actually runs.
Discovery and plan
We agree on users, success metrics, constraints and risks, then produce a technical approach and milestone plan so everyone knows what “done” means and when.
Build in iterations
Working software every cycle, with demos, an open backlog, and early integration of auth, data and deployments — so problems surface when they are cheap to fix.
Launch and operate
Release with monitoring, runbooks and a sensible cutover. We support stabilisation after go-live and hand the system over properly.

Most engagements start with the two-week pilot below. We’ll give you a full quote for the wider build at the end of it, once we’ve seen the real codebase.
Two-week sprints, a demo at the end of each, a named escalation contact, and a written weekly report. Ask for a sample report and we’ll send a real one.
What we deliver
Services
Practical engineering aligned to your roadmap: you get transparent communication, measurable milestones, and software ready for real users—not a black box.
TypeScript & ReactNext.js & NodeMobile (iOS / Android)AWS & cloud-nativeAPI designAutomated testing
Custom product development
End-to-end web and mobile builds: discovery workshops, technical design, implementation, and handoff documentation—so your team owns the system with confidence after launch.
Platforms & integrations
Connect products to payments, CRMs, data pipelines, and internal tools with APIs and event-driven workflows that are observable, secure, and easy to extend.
Reliability & scale
Hardening for real traffic: performance tuning, monitoring and alerts, CI/CD, and operational runbooks—reducing downtime and making releases boring in the best way.
UX & frontend craft
Interfaces that match your brand and usability goals: accessible components, responsive layouts, and design-system thinking so new features stay consistent.
