The Alternative
Why Citus?
We're not a faceless agency. We're your dedicated engineering task force.
vs. Big Agencies
✗ £300+/hr, you talk to account managers, not engineers. Budget overruns are the norm.
✓ Direct engineers from day one. One flat fee agreed upfront — never billed for a surprise.
vs. Freelancers
✗ One dev can't cover mobile, backend, AI, and DevOps. You end up managing four people.
✓ Full-stack team, one contract. We cover the whole stack so you never have to juggle.
vs. Offshore Agencies
✗ Timezone chaos, language barriers, and throwaway code you'll rewrite in a year.
✓ UK-based, English-first. We treat your product like our own — our reputation depends on it.
[ ZERO LOCK-IN ]

[ SHIPPED CODE ]
FlexiDiet
Third-generation AI nutrition tracking — a shipped, monetised iOS & Android app.
Business Outcome
Enabled seamless monetization via Apple/Google subscriptions with zero manual human support required.
FlexiDiet replaces tedious manual calorie counting with conversational AI and camera-based food recognition. It features a breakthrough "AI Progress Meeting" — a fully automated, weekly 5–10 minute audio podcast generated entirely from your personal nutrition data, where two AI agents debate your wins, challenges, and goals.
Tech Stack Specs
›Built with Flutter for iOS/Android, backed by Firebase and Python Cloud Functions.
›LangChain and Google Gemini Flash for function-calling workflows.
›Gemini Vision for instant multi-item nutritional breakdowns from photos.
›Intelligent 7-day meal planner using vector search Retrieval-Augmented Generation.
UniBreeze
Secure, verified peer-to-peer campus marketplace for the University of Glasgow.
Business Outcome
Bypassed the cold-start problem by automating supply-side moderation and verification with OpenRouter.
UniBreeze is a modern classified ads platform built exclusively for students. It ensures a safe trading environment for textbooks, electronics, and furniture by requiring strict @student.gla.ac.uk email verification and utilizing an automated Discord bot for role management.
Tech Stack Specs
›TanStack Start web platform + React Native (Expo) and Flutter mobile clients.
›AI moderation via Grok-4 (via OpenRouter) screens images for explicit or non-product content.
›Real-time Cloud Firestore subscriptions for instant direct messaging and offers.
›Embedded AI support chatbot with context-aware tool calling and Stripe Connect integration.
VoxGuard
Sub-200ms voice intent classification pipeline for live AI voice systems.
Business Outcome
Delivered a massive UX upgrade by allowing fluid, natural human-AI conversation without lag.
When an AI assistant is speaking and a user makes a sound, current systems either ignore it or interrupt completely. VoxGuard solves this by differentiating conversational "backchannels" (e.g., "uh-huh", "right") from genuine interruptions in under 200 milliseconds.
Tech Stack Specs
›4-tier pipeline: Rule-based (10 languages), Timing, Acoustic Energy, and Gemini 2.5 Flash Lite fallback.
›Processes raw PCM audio locally to track energy slopes and zero-crossing rates.
›Learns individual user speech patterns to dynamically adjust confidence thresholds.
›Native adapters for Gemini Live, OpenAI Realtime, and streaming ASRs (Deepgram, Whisper).
CarPulse
AI-powered OBD-II vehicle diagnostics and automated mechanic data generation toolkit.
Business Outcome
Slashed diagnostic mechanic costs via an automated LLM data-generation pipeline.
CarPulse is a Flutter-based OBD-II diagnostic app for iOS and Android that translates complex fault codes into plain English. Under the hood, it is powered by an advanced, AI-driven data generation pipeline that maps comprehensive vehicle databases and manufacturer-specific Diagnostic Trouble Codes (DTCs).
Tech Stack Specs
›Python-based AI toolkit utilizing OpenRouter API and live web scraping to systematically build code libraries.
›Global coverage configuration across US, EU, UK, and Asian markets (Hybrid and EV specific).
›Local encryption scripts safely package generated JSON/CSV libraries before shipping to the Flutter bundle.
›Implements rigorous automated cost tracking and caching for LLM API usage.
