Complex architectures, built on any stack.
We design, build and run complex software: booking engines over millions of hotels, a public blockchain network, health-data and AI research platforms. The stack follows the problem, never the other way round.

Why an SEO agency builds software
Technical SEO at scale is not a checklist. It is rendering pipelines, crawl budgets, page speed, structured data, site migrations and log analysis across millions of URLs. That is software engineering, done under the strictest reviewer there is: a search engine that re-tests your site every day.
The skills that make a large site rank are the skills that make a large system work.
So our engineering and our search work reinforce each other. Every platform we build is fast, crawlable and measurable from day one, and every search engagement is backed by people who can change the code, not just report on it.
What we build
From the first architecture sketch to years of support, with one accountable lead.
Architecture & solution design
System design, data models, integrations and security from the first workshop, documented so your team can own it.
Web platforms & portals
Customer-facing platforms and portals that are fast, accessible and search-ready by default.
Back-office & business systems
Internal tools, workflows, CRM and reporting that replace spreadsheets with software.
Data, analytics & AI
Pipelines, dashboards, machine learning and AI features embedded in your product and operations.
Distributed & high-load systems
Networks, nodes, bridges, explorers and RPC infrastructure built for uptime under load.
Integrations & automation
APIs, payment and supplier integrations, and the automation that connects your systems.
Simple, observable, built to be supported
We choose the simplest architecture that fully meets the requirement: open technology, few moving parts, backups and monitoring from day one. Fewer moving parts means fewer things to break and a lower cost to run.
Specialised across fields
Our engineering experience comes from building and running our own platforms in demanding sectors, alongside the search and digital work we have done for clients since 2009.
LockTrip
Our own online booking engine over about 2 million hotels from 15+ B2B suppliers, with web and mobile apps, ML and AI automation.
Hydra Chain
A public layer-1 network with node, bridge, block explorer and RPC infrastructure, designed and operated by our team since 2019 (live 2020); plus the HydraGon DEX and changeX apps.
bioArc
Our own genomics and health platform that cross-references DNA with blood biomarkers.
Quantune
Our own AI research platform for strategy optimisation and walk-forward backtesting.
Client work
SEO, content and paid search for clients in finance, travel and e-commerce, including an 86% rise in organic visits for Credissimo.
Client work
Websites and online stores designed, built and maintained for client brands, with search performance designed in.
LockTrip, Hydra Chain, bioArc and Quantune are our own products. More in our portfolio and client case studies.
