Marketplace, APIs and data flows
We design product, category, parameter, stock and order synchronization where a ready-made connector is not enough.
Marketplace product synchronizationLondon / senior software engineering
Software engineering London for business software that has to keep working after launch.
Thinqcraft helps London companies design, build and modernize full-stack business software: web applications, admin panels, marketplace integrations, data flows, Rails applications, PostgreSQL, CMS platforms and operational tools.
Remote-first market
London as a B2B market, with specialist delivery scope.
Searches like software engineering London or software development company London often lead to broad agency offers. We describe a clearer fit: full-stack business software, admin tools, integrations, backend architecture, modernization and maintainable operational workflows.
Scope
Dedicated full-stack software for business work that needs focus.
Rails, PostgreSQL and production rescue
We help stabilize existing systems: Rails upgrades, frontend migrations, queues, NGINX, Puma, Linux and PostgreSQL tuning.
Modernization and rescue workCMS, structured content and AI workflows
We build multilingual CMS platforms, knowledge systems, JSON-LD, Pagefind and controlled AI-assisted publishing workflows.
CMS and knowledge systemsProof
We work where software touches people, data, integrations and production.
For London searches, the important distinction is focus. We point away from broad agency promises and toward inspectable proof around full-stack business software, integrations and modernization.
- large product catalogs, marketplace feeds and reconciliation
- Rails 8, React 18/Vite, SolidQueue and Action Cable

FAQ
Common questions before the first technical conversation.
Does Thinqcraft have a London office?
We do not present a London office address. London is a B2B market for remote-first senior engineering work.
What London companies are a good fit?
London teams that need specialist remote-first engineering around web applications, admin panels, complex data, marketplace operations, Rails applications, CMS platforms, knowledge systems or production rescue.
What makes Thinqcraft different from a broad software agency?
Thinqcraft is a senior full-stack engineering team for systems where user workflows, backend architecture, integrations, maintainability and production responsibility matter.
Can you help with an existing system?
Yes. Much of the work is modernization, rescue, risk analysis, Rails and React/Vite migrations, PostgreSQL performance and production infrastructure cleanup.
