Expertise
We keep a deliberately narrow toolset and go deep on it. Fewer technologies means fewer unknowns, faster delivery, and a codebase your own team can pick up.
Language
One language across the browser, the server and the build scripts, with types shared rather than duplicated. Most integration bugs become compile errors instead of production incidents.
Web framework
Server rendering by default, so pages are fast on a mid-range phone and legible to search engines. Caching is explicit and per-route rather than something you hope a CDN gets right.
Data
Relational, transactional, and boring in the way infrastructure should be. Constraints live in the database, so a bug in one service can't quietly corrupt everyone else's data.
Mobile
One codebase and one team for iOS and Android, sharing business logic with the web app. Over-the-air updates mean a fix ships in hours, not in a store review cycle.
Interface
A constrained set of colour, spacing and type values rather than ad-hoc styling. Design stays consistent as a codebase grows and as new people join it.
Infrastructure
Vercel, Supabase and similar managed services in place of servers we'd have to patch. Every deploy comes from a commit, so any release can be identified and rolled back.
Engineering standards
The parts of the work that don't appear in a feature list, and that cost the most to add afterwards.
