Web & product engineering at Elvnn is end-to-end development for founders, operators, and brands. We build marketing sites that load in under a second, product cores with multi-tenant auth and real-time surfaces, and reusable design systems that outlast individual projects. Every engagement is TypeScript-first, uses modern web components where they earn their place, and is instrumented for performance from day one. We stay hands-on the whole way: the same engineers who write the interface components also configure the CI, the CDN, the analytics, and the observability. Launches ship with Lighthouse mobile ≥ 90, LCP under 2.5s, and a preview URL your team has been watching for weeks, not days.

Common questions about web & product engineering
Which stack do you default to?
A modern TypeScript-first web stack with Tailwind for styling. For data: Postgres with typed ORMs. For auth: hosted providers such as Clerk or Supabase. For payments: Stripe. We adapt when a project calls for it, but these are where we are fastest.
Do you work with legacy codebases?
Yes, especially for product teams rebuilding a v2. We start with a short audit, ship a new marketing site or landing first, then migrate core surfaces in parallel with feature work.
How do you handle production monitoring?
Sentry for errors, hosted web vitals + speed insights, and PostHog or similar for product analytics. Everything is wired before launch, not after.
