Custom Web Applications
SaaS dashboards, portals, kiosks — multi-tenant and role-aware.
The product-engineering bread-and-butter. Admin consoles, member portals, kiosk surfaces, multi-tenant systems with row-level security and audit-grade discipline.
What you get
4 pillarsMulti-tenant + RBAC
Row-level security, tenant isolation, role-aware UI. One platform, many customers, no leakage.
Real-time features
Presence, streams, collaborative editing — websockets and edge runtimes, not 5-second polling.
Kiosk surfaces
Glance-and-go iPad / tablet surfaces for guard shacks, fuel docks, check-in counters. Latency budget measured in milliseconds.
Admin tooling
The operator UI is treated as a first-class product, not an afterthought screen made of HTML tables.

Frequently asked
5 questionsWhat counts as a custom web application?
Anything beyond a marketing site: SaaS dashboards, internal tools, member portals, kiosks, marketplaces, operator consoles. If a user logs in, runs workflows, or sees data tailored to them, it's a custom app.
Do you build SaaS dashboards and member portals?
Yes — that's the most common engagement. Auth, role-based dashboards, billing, audit logging, and the admin surface to run it. Operator UI is treated as first-class, not a screen of HTML tables.
Multi-tenant support out of the box?
Yes. Per-tenant data isolation, per-tenant theming, plan-based feature flags, and admin tooling for tenant onboarding. Built on Postgres Row Level Security so tenancy is enforced at the database, not just the app.
What stack do you reach for?
Next.js 16 App Router + TypeScript on the front. Postgres (Supabase) or Convex for data and auth. Redis for queues and rate limits. Vercel or AWS for hosting depending on workload. Stack picked to fit the problem, not the other way around.
Typical build timeline?
A scoped v1 with auth, two or three core workflows, and an admin surface ships in 8–12 weeks. Heavier platforms with billing, multi-tenancy, and integrations run 3–5 months for v1.
