Technical consulting · Since 2018

We build production software for small teams that need to ship.

Estalio Consulting is a technical consulting firm. We design, build, and operate web and mobile applications end-to-end — for founders, indie teams, and companies that treat engineering as a craft, not a checkbox.

// apps/native/src/app/index.tsx

import { supabase } from '@/lib/supabase'

import { Linking } from 'expo-router'

async function handleLink(url: string) {

const fragment = url.split('#')[1]

const p = Object.fromEntries(new URLSearchParams(fragment))

await supabase.auth.setSession({

access_token: p.access_token,

refresh_token: p.refresh_token,

})

}

// → session lands inside the Expo app

How we choose

Modern, conservative where it counts.

Frontend

TypeScript, React, Next.js (App Router), Expo for native and web, Tailwind, Radix.

Backend

Node and Bun, Postgres, Supabase, edge runtimes, Stripe, Anthropic and OpenAI APIs.

Infra

Vercel, EAS, GitHub Actions, fly.io and Render when servers are needed. Observability via OpenTelemetry and Sentry.

Practices

Typed end-to-end. Tests where they pay back. Small PRs. Honest estimates. No frameworks-of-the-month.

What we do

Six things, done well.

All services

Web applications

Production-grade Next.js, React, and TypeScript applications. Postgres, Supabase, Stripe. Auth, payments, edge deploys.

Mobile applications

Expo and React Native for iOS and Android. EAS Build and Submit pipelines. One codebase, two stores, plus a web target.

AI integration

Claude and OpenAI APIs in real products. Streaming, tool use, prompt caching, MCP servers. Past the demo, into production.

API & infrastructure

Node and edge runtimes, Postgres, queues, webhooks, observability. The unglamorous parts that decide whether the product ships.

Code review & technical audit

Independent reviews for founders evaluating a new codebase, an acquisition, or a stuck team. Plain reports, no theatre.

Technical advising

Build-vs-buy, stack selection, MVP scoping. Short engagements where a second perspective costs less than a wrong turn.

How we work

Small engagements, real ownership.

We take on a small number of projects each year — typically four to six concurrent engagements. The cadence is deliberate. We’d rather do good work on fewer projects than mediocre work on many.

Engagements start with a paid scoping conversation: a week to read the code, talk to your team, and write back with what we’d actually do, what it would cost, and what we’d push back on. If the fit isn’t there, the scoping note is yours to keep.

We work remotely, default to async, and ship in small increments. We use the tools you use. Contracts are short and plain-English. We invoice monthly.

Have a project that’s harder than it should be?

Tell us where you are and what’s stuck. We’ll reply within two business days with either a scoping plan or a referral to someone better suited.
