Custom App Development

AI-accelerated full-stack development. We build production-grade web and mobile apps in weeks, not months — with AI agents that help iterate designs, code, and deployments.

Key Capabilities

AI-Accelerated Development

Our coding agents handle boilerplate, testing, and refactoring — so our engineers focus on architecture and business logic. Ship in weeks, not months.

Designer Agent via Slack

Request design iterations directly in Slack. Our designer agent generates mockups, refines layouts, and exports production-ready components — no Figma back-and-forth.

Full-Stack Expertise

React, Next.js, Astro, FastAPI, Django — we pick the right tool for the job. Native iOS with SwiftUI, cross-platform with React Native.

API-First Architecture

RESTful and GraphQL APIs designed for scale, with auto-generated docs, versioning, and comprehensive test coverage from day one.

Cloud-Native by Default

Every app ships with Docker containers, CI/CD pipelines, Terraform infrastructure, and PR preview environments. Production-ready from commit one.

Rapid Iteration Loops

PR previews on every push. Weekly demos. AI agents that run tests, lint code, and catch regressions before you even review — so feedback cycles shrink to hours.

AI Changes the Equation

Traditional agencies take months to deliver. We use AI agents at every stage of development — not as a gimmick, but as a force multiplier that lets a small team move like a large one.

What that means for you: faster iterations, lower costs, and software that’s production-ready from the start.

How AI Agents Accelerate Your Build

Design Agent — Iterate via Slack

No more waiting days for mockup revisions. Drop a message in your project’s Slack channel:

“Make the hero section taller, swap the CTA to red, and add a testimonial block below”

Our designer agent processes the request, generates updated mockups, and posts them back — usually within minutes. Approve, request changes, or fork a variation. All in Slack, all tracked.

What the Design Agent handles:

  • Landing page mockups and iterations
  • Component design (cards, forms, navbars, dashboards)
  • Responsive layout variations (desktop, tablet, mobile)
  • Design-to-code export with Tailwind CSS classes
  • Style guide enforcement across all screens

Code Agent — Ship Faster, Break Less

Our development agents handle the parts that slow humans down:

  • Boilerplate generation — CRUD endpoints, database models, auth flows
  • Test writing — Unit and integration tests generated alongside features
  • Code review — AI catches bugs, security issues, and style violations before human review
  • Refactoring — Automated cleanup of tech debt as the codebase grows
  • Documentation — API docs, README files, and inline comments generated automatically

The result: engineers spend their time on what matters — architecture decisions, business logic, and user experience.

Deploy Agent — PR Previews on Every Push

Every pull request gets its own live environment with a unique URL. Share it with stakeholders, test on real devices, get feedback in hours instead of weeks.

  • https://your-app-pr-42.joallt.com — frontend preview
  • https://your-app-api-pr-42.joallt.com — API preview
  • Isolated database branch (via Neon) — no shared state, no data collisions

Merge the PR and it’s live in production. Zero-downtime. Automated rollback if health checks fail.

Our Stack

We’re opinionated about quality, flexible about tools:

  • Frontend: React, Next.js, Astro, Tailwind CSS
  • Backend: Python (FastAPI, Django), TypeScript (Node.js)
  • Mobile: SwiftUI (iOS), React Native
  • Database: PostgreSQL (Neon), Redis, DynamoDB
  • Infrastructure: AWS, Terraform, Docker, Kubernetes
  • AI Tooling: Claude, MCP servers, custom agents

The Process

  1. Discovery — We understand your business goals, users, and constraints
  2. Architecture — System design before a single line of code
  3. Sprint — AI-accelerated development with daily commits, PR previews on every push
  4. Review — Designer agent iterates visuals in Slack, code agents catch issues in PRs
  5. Launch — Zero-downtime deployment to production infrastructure
  6. Operate — Hand off to our DevOps and SRE agents for 24/7 monitoring

Every app we build is ready for the next step: managed hosting and AI-powered operations by our agents.
