INDEX / AXXTREMELABS · Production software agency · EST. 2024

We ship hard software on real dates.

Web. Mobile. Backend. AI. A senior engineering shop that takes the brief on Monday, scopes it Tuesday, makes the first commit Wednesday — and ships to production in weeks, not quarters. No agency theatre, no sub-contracting, no compromise on craft.

02 / THE NUMBERS

Shipping cadence, not deck cadence.

We measure ourselves on what reaches users — not what reaches a slide. Every number on this page is something we can point at in production.

i 14 production apps shipped
across web and mobile
ii 72h from signed brief
to first PR merged
iii 12wk average cycle from
kickoff to live
iv 100% of work delivered
in-house. no contractors

We are five senior engineers and a designer who all hate the agency model that ships in quarters. So we built one that ships in weeks.

— A.L., founding engineer
03 / CAPABILITIES

Every layer of the stack. None outsourced.

The full surface area of a modern product — interface, infrastructure, mobile, intelligence — built by the same six engineers, in the same room.

01 FRONTEND ENGINEERING

Interfaces that don’t feel templated.

React, Next.js, Svelte, Astro, Vue. Server components, edge runtimes, streaming. We treat the browser like an application platform — not a rendering target.

  • React
  • Next.js
  • Svelte
  • Astro
  • Vue
  • TypeScript
  • Tailwind
— every pixel earns its place.
02 MOBILE DEVELOPMENT

Cross-platform when it fits. Native when it doesn’t.

Flutter for shared codebase velocity. Native Swift & Kotlin when the feature pushes against platform limits — calls, AR, low-level audio, background workers, secure enclaves.

  • Flutter
  • Swift
  • SwiftUI
  • Kotlin
  • Jetpack Compose
  • WebRTC
— single codebase. both stores. day one.
03 BACKEND & INFRA

The plumbing the user never sees, never notices.

Postgres-first. Node, Go, Rust. Realtime with WebSockets & SSE. Queues, workers, jobs, search. Row-level security by default — every check enforced at the database, not the client.

  • Postgres
  • Node.js
  • Go
  • Rust
  • Redis
  • Supabase
  • Cloudflare
— infra clients forget about because it just works.
04 AI / RAG SYSTEMS FEATURED

Retrieval that actually retrieves.

Custom RAG pipelines, hybrid search, reranking, evals. Vector stores, chunking strategies, citation graphs, agentic workflows. Not the LLM wrapper your last contractor shipped.

  • OpenAI
  • Anthropic
  • LangChain
  • LlamaIndex
  • Qdrant
  • Pinecone
  • pgvector
— evals as a first-class deliverable.
05 MOTION & ANIMATION

Movement with a job to do.

GSAP, Framer Motion, Lottie, SVG, WebGL when it earns it. We use motion to make the interface legible, not to dress it up. The best animation is the one the user never thinks about.

  • GSAP
  • Framer Motion
  • Lottie
  • Three.js
  • Rive
— intentional, never decorative.
06 DESIGN SYSTEMS

Tokens to themes. Three direction options, day one.

We treat the design system as production code. Variables, components, tokens, themed surfaces — versioned, typed, tested. Switchable themes ship with the app, not after it.

  • Figma
  • Tokens Studio
  • Storybook
  • Radix
  • shadcn
— design that scales with the codebase.

05 / PROCESS

How we go from brief to production.

Most agencies run a discovery phase that takes longer than our first release. The cadence below is the default — we’ve held it on every engagement we’ve taken on.

  1. 01 DAY 0

    Brief.

    60-minute call. You describe the product, the users, the deadline. We listen, push back where we should, and leave with a one-pager scope you sign off on by end of day.

    • One-page scope
    • Fixed price
    • Signed same-day
  2. 02 48 H

    Architecture.

    Stack, schema, screens, services, deploy targets. You get a technical brief and three visual directions — themed, switchable, ready for production from day one.

    • Tech brief
    • 3 visual directions
    • Stack locked
  3. 03 72 H FIRST COMMIT

    Build starts.

    Repo, CI, environments, design system, first interactive screen. Within 72 hours of signing the brief, code is on main and a build is shareable with your team.

    • Repo + CI
    • Design system
    • Shareable build
  4. 04 DAILY

    Ships every day.

    Daily deploy to staging. Weekly milestone review. Loom walk-through of every meaningful change. You are never more than 24 hours behind the latest build.

    • Daily deploys
    • Weekly reviews
    • Loom walkthroughs
  5. 05 ~12 WK

    In production.

    Stores. Domain. Analytics. Monitoring. Docs. Handoff. We can stay on retainer for the next quarter, or close the engagement and hand the keys to your in-house team.

    • Stores live
    • Monitoring
    • Full handover
06 / WHY AXXTREMELABS

The difference shows up in the diff.

i

Seniors only.

Every engineer on every project has shipped production software at scale. No junior taping on top of senior architecture, no outsourced overflow. The person on your standup is the person writing the commit.

ii

Fixed price, fixed date.

We scope it. We price it. We hit the date. No T&M, no change-order theatre. If we miss, that is on us — and we’ve never missed.

iii

Production, not prototype.

"MVP" is not in our vocabulary. Everything we hand over has monitoring, error tracking, CI, tests on the load-bearing paths, and a real handover document. We hand back code your team can actually inherit.

iv

Your codebase, day one.

The repo lives on your organisation from the first commit. You own the keys to every cloud account. We do not introduce proprietary glue. If you replace us tomorrow, you keep shipping.

07 / START A BRIEF

Got something hard to build?
We’d like to hear about it.

Tell us what you’re shipping, when you need it, and what the hard part is. We’ll respond inside one business day — and if we can’t take it on, we’ll point you at the people who can.

  • Response inside 24 hours
  • Fixed price after the brief call
  • First commit inside 72 hours of signing
