Capabilities

One studio for the whole AI product stack

Models are only one part of the product. We handle the data pipelines, apps, infrastructure and UX around them, so what we build works in production.

AI & Machine Learning

LLM apps, agents, RAG and custom models, built for production, not just demos.

Web Development

High-performance web applications on modern, type-safe stacks.

export default async function Page() {
  const data = await ai.run()
  return <Dashboard data={data} />
}

Mobile App Development

Native and cross-platform apps people actually keep on their phones.

Cloud & DevOps

Scalable infrastructure, CI/CD and GPU-ready platforms.

Book an AI Discovery Sprint

In 1–2 weeks we check feasibility on your own data and hand over a working prototype with a clear roadmap.

How it works
How we work

From idea to production, in weeks

A delivery process built for AI's uncertainty: validate early on real data, then build in short, demo-able increments.

  1. 01
    Week 1

    Discover

    We dig into your goals, users and data, and pin down where AI and software create measurable value.

  2. 02
    Weeks 2–3

    Prototype

    A working prototype on your real data, so decisions are made on evidence, not slideware.

  3. 03
    Sprints

    Build

    Weekly demos, typed codebases, automated tests and evaluations for every model-driven feature.

  4. 04
    Ongoing

    Launch & scale

Why 305Coders

Senior engineers, not slideware

We work like an in-house product team: small, senior and accountable for results. You get working software every week and a codebase your team can take over.

The 305Coders team collaborating
01

Production over prototypes

Demos are easy. We design for reliability, observability and cost from day one.

02

Senior, small teams

You work directly with the engineers building your product, not a layer of account managers.

03

Your data stays yours

Privacy-first architectures, least-privilege access, and clear ownership of code and IP.

04

Measured outcomes

Every AI feature ships with evaluations, so quality is a number, not a feeling.

Instant estimate

FAQ

Questions, answered

Mostly applied AI inside real products: assistants and copilots, retrieval over company documents, document and data extraction, agent-driven workflow automation, and predictive models. If it needs to run reliably for real users, it is in our wheelhouse.
