## Where most teams are

Python is where most AI and data work happens: LLM pipelines, data processing, integrations and the APIs behind them. Our engineers built the AI and data layer of an analytics app as it grew to 1.5M+ users.

Your AI feature works only in a demo → AI pipelines tested and monitored

Data jobs fail and nobody notices → Data pipelines that run on schedule

Every new integration is a one-off → Integrations built on one clean pattern

Hiring a senior dev would take months → A senior engineer, month to month

## What our Python developers do

### LLM pipelines that hold up

Prompts, retrieval, validation and fallbacks around the model, tested on your real data, so the feature still gives the right answer on the thousandth odd request.

### Agents that write and run Python

Agents on LangChain or LangGraph that plan, write and run Python in a sandbox, behind a FastAPI backend that streams results to your users as the work happens.

### Signals from messy data

Data from your tools, databases and third-party APIs pulled into one clean stream, scheduled, monitored and retried, so the reports and models built on it can be trusted.

### APIs other teams build on

FastAPI or Django services that are documented, versioned and safe to depend on, so your frontend, partners and other products can build on them without things breaking.

## How it works

1. 01

### Pick a tier

Part-time, dedicated or embedded, from $4,000 a month. Tiers differ in hours and in how closely we work with your team.
2. 02

### Onboard fast

No hiring cycle and no months-long ramp: a senior engineer gets into your codebase, data and tools, and joins your standups.
3. 03

### Ship every week

Features, pipelines and fixes. The engineer doing the work is the one on your calls. Change tier or stop any month.

Starting at $4,000/mo

Part-time from $4,000/month, month to month. Not sure which AI ideas are worth building? Start with an [AI audit](https://zeroic.in/services/ai-audit) (from $1,000).

FAQ

## Frequently asked questions

How much does it cost to hire a Python developer?

Our retainers start at $4,000 a month for the part-time tier, month to month. Dedicated and embedded tiers add more hours. Prefer a fixed scope? We also do fixed-price projects, and audits from $1,000.

What kind of Python work do you do?

AI and data first: LLM pipelines, retrieval, data processing, integrations with third-party tools, and the APIs that serve them.

Can you add AI to our existing Python backend?

Yes. We add features such as natural-language search, summaries or agents to products that are already live, and test them on real data before launch.

How quickly can someone start?

Within a week of agreeing the tier. There is no hiring cycle and no months-long ramp.

Do we own everything you build?

Yes, 100%. You own the code, infrastructure, docs and credentials.
