Why Python for your business

One language for backend, data, and AI.

Talent

Deep, founder-vetted talent

Python has one of the largest developer communities in the world, and we filter it hard. Every engineer is founder-vetted against a high bar, so you get people fluent in both backend systems and AI, not generalists learning on your project.

AI-ready

The language of AI and ML

PyTorch, scikit-learn, and LangChain make Python the default for ML pipelines and LLM features. We have shipped Python ML and data systems since 2017, years before the GenAI hype, so you build production AI with engineers who were doing this before it was mainstream.

Versatile

Backend and data in one stack

Django, FastAPI, and Flask cover full-stack apps, high-concurrency APIs, and serverless functions. One language spans your API layer and your data pipelines, so your team hires against a single skill set.

Pod

A pod matched to your problem

We assemble a self-contained pod around your workload, whether that is an API backend, an ML pipeline, or an AI-powered feature. The right mix of engineers, not a generic bench.

Delivery

A delivery lead on every pod

Each pod ships with an experienced delivery lead who owns scope, quality, and timelines. You get working software every sprint, with monitoring and rollback built in, not bolted on.

Python Development Services services

From SPAs to enterprise dashboards — built to ship fast and stay maintainable.

Backend & API Development

REST and GraphQL APIs built with Django, FastAPI, or Flask. We pick the framework based on your workload: Django for full-stack apps with admin panels and auth, FastAPI for high-concurrency APIs and AI-serving endpoints, Flask for lightweight services and serverless functions. Not a one-size-fits-all decision.

AI & ML Engineering

Production ML pipelines, LLM integrations, and AI-powered features. We build with PyTorch, scikit-learn, and LangChain, then deploy on AWS SageMaker or self-hosted infrastructure. Model training is one thing. Getting it into production with monitoring, versioning, and rollback is what most teams struggle with.

Data Engineering & Pipelines

ETL pipelines, data warehousing, and real-time processing with Apache Airflow, Celery, and Pandas. We build the data infrastructure that feeds your dashboards, ML models, and reporting. Clean data in, usable insights out. No 'data lake' that nobody can query.

Automation & Scripting

Process automation, workflow orchestration, and system integration. Python scripts that replace manual work your team does every week. We have automated reporting pipelines, compliance checks, and multi-system data syncs that saved teams 20+ hours per week.

Legacy Migration to Python

Migrating PHP, Ruby, or Java backends to modern Python. We do this incrementally - running old and new systems in parallel, migrating service by service. No big-bang rewrites. Typical migration: 3-6 months depending on system complexity.

Full-Stack Teams (Python + Frontend)

Python backend paired with React, Next.js, or Angular frontend. One team, shared TypeScript types, unified deployment. Most Python projects need a frontend. We staff both sides instead of making you coordinate two vendors.

Our approach

We build Python systems that survive the gap between prototype and production.

01

Data-First Architecture

Python's strength is data. We design systems around data flows, transformation pipelines, and storage patterns first. Application logic wraps around the data model, not the other way around.

02

Production ML Over Demo ML

Training a model is 10% of the work. We focus on the 90% that matters: serving infrastructure, monitoring drift, versioning models, handling failures gracefully, and retraining pipelines that run without manual intervention.

03

Readable Over Clever

Python rewards readability. We write code that junior engineers can understand and senior engineers can extend. Clever one-liners become maintenance burdens. Clear, explicit code compounds in value over time.

04

Automation as Infrastructure

Python scripts that replace manual work should be treated as infrastructure: tested, monitored, and documented. We build automation that teams can rely on, not fragile scripts that break when someone changes a spreadsheet column.

05

Framework Pragmatism

Django, FastAPI, and Flask each solve different problems. We pick based on your workload and team, not our preferences. Sometimes the answer is all three in the same system, each handling the workload it was designed for.

How we deliver

Working software every sprint — not just progress updates.

01

Architecture & Discovery

1-2 weeks

We map your requirements, data flows, and integration points. You get a technical proposal covering framework selection (Django vs FastAPI vs Flask), database design, API architecture, hosting recommendation, and CI/CD setup. No code until the architecture makes sense.

02

API Design & Data Modeling

1-2 weeks

API contracts documented in OpenAPI spec before a single endpoint is built. Database schema designed, relationships mapped, migration strategy defined. If there is an ML component, we define the model serving architecture here.

03

Development & Iteration

6-16 weeks

Sprint-based delivery with working endpoints shipped every two weeks. Automated tests written alongside features. Your team gets staging access from week one. For AI/ML projects, model training runs in parallel with API development.

04

Load Testing & Hardening

1-2 weeks

Production traffic simulation, bottleneck identification, query optimization, caching layers, rate limiting. For ML endpoints: latency benchmarking, model warm-up strategies, and fallback handling. Nothing ships until it handles your expected load.

05

Handoff & Support

Complete documentation, architecture decision records, and runbooks. For ML projects: model retraining guides and monitoring dashboards. Your team owns the system. Optional support retainer for ongoing work, but no lock-in.

Hire Python Developers

Experienced Python engineers who plug into your team and ship from week one.

Model 01

Dedicated Developer

When your backend or ML roadmap outpaces your team, you get an engineer with 3+ years of production Python in Django, FastAPI, or Flask. API design, data engineering, and cloud infrastructure covered, with AI/ML depth available when you need it.

Best for
Choose this when backend or ML work is ongoing and hiring is slow · 3-month minimum engagement
Model 02

Python Pod (2-4 Engineers + Lead)

When an API or service needs to be owned, not just staffed, a pod takes architecture, implementation, testing, and deployment. Leads and mid-level engineers staffed to your project, so delivery stays accountable.

Best for
Choose this when a service needs full ownership from one team · 6-month minimum engagement
Model 03

Project-Based Delivery

When the scope is defined and you want budget certainty, you get fixed deliverables, agreed milestones, and transparent pricing. Clear API contracts set before the first sprint.

Best for
Choose this when scope and contracts are already defined · scope-dependent

Frequently Asked Questions

It depends on scope. An API backend for a web or mobile app with 10-20 endpoints typically runs $15,000 to $40,000. A data platform with ETL pipelines and dashboards sits in the $40,000 to $120,000 range. AI/ML systems with custom model training, serving infrastructure, and monitoring can run $80,000 to $250,000 or more. Our architecture consultation is free and scopes your specific project.
