What We Build with Python

From Django SaaS to production ML — Python is our primary stack for data-driven and AI-first products.

AI/ML Systems

LLM & RAG apps, prediction and scoring APIs, computer vision, and MLOps deployed as monitored production services.

FastAPI Backends

High-throughput async APIs with Pydantic contracts, OpenAPI docs, and ML inference endpoints for mobile and SPA clients.

Django Apps & SaaS

Admin-heavy portals, B2B SaaS, and content platforms on Django's ORM, auth, and admin plus Django REST Framework.

Data Pipelines

Ingestion, cleaning, feature stores, and scheduled jobs with Airflow/Prefect feeding analytics and models.

Automation & Integrations

Python scripts and services that connect systems, scrape and process data, and automate operations.

Full-Stack Delivery

Python plus React or Flutter from one team — architecture, build, QA, deploy, and post-launch support.

Why Python

Python wins when data, ML, or Python-native ecosystems are the product — not when you only need a brochure site.

AI-First Products

AI
Native

LLM, RAG, and prediction features live natively in Python — no cross-language glue between the model and the app.

Data-Heavy SaaS

Data
Core

Django and FastAPI power analytics-driven products where pipelines and dashboards are core to the offering.

API-First Backends

1 API
Many clients

One FastAPI or DRF backend serves web, mobile, and ML inference without duplicating business rules.

Automation at Scale

Auto
At scale

Python services orchestrate scraping, processing, and system integrations that would break a spreadsheet.

Common Challenges

Python Product Risks We Prevent

Where data and AI products go wrong before a good team is involved.

Notebooks that never ship

Promising ML prototypes stall without serving, evaluation, and monitoring.

Wrong framework for the job

Django forced onto async/ML workloads — or FastAPI without the admin you needed.

No evaluation on AI features

LLM output looks great in a demo and fails silently in production.

Inherited Python debt

Untyped, untested code that's scary to extend without an audit.

Why Python Is the Right Stack for Data & AI Products

Python is the default language of machine learning, data science, and automation — and a first-class choice for web APIs and applications through Django and FastAPI. When your product depends on models, data, or scientific libraries, Python removes the cross-language friction that slows other stacks.

We choose Python when AI/ML sits at the core, when data pipelines drive the product, or when your team is Python-native. Django gives us batteries-included web and admin; FastAPI gives us async speed and ML serving. Used well, Python accelerates delivery. Used poorly, it accumulates debt. Our job is the former.

GreeLogix is a product-minded Python agency — not a body shop. We pick Django or FastAPI per workload, quantify hosted-vs-custom model trade-offs, and instrument ML with evaluation and monitoring before launch. That discipline is why clients hire us for rescue work as often as greenfield builds.

  • Python 3.12 with Django 5, FastAPI, and Django REST Framework
  • PostgreSQL, Redis, Celery, and Docker deployment patterns
  • PyTorch, scikit-learn, LangChain, and vector databases for AI/ML
  • QA and code audit from the same organization

Industries We Serve with Python

Our Python practice spans verticals where data, ML, and automation drive revenue — not brochure websites.

  • AI-first products and data-driven SaaS
  • Fintech scoring, risk, and analytics platforms
  • Healthcare and life-sciences data tools

Frequently Asked Questions

Answers to the buyer questions we hear most before a project starts.

What kinds of products do you build with Python?
We use Python for web apps and SaaS (Django), high-throughput and ML-serving APIs (FastAPI), AI/ML features (LLM, RAG, prediction, computer vision), data pipelines, and automation. It works especially well when data or machine learning sits at the core of the product.
Django or FastAPI — which do you recommend?
Django when you want batteries-included web apps with admin, ORM, and auth. FastAPI when you need async performance, ML inference, or API-first microservices. Many products use Django for the app and FastAPI for inference — we pick per workload in discovery.
Do you build AI and machine learning in Python?
Yes — it is a core specialty. LLM and RAG applications, prediction and scoring APIs, computer vision, and MLOps deployed as monitored production services. We are pragmatic about hosted vs custom models and quantify the trade-off first.
Can you work with an existing Python or Django codebase?
Yes. We take over existing projects for feature delivery, cleanup, performance tuning, version upgrades, and ongoing maintenance. We usually start with a quick technical audit before recommending next steps.
Do you only provide developers or can you deliver the full project?
Both. We provide dedicated Python developers for augmentation or handle the full project from discovery and architecture through build, QA, deployment, and post-launch support.
How much does Python development cost?
Audits and PoCs run $2,500–$12,000. Scoped MVPs and modules typically $15,000–$60,000. Dedicated Python engineers $5,000–$15,000/month per senior developer. Final quotes follow a discovery call once modules and ML scope are defined.
How long does a Python MVP take?
A focused Python MVP with auth, one core workflow, and admin usually ships in 6–10 weeks. Adding an ML feature or mobile client adds 2–4 weeks. Rescue and migration projects vary — we map phases in week one.
What Python stack do you use?
Python 3.12, Django 5 and Django REST Framework, FastAPI with Pydantic, PostgreSQL, Redis, Celery for async jobs, PyTorch/scikit-learn for ML, and Docker-based deployment — paired with React or Flutter when the product needs modern frontends.
How does Python compare to Node.js or Laravel?
Python leads for AI/ML, data, and scientific workloads and for Python-first teams. Node.js wins for JS-only teams and heavy realtime. Laravel wins for PHP teams and Cashier/Filament billing. We build all three — see our comparison guides for a neutral breakdown.
Do you offer Python developers in US or UK timezones?
Yes. Our Lahore team overlaps US, UK, AU, and Gulf business hours, with daily standups in your timezone for dedicated engagements.
Do you test Python apps and APIs before launch?
Yes. Every engagement includes QA on critical paths — auth, billing, permissions, and integrations — with pytest in CI. We also offer dedicated API testing as a separate practice.
Can Python power mobile app backends?
Absolutely. FastAPI and Django REST Framework are excellent backends for Flutter and React Native apps. We often deliver a Python API plus mobile clients from one team so everything shares one source of truth.
