The central hub for everything we build with Python — Django web apps and SaaS, FastAPI backends, AI/ML features, data pipelines, and dedicated engineering teams with global timezone overlap.
Django + FastAPI · Production AI/ML · 150+ products shipped · Lahore team, US/UK/AU clients
30 minutes · Senior engineer · No commitment
From Django SaaS to production ML — Python is our primary stack for data-driven and AI-first products.
LLM & RAG apps, prediction and scoring APIs, computer vision, and MLOps deployed as monitored production services.
High-throughput async APIs with Pydantic contracts, OpenAPI docs, and ML inference endpoints for mobile and SPA clients.
Admin-heavy portals, B2B SaaS, and content platforms on Django's ORM, auth, and admin plus Django REST Framework.
Ingestion, cleaning, feature stores, and scheduled jobs with Airflow/Prefect feeding analytics and models.
Python scripts and services that connect systems, scrape and process data, and automate operations.
Python plus React or Flutter from one team — architecture, build, QA, deploy, and post-launch support.
Python wins when data, ML, or Python-native ecosystems are the product — not when you only need a brochure site.
LLM, RAG, and prediction features live natively in Python — no cross-language glue between the model and the app.
Django and FastAPI power analytics-driven products where pipelines and dashboards are core to the offering.
One FastAPI or DRF backend serves web, mobile, and ML inference without duplicating business rules.
Python services orchestrate scraping, processing, and system integrations that would break a spreadsheet.
Where data and AI products go wrong before a good team is involved.
Promising ML prototypes stall without serving, evaluation, and monitoring.
Django forced onto async/ML workloads — or FastAPI without the admin you needed.
LLM output looks great in a demo and fails silently in production.
Untyped, untested code that's scary to extend without an audit.
One senior team across web, APIs, and production machine learning.
Hosted vs custom models quantified; monitoring built in from day one.
We pick Django, FastAPI, or both — not one framework for everything.
Tests on critical paths and eval sets for ML before launch.
“What a 70-engineer team could not deliver, a small senior team at GreeLogix shipped. The app went from stuck to live across mobile, web, and backend.”
At-a-glance scope, pricing tiers, delivery timelines, engineering tradeoffs, and decision criteria for technical founders and product leaders.
Python development services from GreeLogix cover Django web apps and SaaS, FastAPI and Django REST APIs, AI/ML features (LLM, RAG, prediction, vision), data pipelines, and legacy modernization — built with Python 3.12, structured architecture, QA gates, and production deployment support.
GreeLogix pricing tiers: Python Audit & PoC: $2,500 – $12,000 — Codebase or AI feasibility review, architecture map, and a working proof-of-concept for new ML features or stalled Python apps. Python MVP / Module Build: $15,000 – $60,000 — Scoped Python delivery — Django or FastAPI apps, APIs, and ML services — with weekly demos and QA gates. Dedicated Python Team: $5,000 – $15,000 / mo — Embedded senior Python & ML engineers in your repo with US/UK/AU timezone overlap.
Python audit or PoC: 1–3 weeks. MVP with auth and core workflow: 6–10 weeks. Production ML: 6–12 weeks. Enterprise modules: phased delivery over quarters.
Compare delivery models, cost profiles, and engineering tradeoffs before committing resources.
| Option / Approach | Best When | Primary Tradeoff / Risk | Recommended Fit |
|---|---|---|---|
| Node.js backend | JS-only team or heavy realtime/WebSocket throughput from day one | Requires ongoing internal technical governance, architectural oversight, and dedicated maintenance resources. | Self-directed internal teams |
| Laravel / PHP | PHP team or Cashier/Filament billing ecosystem preference | Requires ongoing internal technical governance, architectural oversight, and dedicated maintenance resources. | Self-directed internal teams |
| No-code / hosted AI SaaS | Fast prototype only — plan a Python rebuild before production scale | Scalability bottlenecks, vendor lock-in, architectural rigidity, and substantial technical debt before handling production traffic. | Early validation & UI experiments |
| GreeLogix Pod | Accountable production delivery with senior engineers, weekly demos, and fixed milestone velocity. | Requires active product owner for weekly sprint reviews and scope alignment. | Production & Scaling (Recommended) |

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.
Our Python practice spans verticals where data, ML, and automation drive revenue — not brochure websites.
Whether you need a greenfield MVP, dedicated engineers, an AI/ML build, or ongoing maintenance — this hub connects every Python service we offer.
Answers to the buyer questions we hear most before a project starts.
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 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.
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.
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.
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.
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.
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.
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.
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.
Yes. Our Lahore team overlaps US, UK, AU, and Gulf business hours, with daily standups in your timezone for dedicated engagements.
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.
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.
We review goals, data, workflows, integrations, and whether Python — and which framework — is the right fit.
You get modules, data model, ML plan, sprint schedule, and fixed-milestone pricing options.
