Django Upgrade, Modernization & Rescue for US Startups & SMBs
MicroPyramid is a Django modernization company that audits, rescues, and upgrades legacy Django and Python apps for US founders and engineering teams (Django 2/3 to 4/5, Python 2 to 3, performance and security fixes) with first improvements shipped in weeks, without breaking production. Every engagement is audit-first, and you own all code and IP.

What we fix & build.
Five Django engineering services, each targeting a specific problem that holds products back
Codebase Review & Audit
Systematic review of your Django codebase (architecture, dependencies, performance, security, and test coverage) with a prioritized improvement plan.
- Architecture & structure review
- Security vulnerability scan
- Performance bottleneck analysis
Performance Optimization
Fix slow queries, missing indexes, N+1 problems, cache inefficiencies, and async bottlenecks that are slowing down your application.
- Query optimization & indexing
- Redis caching strategy
- Async & background task tuning
Security Hardening
Dependency audits, OWASP vulnerability fixes, authentication review, secrets management, and CSRF/injection protection improvements.
- OWASP top-10 fixes
- Auth & session security
- Secrets & environment hygiene
Architecture Cleanup
Refactor spaghetti code, improve separation of concerns, decouple business logic, and build a test suite that gives your team confidence to ship.
- Modular architecture design
- Test coverage improvements
- Dependency decoupling
Rescue & Recovery
Take over a struggling project (inherited codebase, burned-out freelancer handover, or post-launch instability), stabilize it and build a clear path forward.
- Rapid triage & stabilization
- Technical debt mapping
- Handover & documentation
Best fit for
- Django or Python products on older versions, fragile dependencies, or risky deployment setups
- teams inheriting a messy codebase that blocks feature work and slows delivery
- products with security, performance, or maintainability issues that need expert triage first
- founders who need a clear audit and roadmap before deciding between cleanup, modernization, or rebuild
Not the right fit when
- greenfield products with no legacy constraints
- engagements looking only for junior ticket execution without architecture or cleanup ownership
- projects that need a broader cross-stack migration rather than Django-specific modernization
- teams unwilling to invest in testing, cleanup, or staged rollout before shipping more features
If the problem is broader than Django alone, review Modernization & Upgrades.
How a sprint works.
Every engagement starts with a codebase audit, so you know exactly what you're dealing with before committing to a fix

Straight answers to the questions US founders and CTOs ask before starting a Django modernization, upgrade, or rescue.
What drives the cost of modernizing or upgrading a Django application?
Cost is driven mostly by how outdated the code is, dependency and breaking-change risk, current test coverage, and how much architecture cleanup the app needs. Rather than quote blind, we start with a fixed-scope Codebase Audit Sprint that gives you a concrete estimate, prioritized roadmap, and risk map before you commit to any fixes.
How long does a Django version upgrade take?
It depends on how many versions you are jumping, how many dependencies are abandoned, and how much test coverage already exists. The audit maps each of those and gives you a sequenced timeline and fixed estimate before any upgrade work starts. We then step through versions incrementally, using AI-assisted refactoring with engineer review on every change, so each step is verifiable.
Will upgrading Django break my production application?
Not when it is done audit-first. We map dependency and breaking-change risk before touching code, add or strengthen the test suite, upgrade incrementally across minor versions rather than in one leap, and deploy in staged rollouts. The goal is a modernized app that ships safely, not a risky big-bang rewrite.
Can you upgrade an old Django 1.x/2.x or Python 2 codebase?
Yes. We regularly take Django 1.x/2.x and Python 2 codebases to current Django 4.x/5.x on Python 3, stepping through intermediate versions, replacing deprecated APIs and abandoned dependencies, and adding the test coverage that makes each step verifiable.
Do I need a full rewrite, or can the existing Django app be saved?
Most Django apps can be rescued and modernized without a full rewrite. A rewrite is the exception, not the default. The Codebase Audit tells you honestly which path is cheaper and lower-risk: incremental modernization, targeted refactor, or (rarely) a staged rebuild. You get the recommendation with reasoning before committing.
Who owns the code and intellectual property?
You do. You keep full ownership of all source code, IP, and infrastructure, and we work in your repositories and deploy to your cloud accounts. We sign NDAs and IP-assignment agreements before work begins.
Can you add AI features to an existing Django app while modernizing it?
Yes. Once the foundation is stable we can embed retrieval-backed (RAG) search, in-app copilots, and AI assistants into your Django product, grounded in your own data, with citations and safe fallbacks. See our AI feature development work for how we add these safely.
