You will get a focused Django code audit and bug-fix action plan
Project details
Get a clear, senior-level diagnosis before spending more time and money on random fixes.
I will review your Django application, reproduce the reported issue, trace the relevant code and data flow, and identify the root cause. Depending on the package, you will receive a prioritized audit, implementation of a clearly scoped fix, fix documentation, and practical recommendations for performance, security, and maintainability.
This service is ideal for:
• Bugs that are difficult to reproduce or keep returning
• Slow views, APIs, database queries, or background jobs
• Unfamiliar or inherited Django codebases
• Deployment and configuration problems
• Security and reliability concerns
• Teams that need a focused technical second opinion
I work with Python, Django, Django REST Framework, PostgreSQL, Redis, Docker, Linux, and Nginx. I have 10+ years of production experience with healthcare, logistics, kiosk, automation, and business systems where reliability matters.
Scope is confirmed before implementation. If the issue is larger than the selected package, I will document the findings and propose a separate milestone instead of making unsafe changes.

About Hieu
Django Engineer | SaaS MVPs, REST APIs & Legacy Rescue
Vinh, Vietnam - 11:10 am local time
I’m a Python/Django engineer with 10+ years of experience taking business systems from unclear requirements to reliable production software. I can own discovery, architecture, backend development, integrations, deployment, and ongoing troubleshooting.
I can help you with:
• SaaS and business MVPs built with Django and Django REST Framework
• REST APIs, webhooks, payments, and third-party integrations
• Existing Django systems: bug fixing, performance, maintenance, and modernization
• PostgreSQL data modeling and query optimization
• Docker, Linux, Nginx, Redis, and production deployment
• Internal tools, workflow automation, and hardware-connected applications
My production background includes healthcare platforms, smart self-service kiosks, logistics and shipment tracking, booking systems, public-service workflows, and IoT integrations. These are operational systems where reliability, data integrity, and maintainability matter.
What you can expect:
• Practical technical decisions explained clearly
• A realistic scope and milestones before development
• Clean, maintainable implementation
• Proactive communication about risks and tradeoffs
• Ownership from first diagnosis through production release
For a new project, I can turn your requirements into an MVP plan and working system. For an existing project, I can begin with a focused audit or small paid milestone, then recommend the safest next steps.
Send me your current stack, main problem, and desired outcome. I’ll reply with a concrete approach.
