I have already written most of a custom ERP/CRM in Python, but a handful of features and polish tasks are still unfinished and blocking release. The core database schema, main views, and API endpoints are working; what I now need is a developer who can read my existing codebase quickly, identify the gaps, and deliver fully working, production-ready modules. The outstanding items include completing some accounting, inventory, and customer-facing workflows, closing any authentication loopholes, squashing bugs that surface during integration tests, and making sure the system produces clean, exportable reports. You will have access to my current Git repository, schema documentation, and a short list of known issues to start with—beyond that, I’m happy to walk you through the business logic over a brief call so you understand exactly how everything fits together. Please be comfortable working in Python (the entire backend is written in it), writing clear, well-commented code that follows the patterns already in place, and pushing concise, verifiable commits. If you can demonstrate similar projects you have taken to completion, that will definitely help me gauge fit. I am looking to wrap this up quickly, so a focused approach, regular updates, and reliable delivery milestones will be important.

Picking up half-built Python projects is most of what I do. First pass would be reading through your code to map what's there, what's stubbed, and what the data model assumes, before touching anything. Bidding 2,500 INR because the budget range doesn't match a working codebase you want polished properly. At 600-1,500 you get a rushed patch job, not finished features. 4 days: - Day 1: code walkthrough, pinned task list with your priorities - Day 2-3: feature work and API polish - Day 4: testing, fixes, handover notes What's the rough size of the codebase, and which tasks hurt most?

Hi, This looks like a system that’s already well-structured but needs focused completion, validation, and stability before release. I’ve worked closely on ERP/CRM workflows (sales, inventory, and business processes), where the key challenge is usually not just development, but ensuring all modules align correctly and work reliably in real scenarios. I can help review the current system, identify functional gaps, validate workflows, and ensure everything is ready from a business and usability perspective. For implementation and code-level completion, I work with a development team experienced in Python-based systems, so we can move quickly while keeping the structure clean and consistent with your existing codebase. Can you share the priority modules or blockers you’d like to close first?

For your ERP/CRM, I'll: - Audit the existing codebase and map all incomplete modules - Finish accounting, inventory, and customer-facing workflows - Patch authentication loopholes (sessions, RBAC, input validation) - Fix integration test failures systematically - Add clean exportable reports (CSV/Excel/PDF) - Deliver with tests, comments, and concise Git commits I work from your repo, give regular progress updates, and hit milestones. Can we schedule a quick call to walk through the business logic so I can start immediately?

Hi, Completing an existing codebase is a different skill from building from scratch — and it's one I take seriously. I know how to read unfamiliar code quickly, respect existing patterns, and deliver clean additions that feel native to the project. I'm a Python developer comfortable across backend systems, APIs, and database workflows. Here's how I'd approach your project: — Review your Git repo and schema docs before our first call so I arrive with real questions, not generic ones. — Work through the known issues list systematically, closing auth loopholes and integration bugs first. — Complete the accounting, inventory, and customer workflow modules to production standard. — Deliver clean, exportable reports and well-commented code that matches your existing style. — Push verifiable commits with regular progress updates so you always know where things stand. I work best with a clear milestone structure and I won't disappear between deliveries. Happy to jump on a quick call to walk through the business logic. Feel free to message me! Looking forward to helping you get this across the finish line.
