I’m looking for a developer who can build a single Android mobile app that pulls together every core activity in our company—task management, CRM, inventory, sales, accounting, and service management—into one smooth experience.company is manufacturing machine as well as doing rental spare and machine business. The heart of the project is an integrated “company management” task module that lets me open tasks, assign them to colleagues, and keep tabs on progress without ever leaving the app. Around that hub, I need tight links to: • CRM for lead capture, follow-ups, and client history • Real-time inventory and stock alerts • Quotation, order, and sales tracking • Basic accounting (invoices, payments, receipts) • Service tickets for post-sale support Your deliverables will be: • Production-ready Android APK and Play Store-ready bundle • Full Kotlin/Java source code with clear structure and comments • A short setup guide plus API or database schema documentation • Two weeks of post-deployment bug support If you have a proven track record building complex, module-driven Android apps and can advise on best-fit tech (Firebase, Room, RESTful APIs, etc.), I’d love to discuss timelines and milestones.
