The core architecture of my Pharmacy/Retail ERP is already in place; what remains is the last mile. I need the final modules wired up, all lingering data-sync problems resolved, the interface polished for smoother user journeys, and overall performance tightened. Key pain points to tackle: • Data sync fails between devices and back-office database • UI/UX inconsistencies that slow daily operations • Response times that need clear performance optimisation Once those issues are closed, the system must be packaged for both Android and PC—each deployment carries equal weight. I expect a Play-Store–ready APK and a stable desktop installer, both drawing from the same code-base where possible and fully tested end-to-end. Acceptance criteria • Remaining modules fully operational and integrated with existing core • Zero unresolved sync errors after stress testing • Clean, intuitive UI across all screens • Average screen load under two seconds on mid-range hardware • Signed Android APK plus desktop installer delivered with setup documentation If you are comfortable jumping straight into an existing codebase, tightening loose ends, and seeing the product through to dual-platform release, let’s move forward quickly.
