    Our in-house document management platform has been running smoothly on a C#/.NET stack, MS SQL Server, and AWS for several years, but the developer who built and nurtured it is leaving. I need someone who can step in right away, understand the codebase, and keep the application stable and performant. The immediate focus is routine maintenance—diagnosing and fixing any bugs that surface and squeezing better performance out of the code, database, and AWS resources. I don’t have a current list of issues, yet I suspect the usual mix of edge-case errors and slow queries will emerge once you start profiling the system. You’ll get full access to the Git repository, SQL scripts, and our AWS environment (EC2, RDS, S3). A thorough walkthrough with the departing developer can be a...

    I need an Oracle APEX application that streamlines one of our internal business processes from start to finish. The focus is a clean, permission-based workflow that automatically routes each new record through a multistep approval cycle. At a minimum the app must: • Capture data through responsive APEX forms • Trigger an approval workflow the moment a record is submitted • Update status, log every decision, and prevent users from skipping steps When an approver acts, the system should move the item to the next stage, send the correct email or in-app notification, and maintain an audit trail we can export to CSV or view in a dashboard. I will provide table definitions and sample data; you’ll translate that into APEX pages, processes, and any PL/SQL packages req...

    I’m kicking off a new healthcare patient-management system and the first critical piece is a rock-solid, compliant data layer. The entire scope at this stage revolves around database management—designing, building, and documenting a schema that can safely house patient records, appointments, clinical notes, and billing details while meeting HIPAA-level security expectations. Here’s what I need from you: • Analyse typical patient-care workflows and translate them into an efficient relational model. • Deliver an ER diagram, a fully normalised schema, and an indexing strategy suitable for high-volume queries. • Implement the model in the SQL engine you recommend (PostgreSQL, MySQL, or MS-SQL are all fine if they cover encryption-at-rest, robust backup, a...

    Tablet-Based IoT Tool Inventory

    I need a purpose-built IoT inventory platform that keeps every tool in my auto shop accounted for and instantly searchable from a tablet on the workshop floor. The interface has to feel at home on an iPad or similar device—large touch targets, quick loading times, and an offline-tolerant design so my technicians can still work if Wi-Fi drops for a moment. Core workflow Technicians will scan or tap a tagged tool, confirm where it is going, and the system updates our stock level and location log. When a tool hasn’t been returned or its quantity falls below a preset threshold, the platform should flag it on the dashboard and optionally push a notification. I’m open to common tag technologies such as BLE or passive RFID; the software just needs a clean way to map tag IDs to ...
