I’m looking to build a lightweight appointment-scheduling module that clinics and hospitals can run from any browser. The core focus is simple: staff should be able to book, move, or cancel appointments in seconds, and every confirmed booking must automatically trigger an SMS reminder that includes the visit’s date and time, the doctor’s name, and the clinic address. The flow I have in mind: • Receptionist (or doctor) opens a clean calendar view, chooses an open slot, selects / creates the patient, and clicks “Save”. • Behind the scenes the system stores the booking and instantly sends the tailored SMS through an integrated gateway such as Twilio, Nexmo, or any equivalent you recommend. • If the slot is later changed or cancelled, a follow-...

I run a home-grown virtual tabletop simulation and would like to replace the handful of spreadsheets and manual clicks with one cohesive Windows desktop app. The goal is to automate three core areas: resource management, combat resolution, and the various turn-by-turn trackers that keep the session running smoothly. The interface needs to be an intuitive GUI—think drag-and-drop character panes, quick-access buttons for initiative, real-time stat bars, and a clean dashboard where I can toggle optional house-rules on the fly. Under the hood, I need solid data handling so that hit points, spell slots, cooldowns, and inventory stay in sync even when multiple NPCs are involved. If a player swings a sword, I want the dice rolled, modifiers applied, and results logged to the history panel ...

I’m looking for a reliable way to mirror my on-premise SQL database to AWS RDS in real time. The web service you build will capture every change that hits the local tables—customer information, inventory data, and transaction records—then push those changes up to the cloud with minimal latency. My priorities are: • Zero data loss and consistent state between the two stores, even when connectivity drops temporarily. • Latency low enough to feel immediate to downstream apps that rely on the cloud copy. • A straightforward deployment path: I should be able to install the service on a Windows or Linux host beside the local database, point it at the RDS instance, and watch it run. Deliverables 1. Source code for the sync service (language and framewor...

I need a brand-new Microsoft Access file that lets our small church keep all giving information in one place. The database should open with a simple membership form where I can manually add or update each giver’s name, address and contact details. Every giver must have a unique ID so that offerings entered later will always link back to the correct person. A second form will record each offering. When I choose the member’s name, the form should automatically pull in their ID; I then select the fund from a drop-down list that starts with Tithe, Building Fund, Missions, Mercy Ministries and Other. I also need the option to add new fund names on the fly without touching the table design, plus a memo area for special notes. From these two tables I want to run three practical repo...

I work with developers who have built real, client-facing software products or platforms in specific geographies. Many of you have already validated features, adoption, and business models in your markets.

Products that solve real pain points for clients or end-users. Brief description of the tech stack, prototypes, or de...

I want to streamline our hiring pipeline with a simple, focused candidate-tracking tool that does one thing exceptionally well: measure and display time-to-hire. Each applicant should move through configurable stages (applied, phone screen, interview, offer, etc.), and every status change needs an automatic timestamp so the platform can calculate how long each step—and the overall process—takes. A concise dashboard must highlight average, median, and stage-by-stage times, with quick filters by role, recruiter, or date range. I also need the raw numbers exportable to CSV for deeper analysis in Excel or BI tools. Clean UI, responsive design, and a straightforward admin panel for adding roles or editing stages round out the essentials. Deliverables: • Web-based application ...
