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 am looking for a lead developer to architect and build a scalable "Sustainability-as-a-Service" platform. The core of the product is a high-performance API that will be integrated into the checkout flows of major e-commerce and delivery platforms to facilitate real-time environmental impact (tree planting) with every transaction. The core challenge is two-fold: High-Volume API Integration: We need a robust backend capable of handling thousands of concurrent requests from enterprise-level partners.

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...

It should do the following: 1. Calculate it's own hole specific index for course a golfer has played. Come up with a formula that accounts for average score on each particular hole.

Our live data sits in a PostgreSQL instance and some key queries are beginning to drag. I need you to step in, profile what is happening, and carry out light-touch changes that immediately tighten up performance while outlining any deeper work we should schedule later.

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...

Manejo diariamente grandes volúmenes de consultas de clientes; registro cada caso y luego lo sigo hasta su resolución. Para ello utilizo hojas de cálculo y una base de datos sencilla, pero el acceso se ha vuelto lento y está afectando mi productividad y la calidad del soporte que doy. Quiero que un especialista revise la estructura actual, identifique los cuellos de botella y diseñe una solución que acelere la búsqueda, carga y actualización de la información. No importa si la propuesta implica depurar las hojas de cálculo, normalizar tablas SQL, automatizar procesos con scripts o incluso migrar a otro motor: lo esencial es reducir drásticamente los tiempos de respuesta sin perder la trazabilidad de cada ticket d...

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. I’m looking to invest in taking these validated concepts into new geographies or adjacent markets, fully legally and ethically. You bring your insight and knowledge from building and iterating on these products; I provide funding, commercialization expertise, distribution, and scaling support. What I’m looking for: Products or tools you have built that have measurable traction (active users, engagement metrics, retention, CAC/LTV insights, or other KPIs). 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 ...

I have a website in development and I’m now ready to hand off everything tied to the data layer. The site will run on a MySQL back-end and needs three fully functional forms: a general Contact form, a Member registration form, and a Feedback form. Here’s what I need done: • Design and build the MySQL schema so all form submissions are stored efficiently and can be queried later without performance issues. • Create the Contact and Feedback forms with server-side validation and spam protection. • Build the Member registration workflow and hook it to social media login (OAuth) so users can register or sign in with their preferred network; once authenticated, the profile data should be saved to the members table. • Write the necessary CRUD scripts/quer...

I need an experienced Oracle-centric developer who is equally comfortable in Databricks SQL, MySQL, PostgreSQL, T-SQL and PL/SQL to move several production-grade data sets off Oracle 19c and make them run just as fast—if not faster—on each target platform. Here is what the engagement looks like in practical terms: • Data migration: extract with native Oracle utilities (Data Pump or equivalent), load into MySQL, PostgreSQL and Databricks SQL, and validate row-level parity. • Query optimization: review my current PL/SQL queries, reproduce them on each destination, then tune them until execution times meet or exceed the Oracle baseline. Please capture execution plans and explain any indexing or partitioning decisions. • Stored procedure development: rewrite ex...

I manage the backend of our application in MongoDB and now need a specialist to handle an upcoming data-migration cycle. The goal is to move existing collections to a new cluster, keep every document intact, and minimize downtime for the live service. Here’s what I’m looking for: • Plan and execute the full MongoDB data migration, including export, import, and validation steps. • Set up any necessary staging or temporary environments to ensure a smooth cut-over. • Document the process clearly so I can repeat or audit it later. I’ll provide direct access to the current and target databases, plus a quick overview of our schema. You’ll be collaborating with me—fluency in either French or Arabic is a bonus because those are the primary langu...

I’m building an internal platform called “rail12345” whose sole focus is data management for our rail operations. The core need is a clean, reliable back-end that lets my team capture information quickly, store it safely, and retrieve it without friction. Right now I’m gathering an MVP, so your mandate is to design and implement the data layer, the admin interface, and the basic workflows that make day-to-day updates effortless. While the immediate priority is the data backbone itself, I’m open to layering in extras—report generation, dashboards, or visual analytics—once the fundamentals are rock-solid. You’re free to propose the tech stack; I lean toward widely supported frameworks (think PostgreSQL, MySQL, MongoDB, Django, Laravel, No...
