I’m kicking off a brand-new web application and want the entire stack set up from scratch. The backend must be built with Spring Boot, exposing clean REST endpoints and following best practices for security, logging, and testing. Data will live in a relational store—MySQL or PostgreSQL—so the schema, migrations, and repository layer should be wired for one of those engines with minimal friction to switch between them. On the front end I’m open to modern JavaScript frameworks; feel free to propose React, Angular, or another popular choice as long as it integrates smoothly with the Spring Boot API and supports responsive design. Because this is green-field work, the project will move through typical milestones: design, MVP, iterative feature drops, and deployment. I...

I’m building an online marketplace focused on buying and selling property, and the heart of the product is an immersive 3D map that lets users explore listings in a city-scale environment. Every listing should appear as a geolocated object that the user can click to open full details, photos, videos, floor-plans, and any attached documents. Alongside the map experience I also need a full user system: sign-up / log-in (email and social), profile management, saved searches, and dashboard analytics for both agents and private sellers. Key parts of the build • 3D map layer capable of smooth zoom, tilt, and building extrusion––think Mapbox GL, Cesium, or a comparable WebGL approach. • Secure authentication and role-based access so that buyers, sellers, and admins ...

I need a straightforward platform that lets me enter raw exam scores, have them graded automatically, and release the final results to students in a clean, secure interface. The grading engine has to support three schemes out of the box—CGPA, traditional letter grades, and a simple pass/fail toggle—so I can choose the one that fits each course without rewriting formulas every term. Grade boundaries, GPA weightings, and pass thresholds must stay fully editable from an admin panel. Once the marks are processed, the system should publish them to a student-facing portal where each learner can log in and view only their own transcript. A printable report and optional CSV/PDF export will help when we need physical copies or bulk data sharing. Role-based authentication, a small audit...

I have the basic framework of a Python-based web app up and running, but I need a seasoned developer to help me take it over the finish line. The app’s sole focus is data management, and I want it to excel at the three core functions I’ve already planned: Data storage, Data analysis, and Data visualization. Right now the project uses Python 3.11 with Flask, SQLAlchemy, and a PostgreSQL database. The back-end is roughly 70 % complete; models exist, routes are mapped, and authentication is in place. What’s missing are the polished features that turn this code into a product: optimizing queries, refining the analysis layer (Pandas, NumPy), and wiring up interactive charts (Plotly or ) so users can explore results in real time. A light React front end is already scaffolded...

I am building a green-field fraud-detection platform and need an experienced back-end engineer to own the server-side work for the next three months. The stack is .NET (C#), PostgreSQL, and Redis; a separate team will handle the React front end, so your focus stays firmly on the APIs, data layer, and real-time processing pipeline.
