Hej! Jag har läst grundkurs i programmering. I kursen ingår 6 laborationer som är på svenska. Jag lämnade in labbarna för två år sedan och fick komplettering på labbarna. Tyvärr fick jag kompletteringen två år efter inlämning och minns därmed inget utav kursen eller Java och det är därför jag behöver hjälp. Vill du arbeta efter fastpris går det också bra.

Hej! Jag har läst programmeringsgrunder och använt programmet Java. I kursen ingår 6 laborationer (på svenska) som man gör hemma. Jag lämnade in labbarna för två år sedan. Då jag har fått kompletteringen två år senare så minns jag inte något utav kursen eller Java och det är därför jag behöver hjälp. I varje labb finns flera uppgifter och jag behöver någon som kan fixa dessa åt mig. Vill man arbeta efter fastpris går det också bra. Mvh Hanna

I’m building a new social-networking experience and need someone who can own both the native Android code and the complete mobile UI/UX. The app will run only on Android and must be developed natively, so Kotlin or Java inside Android Studio is expected. Here’s what I’m looking for: • Translate my rough sketches and feature list into a full UI/UX flow—from user journeys and wireframes to high-fidelity, Material-You-ready prototypes. Figma, Sketch or Adobe XD is fine as long as the hand-off is clean. • Code the core social features natively: onboarding, live feed, profile, in-app chat, push-notification settings and a lightweight post editor. Modern architecture (MVVM with Jetpack components, or your preferred clean pattern) and performance optim...

My React/Java-based web application is currently deployed on Replit, database and all. I now need the entire workload moved—server code to Google Cloud Platform and data to Supabase—while keeping everything running exactly as it does today. The move is time-sensitive, so I’d like the migration completed as soon as possible. I will not give you access to the Replit project, the domain, and any existing environment variables. Expectation is to connect on remote and guide me execute it: • Create or configure the GCP project, set up the appropriate hosting service (Cloud Run, App Engine, or another option you recommend), and point the domain with HTTPS enabled. • Spin up a Supabase instance, migrate the existing data, adjust connection strings, and con...

...day-to-day. The immediate focus is front-end development, so you’ll be steering our React and layers—building reusable components, wiring pages to the router, and tightening up state management. While the UI comes first, we will also expose fresh endpoints as we go; you’ll help shape the Node.js / API that feeds those screens. We already have a rough domain model running in Java micro-services, so expect to consume and occasionally extend those services rather than start from scratch. Clean, well-tested code, Git-based collaboration and clear commit messages are essential because we’ll be working side-by-side and merging often. Deliverables (acceptance criteria) • Pixel-perfect React/ pages that match Figma references and render responsively. ...

...core objective is straightforward: design and code an engaging, modern-looking Android application that lets users create profiles, follow one another, post updates (text, photos, or short videos), and interact through likes and comments. I have wireframe sketches that outline screen flow, but I’m counting on you for UI refinement, smooth navigation, and selecting the right tech stack—Kotlin or Java on Android Studio is fine as long as the final build is stable and future-proof. Robust back-end thinking is important too; whether you prefer Firebase, AWS Amplify, or another scalable service, please outline how you’ll handle user authentication, real-time feed updates, and media storage. To keep us focused, here’s what I expect at each milestone: • In...

I’m ready to move from concept to code on a Java web application and I need a developer who feels at home in JavaServer Faces. The entire project will live in the Java EE ecosystem, so comfort with standard servlet containers, JDBC or JPA for data access, and front-end component libraries such as PrimeFaces or OmniFaces will be important. Here’s what I’m looking for you to handle: • Set up the JSF project structure (Maven or Gradle) • Build the core pages and managed beans that showcase best-practice navigation, validation, and session handling • Wire in persistence so the app reads/writes to a relational database (MySQL or PostgreSQL—your recommendation is welcome) • Implement basic security: login, role-based access, and ...

I have an MVP running on Java 17, Spring Boot, REST, and MySQL, and now I need it turned into a production-grade multi-vendor marketplace.

Scope • Upgrade the existing product, cart, order, and payment modules so multiple sellers can manage their own catalogues independently. • Add advanced search functionality—keywords, categories, price ranges, and vendor filters—backed by Elasticsearch (or a comparable search engine) and integrated with Spring Data. • Introduce user reviews and ratings with a moderation workflow surfaced in the Admin panel. • Deliver real-time notifications for order status updates, stock alerts, ...

The program should run natively on Windows (macOS compatibility would be a welcome bonus) and handle core functions such as client records, invoicing, inventory tracking, simple analytics and user-level access control—all within an intuitive, modern interface. My priority is stability and long-term maintainability, so I’d like the codebase written in a widely supported language (C#, Java or Python with a robust GUI framework are all acceptable). A lightweight local database is fine for now, but the architecture should leave room for us to migrate to a cloud-hosted SQL solution later.

You are free to work in Kotlin or Java and may choose the persistence layer that best fits—Room, DataStore, or another solution—so long as the auto-deletion runs reliably in the background (WorkManager or an equivalent scheduler).
