Jeg har vil ha et Bitcoin kasino, jeg har for øyeblikket kun muligheten til å betale via PayPal. Jeg har også muligheten til å øke budsjettet underveis dersom det er nødvendig. Jeg kan kun Java selv og er veldig ny innen PHP og generell utvikling av nettsider, så jeg setter pris på enkel og ryddig kode ettersom jeg skal lære meg mer etterhvert som tiden går.

A REST or GraphQL API layer is required so I can hook in external KYC, payment gateways and analytics. Acceptance criteria 1. I can re-skin the UI via configuration files or a theme layer without touching source code. 2....

...micro-transaction models, yet I need an experienced developer who can translate those ideas into a market-ready APK, guide me through Google Play submission, and advise on revenue tactics such as in-app purchases and ads. We’ll start by shaping the minimum viable product together, then iterate based on early user feedback so we can reach break-even quickly and scale. Clean, well-commented Kotlin or Java code, crash-free performance across the latest Android versions, and clear documentation are must-haves. If you’ve already shipped profitable Android apps and can point to metrics that prove it, I want to work with you....

We maintain a Java-based NIBSS NIP integration that relies on two web services for PGP encryption and decryption. The companion service is healthy, but the NIP-facing service suddenly began misbehaving on 12 / 05 / 2025 after running smoothly for seven years. Since that date we see outright encryption failures as well as sporadic communication errors, and on rare occasions the partner bank reports decryption problems on their side. I need a seasoned Java developer who understands PGP internals and secure web-service plumbing to: • reproduce the fault locally (I can provide logs, sample payloads, keystores, and the last known good tag) • pinpoint the root cause—whether it is key corruption, library regression, JVM upgrade side-effect, or message framing iss...

...fresh social-media idea into a full Android application and need an experienced mobile developer to guide the project from concept to Google Play release. The core focus is an engaging, modern social platform where users can register, create profiles, post content, follow others, and interact through likes, comments, and real-time notifications.

...smooth user-profile flow: new users must be able to register, sign in, view, and edit their own profile. Aside from that, the interface can stay minimal for now; clean, extendable code is what matters most. The build should target Android only. Kotlin plus the current Android Studio toolchain is my first choice because of its modern language features and Jetpack support, but I am open to well-argued Java solutions. For data persistence and authentication you may suggest Firebase or another secure, mobile-friendly backend as long as setup instructions are part of the handover. Deliverables I expect: • A release-ready APK I can install on any recent Android device • The complete, organised source code with clear comments • A concise README covering environment ...

Deliverables • Full Android Studio project with readable Kotlin or Java source • Signed APK ready for side-loading plus instructions for Play Store submission • Brief setup guide covering backend, push notifications, and encryption keys • Two weeks of post-delivery support t...

Our taxi-hailing product runs on a Java backend that now requires ongoing care. The mobile flutter apps and website are functioning well, so your focus will be the server side only. Key tasks I need handled: Stability improvements, bug fixes and making it all more efficient. Developer needs to be skilled in AI, Serverside coding, flutter and general software development.

I have a fully working platform with a Django backend, an Android client written in Java, and an iOS client in Swift. I now need a complete visual overhaul—both user interface and branding elements—across every layer. Alongside the new look, I also want to strengthen the product with enhanced security features, smoother user navigation, and fresh integrations with third-party services that make sense for the stack. You will take the existing source code, apply the new designs, handle any code-level refactoring that the security and navigation changes require, update the API or middleware for the new integrations, and then compile, test, and publish the builds to Google Play and the Apple App Store under my accounts. Please send a detailed project proposal that shows ho...

I have a plain Java project open in Eclipse and a folder full of external JAR files that must be referenced. I’m looking for someone to walk me through, or quickly do for me, the exact Build Path configuration steps so that Eclipse resolves every class without warnings. The task is straightforward: import the external libraries, update the Build Path, confirm the project compiles-runs, and leave me with a repeatable set of instructions (screen-shots or a short doc) so I can add more JARs the same way in the future. A brief remote session is fine, or clear written steps—whichever you prefer—as long as the project is clean and executable when we finish.

I need a skilled Android developer to turn my USHA SEMBAKO concept into a fully functional mobile application. The project is strictly mobile-focused—no web or iOS version is planned at this stage—so your expertise should centre on the Android SDK, Kotlin or Java, responsive UI design, and smooth integration with modern Android libraries. Scope • Translate my feature list and wireframes (shared after kickoff) into clean, maintainable Android code. • Build intuitive screens that follow current Material Design guidelines. • Connect the app to a lightweight back-end or cloud service of your choice for data persistence—Firebase, Supabase, or a REST API are all acceptable as long as they keep future scaling in mind. • Hand over full source c...

Our next mobile release is on hold until five high-priority bugs are resolved on both Android (Java/Kotlin) and iOS (Swift). I need someone who can jump into the codebase right away, trace the problem areas independently, and ship production-ready fixes. Scope You’ll work on both platforms simultaneously; the most critical symptom on iOS is a crash that slips past TestFlight. Source access is already prepared, and while documentation is spotty I’m available for quick video calls whenever clarification is needed. You’ll also have a direct Slack line to our backend engineer for anything API-related. Deliverables • Diagnose the root cause of each of the five reported issues on Android and iOS • Commit clean, well-commented patches that compile without warn...

The goal is to release an Android mobile app that works as a full-featured freelance job marketplace. Users must be able to register, post or browse gigs, negotiate terms, and receive payments directly through the platform—everything required for freelancers to turn the app into a reliable income source. Because Android is the only targeted system for this first release, I’m open to Kotlin, Java, Flutter, or React Native—whatever lets you deliver a smooth, modern UI plus scalable back-end integration. The core focus is clear: a streamlined, secure marketplace experience rather than a repurposed e-commerce or subscription tool. Key deliverables • Production-ready APK and Play Store–compliant package • Complete source code with build instructions ...

I’m working on a Java Spring Boot micro-services application and need a seasoned hand from Pune to straighten out a few points and help me close some production Jira tickets. Most of my questions revolve around how the services talk to each other—specifically, how data moves between them in both synchronous calls (REST, gRPC or similar) and asynchronous flows (message queues, Kafka, etc.). I’d like you to walk me through the current interaction patterns, point out bottlenecks or anti-patterns, and suggest improvements. At the same time, I’ll share a small batch of Jira issues that are already reproduced in our lower environment. They typically involve cross-service data consistency or timing problems. Your role is to propose—and, if feasible within t...

I am looking to hire an experienced Java developer to build and extend a backend application using Java 21 and Spring Boot. The project involves developing REST APIs, implementing Spring Batch jobs, and using Java lambda/functional programming where appropriate. The application will be deployed on AWS, so hands-on experience with AWS services (EC2, RDS, S3, IAM, or Lambda) is required. Strong knowledge of Spring Security, JPA/Hibernate, and relational databases (PostgreSQL preferred) is expected. The developer must follow clean code practices, proper package structure, and standard Spring Boot conventions. Automated testing using JUnit, Mockito, and API testing tools should be part of the delivery. Clear communication, incremental delivery, and well-documented code are...

...The entire purpose of the app is to give users curated daily health and hygiene tips in a clean, lightweight interface—think quick inspiration rather than a complex tracker. Because I purposely don’t want push notifications, the advice should appear only when the user opens the app. Here’s what the finished job looks like: • Signed release AAB (or APK if you prefer) compiled in either Kotlin or Java, ready for upload • A simple, modern UI that lists one tip per day and lets users swipe back through previous tips • Complete Play Console setup: screenshots, short description, long description, privacy policy link and proper category selection so the app is approved on first review • Transfer of source code and keystore once the listing ...

...without being kicked out to a browser. I am open to the payment gateway you feel most comfortable with—as long as it works smoothly for Indonesian users and passes Google Play requirements. Please keep the codebase clean and documented so I can extend the app later with other features. Deliverables I expect from you: • Production-ready APK and Play Store-compliant bundle • Full source code (Java, Kotlin, or Flutter—your choice, but stick to one) • Integrated, fully tested payment flow running in both sandbox and live modes • Clear hand-over documentation: build steps, environment variables, and how to switch keys If you’ve built similar Android payment apps before, share a link or short demo so I can see your approach. Let me know ...

I’m midway through a Java-based project and need an experienced developer to steer me in the right direction. My main goal is to deepen my understanding of core and advanced Java concepts, refine the structure of my existing code, and learn best practices that I can carry into future work. Here’s the kind of support I’m hoping for: • Short, focused live sessions (voice or video) where we screen-share, walk through my current code, and tackle the specific problems I’m facing. • Clear explanations backed by concise code snippets so I can see how to implement each suggestion immediately. • Follow-up notes or quick reviews of any revised sections I send your way, to confirm I’m applying the guidance correctly. No lengthy document...
