Project Overview(Backend Microservices System (SPRING FRAMEWORK ONLY)) We are developing a large-scale, enterprise-level digital commerce platform on a Java-based microservices architecture (Spring Ecosystem). The development phase is "LARGELY COMPLETED". We are not looking for a builder to start from scratch, but rather a "finisher"—a skilled Backend Engineer to take ownership of the existing codebase. The primary goal is to validate current integrations, stabilize the logic, and ensure the system is production-ready through rigorous testing. WE WILL PROVIDE TESTING HELP FROM OUR SIDE TOO. 2. Current Project Status & Scope The following microservices have been developed. Your role is to ensure these services co...

I need a series of concise tutorial videos that clearly demonstrate my code in action. The goal is to help brand-new customers understand how each feature works, so the recordings should feel welcoming and straightforward even for someone seeing the product for the first time. Each video will focus on a single feature walkthrough—from opening the project, stepping through the relevant functions, to showing the finished result—highlighting practical use rather than deep theory. Good screen-capture quality, a clean voice-over, and on-screen callouts where helpful will make the explanations land. Please deliver the finished MP4s plus any editable source files you use (e.g., Premiere, Final Cut, Camtasia, or similar). If you include short intro/outro bump...

I’m moving into Phase 2 of the Keezy calling app and now need a polished Windows installer that users can download straight from our website, receive by email, or find on the Microsoft Store. The core application is already built and stable; what’s missing is a clean, professional package. Scope of work • Package the existing Windows build into an installable format (EXE, MSI or MSIX—whichever best fits Store submission requirements). • Ensure the installer sets up all required dependencies, registers file associations if any, and places shortcuts correctly. • Produce one signed build ready for direct download/email distribution and a Store-compliant package that passes Microsoft Partner Center validation. • English-only interface is fine; mult...

...and décor. Here is what I will provide: the 2D plans, exterior elevations, a finishes schedule and inspiration images that clarify style and colour palette. If you need anything else (e.g., ceiling heights, fixture specs) let me know early so I can supply it. What I need back: • A navigable walkthrough (WebGL, exe, or cloud-hosted link) that runs smoothly on an average laptop for live client demos. • A short cinematic fly-through video (1080p) for backup and marketing use. • Source files of the 3D model (SketchUp, Revit, 3ds Max, or similar—use whichever pipeline you are most comfortable with, as long as the textures stay linked). Acceptance criteria • Spatial accuracy matches the provided drawings ±2 cm. • All fixed fu...

...birth, ID numbers, etc.) has to be filled. Basic validation—presence checks and simple format rules—is sufficient; anything more can stay out of scope for now. • The end result should feel native: once the API call succeeds, the user sees the customer screen with every mapped field in place and can immediately continue the usual onboarding process. Deliverables I expect: 1. Integration code (Java / PL-SQL wrapper or preferred Flexcube extension) committed to a Git repository. 2. Mapping document that shows each JSON field and its corresponding Flexcube column. 3. Simple test script or Postman collection proving the end-to-end flow. 4. Brief deployment notes so our ops team can move it from UAT to production without a hitch. If you’ve wo...

Scope • Diagnose and fix existing errors in the REST layer, services, or related model classes. • Add clean, well-documented GET and POST endpoints so devices can reliably push data and consumers can pull it back. • Ensure responses follow our current JSON schema and return the correct HTTP status codes. • Provide concise unit or integration tests that demonstrate each fix or new endpoint working end-to-end. Acceptance criteria A pu...

I’m rolling out a new feature that touches both ends of our stack. On the backend we run Java 21 with Spring Boot micro-services, alongside a small Node.js/Python layer that exchanges events through Kafka. The frontend is split between an older Angular module and a newer React interface. The job is to design and code the complete feature, wiring it cleanly into every affected service and UI surface. You will: • Extend (or create) the relevant Spring Boot endpoints, making sure they publish and consume the right Kafka topics. • Update the Angular dashboard and the React SPA so the user experience is seamless across both frameworks. • Keep code idiomatic, unit-tested, and pushed to our Git repo via pull requests. Acceptance criteria • A...

...Frequency Drive is running on existing code that now throws unexpected errors during operation. I need an experienced developer to dive into the current project, isolate the bugs, and deliver a clean, reliable version of the program that restores full functionality. You will have remote access to the controller and the full source package as soon as we agree on an NDA. Once inside, I expect you to: • trace and document the root cause of the faults, • correct the offending sections of code, and • verify the fix on-site or through simulated load tests so the drive performs to spec across all speed ranges. The job is complete when the code compiles without warnings, the VFD responds accurately to every command sequence, and I recei...

I’m creating an online store for cosmetic products and want the codebase to feel as professional as anything you would ship to production. The backend must be written in Java with Spring Boot, exposed through well-structured REST endpoints, and persist data in MySQL. On the client side I only need a clean, responsive interface built with plain HTML, CSS and vanilla JavaScript—no heavy frameworks—so that the focus stays on clear architecture rather than flashy UI libraries. Core features I expect: • Role-based authentication for Admin and Customer accounts, supporting registration, login and logout with secure password storage. • Admin dashboards to add, edit and retire products, plus view basic order information. • Customer-facing catalogue with...

I’m expanding several engineering teams for top-tier MNCs and rapidly scaling tech start-ups and need skilled people who can jump in right away. The first seats I must fill are: • Software Developers who are fluent in React, Node, and/or Java. If you can architect front-end components in React, build robust APIs with Node, or craft enterprise-grade services in Java, you’re already on my shortlist. • Data Analysts & Data Engineers able to turn raw data into clean, actionable insights. Solid SQL skills are essential, and if you have experience with Python, Spark, or comparable tooling, that will be an added advantage. • UI/UX Designers who can translate complex product ideas into polished, user-centric interfaces, balancing aesthetics with ac...

...and grades/performance, all pulled from our current REST endpoints. Data caching, photo upload, and simple edit forms already exist in Java and must be replicated in Dart without losing validation rules. 3. School Contacts & Calendar – For this first sprint I only need the staff directory portion live. Search, role filtering, click-to-call, and email links should work out of the box. The calendar view may stay read-only for now; it simply has to render the same event feed we already expose in JSON. You have to use same Android source, API codes (Extract), and the original UI assets. Keep the file and folder structure Flutter-standard, comment the code clearly, and ensure it builds for both Android and iOS (latest stable channel). Let’s target c...

This project centres on building a native Android application from the ground up. The exact domain is still open—whether the final product supports e-commerce, social networking, education, or another category will be decided once we refine the concept together. Key functionality is equally flexible. Depending on the agreed use-case, the build may include fundamentals such as messaging, user profiles, a news feed, or any other feature set that fits the solution. Code should be written in Kotlin or modern Java within Android Studio, follow current Material Design guidelines, and be structured for easy maintenance and future feature expansion. Deliverables • Fully-tested APK and complete source code • Brief technical documentat...
