    I need a developer who is comfortable working directly in Android Studio to make my existing app fully intelligible to screen-reader users. The focus is limited and clear: every form field and button must announce itself correctly when TalkBack (or any compliant screen reader) is active. Here is what I expect: • Add or correct contentDescription attributes, accessibility labels and hints so that controls are spoken in a logical order. • Ensure state changes—errors, success messages, toggles—are conveyed via accessibility events without relying on visual cues alone. • Keep visual layout untouched; all work should sit cleanly in the XML and Kotlin/Java layers. • Provide a short video or emulator capture showing TalkBack reading through...

Typical cycle: – Review crash reports and user feedback from Google Play Console or Firebase, patch bugs, and push an update. – Identify lightweight feature ideas (new mini-levels, reward tweaks, UI polish) and implement them without bloating the APK. You’ll work in Android Studio (Kotlin/Java) and use Git for version control. When an update is ready, you’ll prepare the signed AAB, update the store listing if needed, roll out staged releases, and monitor statistics for any regressions. Deliverables each cycle: 3.

    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 • All API tests p...

    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...

If you have an alternate stack that meets the requirements and speeds development, let’s discuss; the priority is clean code, clear documentation, and future scalability. I’ve allocated a sensible budget and am happy to structure it across milestones (MVP, admin panel, final polish). The full build should be completed within four...

    ...analytics and accept calls that trigger Instagram actions. OAuth2 or JWT security, adjustable rate-limits, and versioning are essential so other teams can plug their apps in without friction. Google scraping engine A headless, proxy-rotating scraper (Puppeteer, Playwright, or a comparable stack) should collect market-trend keywords, volumes, and related SERP snippets on a schedule I can configure. Captcha handling and location targeting are must-haves. Collected data will feed directly into the main database—PostgreSQL or MongoDB—ready for the API and the Instagram module. Instagram marketing module Using the Instagram Graph API or a reliable unofficial library, the system must publish posts, stories, and reels, gather engagement metrics, and run light automatio...

    I need a robust Windows-based application that can grab IRCTC Tatkal tickets faster than manual entry. The core job is full-cycle automated booking: log in, search, select quota and passengers, and confirm payment without human intervention. Two advanced capabilities are non-negotiable. First, the program must solve IRCTC’s captcha in real time—either through a reliable OCR/AI routine or an external service like 2Captcha, Anti-Captcha, or a comparable API you prefer, as long as the response time stays under a couple of seconds. Second, the tool should let me manage and run multiple IRCTC credentials side by side so several bookings can fire simultaneously without sessions colliding. Speed matters more than a pretty interface, yet the UI should be clear enough fo...

    ...Inventory Monitoring: Monitor product status in real-time and trigger order placement the exact moment it changes to "Available for sale." C. Bypassing & Anti-Risk Control Certificate Injection: Provide a solution to bypass certificate validation in specific environments (such as Rooted/Jailbroken devices or emulators). Risk Control Bypass: Provide reserved interfaces or integrate third-party captcha-solving platforms to handle risk control measures triggered during order placement, such as image captchas or sliders. 4. Deliverables Requirements Complete Source Code: Must include the core reverse engineering logic and the recreated encryption algorithm code. Environment Setup Guide: Instructions on how to configure the packet capture environment (e.g., using C...
