...summarised once a week and shown back as an attractive chart. The single most important feature is this visual graphic of the words, so please give special attention to that part of the UX. How it should work • While the keyboard is in use, capture each word in the background and tag it with an emotion label (happy, sad, angry, etc.). • At the end of every 7-day cycle, compile a weekly recap and keep the previous weeks available for scrolling back. • Inside a settings or dashboard screen, display the recap in an interactive bar, pie, or line chart—whichever communicates the distribution of emotions best. Technical notes – Native Android code in Kotlin or Java is fine; please follow mode...

...cloud-based components, and I want these connections built with clean, well-tested code. Your job is to design and implement REST APIs in both Java and Python, wire them up to PostgreSQL for transactional storage, and index searchable content into OpenSearch so that each event is instantly discoverable. The core of the work is twofold. First, map and integrate the existing internal services with the cloud resources I will provide (IAM-secured endpoints, message queues, and object storage). Second, expose that integrated functionality through RESTful endpoints that follow standard HTTP semantics, are documented with OpenAPI/Swagger, and include unit and integration tests. When the work is complete I expect: ...

...food-delivery concept to life and need an experienced Android developer to build a complete mobile app from the ground up. The core idea is straightforward: customers browse local restaurant menus, place an order, pay in-app, and track their courier in real time until the meal arrives at their door. Here’s what I have in mind: • A clean, intuitive customer interface for account sign-up/login, location detection, menu browsing with search & filters, customisable orders, cart management, secure checkout, and live order status. • A lightweight courier module that receives delivery requests, turn-by-turn navigation, and status updates (“accepted”, “picked up”, “delivered”). • ...

...Python code that contacts my broker’s through enc module / API and streams live stock prices exclusively for NSE symbols. Because the source is wrapped in an encrypted file i cannot edit or add macro to it. Your task is to open up that protection, surface the underlying Python/VBA, and leave me with a readable, editable solution that still performs exactly as it does now—continuous NSE variables updates into the same Excel front-end. The finished file must stay in .xlsm format so all my existing dashboards keep functioning. Deliverables • Unlocked .xlsm containing clean, well-commented Python (xlwings / win32com) or VBA modules • A brief note explaining any dependencies, API keys, or library versions required to keep ...

...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 for power users who may tweak train numbers, class, dates, or passenger lists on the fly. I&rsquo...

I’d like a self-contained, Maven-driven demo that shows how a Wildfly 20 Java servlet can talk to three separate mobile authenticators—Microsoft Authenticator, Google Authenticator and Duo Authenticator—and report back the outcome of each challenge. Scope • Focus exclusively on “second-factor” calls: how the servlet initiates a push / TOTP / Duo prompt (the “sending signal” part) and how it parses the success, timeout or failure response that comes back (“receiving results”). • No UI polish is necessary; a simple JSP or REST endpoint that prints JSON or plain text is fine as long as the code flow is clear. • Keep the sample lean but complete: working source, config files, ...

DVBT-2 QAM Simulink Model Building a full-path DVB-T2 physical-layer simulation in MATLAB / Simulink and need a clean, well-documented model that demonstrates Adaptive Modulation and Coding using Quadrature Amplitude Modulation. The core emphasis is on the modulation scheme itself rather than error-control blocks or post-detection processing, so the model should let me vary constellation orders (e.g., 16-QAM, 64-QAM, 256-QAM) and observe the impact on throughput and BER under different channel conditions.

...need a lightweight Windows desktop application that keeps local Microsoft SQL Server databases in step with a master copy stored in Dropbox. Each time we export a fresh SQL dump (or .bak) into a dedicated Dropbox folder, the app should: • Detect the newest file, download it, and restore/overwrite the user’s local database. • Record and display the exact date-and-time of the last successful sync on the main screen. User management is simple but essential. New users create an account with email and password; those credentials must be validated against a small admin-managed list stored centrally (a table in the same master DB or a lightweight cloud file is fine). If I mark an account as deleted in the admin panel...
