    I need a lightweight proof-of-concept that demonstrates an end-to-end OAuth 2.0 flow against a real healthcare EMR, then uses the granted token to call the FHIR Patient endpoint. The aim is simple: confirm that system-to-system (backend) credentials can be exchanged for an access token and that—with that token—I can reliably pull a single Patient resource when I supply either the patient’s MRN or their ID. Here is how I picture the work: • Implement the OAuth 2.0 client using the EMR vendor’s documented authorization-code or client-credentials flow (whichever the API allows for backend access). • Once authenticated, call the FHIR /Patient search endpoint twice—first filtering by identifier type “MRN”, then by the native “ID&rdqu...

    I need a reliable hand to log in to my Tally Prime file each day, enter the fresh vouchers I supply, keep the ledgers tidy, and make sure every taxable transaction is ready for GST filing. Your core focus will be GST compliance—checking purchase and sales entries, matching them with tax rates, reconciling the tax ledger, and preparing the data so my monthly returns can be generated without surprises. Because accurate data is the backbone of smooth GST Filing, I’ll forward all invoices, payment proofs, and credit notes to you as they come in. You’ll post them in Tally Prime the same day, flag any mismatches, and keep a short note of issues that need my sign-off. If you spot an easier way to structure the masters or tax configurations, feel free to suggest it; I welcome wo...

    I need a compact, Linux-friendly suite of command-line utilities written in C or C++ that lets me run deep diagnostics on the following components: • RAM Memory • CPU • HDD & SSD (including low-level write/partition and speed tests) • RF-UNIT support where applicable The tools must be completely CLI-driven so they can slot into existing bash automation. For each utility I also need concise professional usage notes—syntax examples, expected output, and any kernel-module or package prerequisites—so a technician can get productive within minutes. Additional scope items: – Benchmark and stress-test options to reveal peak throughput and thermal throttling on RAM and CPU. – Sequential and random read/write tests on block devices, with sm...

    I have an ESP32 DevKit V1 (CP2102) already wired to a PZEM-004T V3, an ADS1115 16-bit ADC, one SCT-013-010 CT sensor, and three DS18B20 waterproof probes. With this hardware I need working firmware and a simple cloud-hosted dashboard that can: • Detect and log the compressor state (ON/OFF). • Detect, log, and quantify both the indoor fan status(ON/OFF) as well as fan current or speed. • Read room, inlet, and outlet temperatures. • Calculate hourly power consumption (kWh) and total run-time for the compressor and each fan. • Push every reading over Wi-Fi using pure HTTP requests formatted as JSON. On the front end I want a live web dashboard that combines graphs with raw tables so I can flip between trends and exact values. The visuals should update in n...

    I’m building a lightweight Android-only app whose single purpose is to generate random lottery numbers. The interface needs to stay simple and minimalistic—plain backgrounds, clean type, just one or two buttons—so users can open the app and get their numbers instantly. Here’s what matters: • Core feature: a lottery number generator only. No ticket-purchasing or results-checking at this stage. • Platform: native Android, targeting at least Android 8.0. Kotlin or Java is fine. • Look and feel: strictly minimal, using basic Material Components without flashy graphics. • Randomness: please rely on SecureRandom (or an equally strong method) rather than () for genuine unpredictability. • Configurability: all game rules (number range, dra...

    My Facebook Messenger flows are already running smoothly inside ManyChat, but the moment I push a contact over to the data stalls. Tags tied to each lead-magnet download never arrive because the text data inside the payload is not being formatted the way Make expects. I need an expert who has hands-on experience moving text fields between ManyChat and Make (formerly Integromat), setting up custom JSON, and mapping variables so Facebook user details move across reliably. On a live video call I want to: • Walk you through my current scenario, showing where the data stops flowing • Re-configure the webhook / HTTP module so text parameters come through clean and are usable in Make filters • Confirm the tag logic works by sending a test lead from each magnet and watching ...

    I’m enhancing an existing PHP application and now need an experienced developer to wire in several third-party services. The core of the job is to analyse each provider’s endpoint requirements, extend or refactor the current codebase where necessary, and make sure the new integrations run smoothly alongside what is already in production. You will be working with modern PHP (object-oriented, namespaced) on a LAMP stack, so familiarity with RESTful requests, webhooks, JSON handling, and robust error logging is essential. Security is a must—token management, input sanitisation, and graceful failure states all have to be considered from the outset. I’ll give you access to the repository, environment details and any documentation the vendors supply. Your work should pl...
