JSON Jobs

I have a MySQL database that stores stock-market-related records. I need a lightweight script or micro-service that will: • Query the required rows on a schedule or on demand, • Convert the result set into a clean JSON payload, and • Push that payload to a remote endpoint via a standard webhook (HTTP POST with a bearer token). The table structure is already in place; I will explain the field names you should map. The JSON shape has to match a small schema I’ll share, but it is simple key-value pairs—nothing nested beyond one level. Code can be in Python, Node.js, or PHP as long as it runs reliably on a Linux server. Use parameterised queries (or an ORM if you prefer) so there is zero risk of SQL injection, and make sure any credentials sit in an external c...

The task is to build a small-scale robo-click solution that routes every request through genuine US residential proxies. I will supply the list of content-based sites (mostly news and blog pages) and the exact URLs that need to be visited. Each hit must mimic a real user—clean headers, realistic delays, no datacenter footprints—so that our analytics platform records the visit as organic. The sole objective is to generate accurate engagement data for an existing business, not to boost ad revenue or manipulate rankings. Core workflow • Spin up a fresh residential IP for every session (or at minimum every N clicks, configurable). • Open the target page, wait for it to load fully, follow the designated link(s) in sequence, then exit cleanly. • Log timestamp, p...

I am looking for a developer to help build a REST API using PHP that interacts with a MySQL database containing information about an academic conference (presentations, authors, and presentation types). The API should be structured and follow good software architecture practices. It will include endpoints to retrieve and manage data such as authors, presentations, and presentation types. The API should return responses in JSON format, support HTTP methods (GET, POST, PATCH, PUT, DELETE) where appropriate, and follow RESTful design principles. Key requirements include: PHP-based REST API (no frameworks) Integration with an existing MySQL database Clean, well-structured code Input validation and secure database queries Pagination support for large datasets Clear API endpoints for aut...

Project Overview I am building an AI astrology chatbot that gives readings based on a user’s natal chart, solar return chart, and lunar return chart. Right now the chatbot depends on users manually going to Astro-Seek, generating chart exports, and pasting those exports into the chat. I want to replace that process with an automated backend calculation engine that generates the chart data directly and passes it into my OpenAI chatbot. This project is not a full astrology app with a GUI. The chatbot is the user-facing interface. What I need built is the chart calculation layer that collects the required birth and return information, calculates the charts accurately, and outputs the chart data in a format my AI system can use. Core Workflow When a user starts the chatbot, the syst...

I am putting together a REST-style API built with PHP and a MySQL database. Its first job is to return user information quickly and in clean JSON, so the user endpoints should focus on efficient, well-indexed SELECT queries and clear response structures. Alongside those read-only calls, I also need a second group of endpoints for product details that can: • return existing records (GET) • add or modify items (POST / PUT) • remove items (DELETE) You are free to work with native PHP, Slim, Lumen, or a full Laravel setup—whichever will let you keep the codebase modular and easy to extend. Just keep the dependencies light and document any third-party packages you bring in. My acceptance check is simple: spin up the project, import the sample SQL I’ll provide,...

I’m looking for a developer who can take my nearly-finished back end and turn it into a polished, modern-and-clean web experience (desktop first). The heavy lifting on data is done: a structured JSON store already matches every major mortgage servicer to the exact documents, phone numbers, and process quirks a borrower needs. I can also share a working Claude project that demonstrates the logic flow, so you’ll start with clear reference material rather than a blank page. What I still need is the front-end and finishing glue: • Mortgage-detail form that validates basic loan data on the fly • Instant on-screen result that tells the user whether they can cancel PMI right now, or why not • A short guided assessment for edge cases, walking the borrower throug...

I already have a fully-built Node.js project (Apostrophe 3 CMS, v 4.8.0) zipped and ready to go. All I need is a smooth deployment to my Hostinger Business Node.js plan so the site becomes publicly accessible on my domain, no code changes, no feature tweaks. Key context • Node version on the server is 22. • Auto-deploy won’t work with ApostropheCMS, so it must be set up as a custom Node.js app. • I do not have SSH enabled on the account. Instead, I can upload through Hostinger’s File Manager and am looking for an alternative workflow that accomplishes the same npm install → npm run build → npm run prod sequence. The archive you’ll receive already contains , package files, all modules, views, public assets, scripts and ; node_modules is i...

2️⃣ Browser Automation & UI Integration Developer We are looking for a developer to help connect browser automation with an existing system UI. The system has already been built by another developer, so the work mainly involves reviewing existing code and connecting components rather than building everything from scratch. Tasks may include reviewing Playwright-based browser automation scripts, making small modifications if needed, and connecting them with the existing system UI or automation flow. Some small adjustments to Chrome Extension scripts may also be add grok The system structure is documented in Notion. Work should be performed by comparing the Notion documentation with the actual implementation step-by-step to identify missing connections or adjustments. JSON files and c...

I’m working on a project with the AVR-IoT Cellular Mini (Sequans Monarch 2 modem), where I modified the Arduino-based firmware myself to periodically transmit GPS latitude and longitude data to my backend (BE) over HTTPS. The objective is to send GPS data (latitude, longitude, and timestamp) to a REST API endpoint at a defined interval and confirm that the data is successfully received and visible on the backend. At the moment, I’m blocked by a TLS issue while attempting to configure the CA certificate for HTTPS. When I try to add the root CA certificate (ISRG Root X1 – Let’s Encrypt) to the device/modem, I get an error that says: “CA certificate input too long” Because of this issue: • The TLS handshake fails. • The HTTPS request does no...

Vision This is an education technology platform focused on improving MCAT CARS performance through efficient content delivery and intelligent processing. This project is the first step toward a larger system. The goal is to build a simple, clean, single‑page prototype that accepts a URL, sends it to a backend endpoint, processes the content, and displays the extracted text on the same page. This prototype will be used to validate core functionality before expanding into a full product. Project Overview Build a minimal, production‑ready single‑page web application with one input field for a URL and a content display area that updates dynamically based on backend output. The backend will fetch the URL, extract readable text, and return it as JSON. The frontend will display the returned co...

I need a clean, well-documented Node.js solution that fetches JSON data from a specified API endpoint and turns it into a professionally formatted PDF made up exclusively of tables. The flow is straightforward: call the API, parse the JSON payload, map the fields to table columns, then render each table so it paginates gracefully and, when necessary, repeats headers across pages. Key points • Source data arrives solely from an API in JSON format—no manual entry or secondary feeds. • The PDF contains tables only; no images or free-form text blocks beyond table headers or footers you may add for clarity. • Any solid, maintained library is fine—pdfkit, Puppeteer, jsPDF, or a comparable Node.js toolset—as long as it supports custom styling (borders, alte...
