Redis Jobs

Trabajo sobre un servidor cPanel con Ea-nginx corriendo en AlmaLinux. El problema que quiero resolver: cada día el caché de Nginx se vacía; las reglas están configuradas para un TTL de hasta un año, pero no sobreviven más allá de un día. Antes ya se hicieron dos tipos de cambios que no pueden perderse: • ajustes finos en las reglas de caché • optimizaciones de rendimiento generales El servidor cuenta con Redis. Necesito que revises la configuración actual, identifiques por qué el espacio de caché se borra y apliques los cambios necesarios para que sea completamente persistente,preservando las las reglas personalizadas existentes. Entrego acceso SSH y WHM; espero como entrega final un brev...

The goal is to build a lightweight yet reliable tool that measures and compares the delivery latency of live football data coming from four feeds: betradar, runningball, genius, and IMG. I need a unified service that pings those endpoints in real-time, time-stamps every update, and highlights any delay between them. Core workflow • Open a WebSocket or polling connection to each feed. • Record the exact arrival time of every odds or event message (sub-second precision). • Store raw packets and timing metadata in a fast store (Redis, InfluxDB, or similar—open to your suggestion). • Present latency gaps on a simple dashboard: table view, sortable columns, and a live chart that auto-refreshes. • Trigger an alert (Slack or email) whenever any...

Title: Expert DevOps Needed: Ultra-Fast Laravel Reverse Proxy Setup for 50k Concurrent Users (From Scratch) Description: I am looking for an elite Server Administrator / DevOps Engineer to completely wipe my current server infrastructure and build a highly secure, lightning-fast architecture from ZERO. My project is a high-traffic Laravel-based crypto/investment platform. There should be absolutely zero delay, no lag, and no loading issues. The setup MUST handle 50,000 active concurrent users smoothly. What I have: * Main Server: 64GB RAM Dedicated Server (Offshore/Bulletproof). * Frontend VPS: To be used as a Reverse Proxy to hide the Main Server IP. * Domain: Registered on Njalla (Cloudflare DNS).

I already have a complete full-stack crypto-exchange codebase ( 16 + React 19 on the front end, Node.js/Express with Sequelize on the back end, MySQL as the primary datastore, Redis for caching/queues, all managed in a pnpm monorepo). What I need now is a smooth, secure production deployment on my Hostinger VPS. Here’s what has to happen: • Set up the VPS from scratch: install and configure MySQL and Redis. • Obtain and install a Let’s Encrypt SSL certificate, then put Nginx in front as a reverse proxy. • Wire my domain to the VPS and make sure it resolves over HTTPS. • Configure all environment variables in the .env files; I still have a few API keys and some domain/VPS details to share with you once we get started. • Use PM2 to keep two serv...

Quero colocar em produção um MVP de plataforma de atendimento via WhatsApp que use Z-API para conexão e OpenAI para inteligência conversacional. A ideia é simples: o bot deve responder automaticamente às primeiras mensagens do cliente e, quando necessário, encaminhar a conversa para um atendente humano sem perder o histórico. O que preciso que você implemente: • Integração completa com Z-API para gerir envios, recebimentos e webhooks. • Módulo em OpenAI (chat-completion) capaz de entender FAQ e gerar respostas coerentes em português. • Lógica de triagem que, ao detectar pedidos específicos ou palavras-chave configuráveis, transfira o chat para um painel de agente...

We are building a sophisticated, low-latency traffic management platform designed to perform real-time visitor segmentation. Our goal is to develop a "Smart Proxy" that distinguishes between automated crawlers (Ad Networks, Spy Tools, Headless Browsers) and genuine human users to dynamically serve content without traditional 301/302 redirects. The Challenge: You aren't just building a web app; you are building the "Brain" that manages thousands of requests per second. You must solve for sub-100ms response times while performing deep-packet and browser-level analysis to stay one step ahead of the most advanced bot-detection algorithms on the planet. Key Responsibilities & Scope: • The Filtering Engine: Build a multi-layered analysis pipeline (IP Intelligenc...
