Todo funciona bien durante los primeros días, pero pasadas unas 72 – 96 horas aparece un mensaje de error y la aplicación deja de responder. El fallo no siempre es el mismo; simplemente “no funciona” y me impide seguir registrando pedidos. Lo que necesito es soporte de mantenimiento correctivo y, si es posible, preventivo, EN AMBOS CASOS DE MANERA DIARIA DE SER EL CASO SUJETO A DEMANDA: • Diagnóstico inmediato cuando aparezca el mensaje de error. • Corrección definitiva para que el fallo no reaparezca. • Breve informe técnico con la causa raíz y los pasos aplicados.

Subject: Inquiry: Building a scalable, multi-industry compliance engine Dear Coders I am looking for a lead developer to help me build the backend engine for a professional ecosystem platform. I already have the complete UI/UX designed, but I need a serious engineering brain to build the logic beneath it. At its core, it is a compliance tracker that monitors professional and routine documents. I will give examples of teachers, to put things into perspective. The system will flag documents as up-to-date, expiring, or missing; -The document can be career protecting registration documents like CEU credits, health certificates, academic certificates, police checks, immigration wok permits etc, -Routine weekly records like Head of department Reports, Incident reports, Trip Reports, Tutor-Tut...
I have a small, well-scoped task centred on improving the existing backend logic of my application. The codebase is stable, but some routines are slower and more convoluted than they need to be, which is starting to bottleneck new feature development. What I need from you is a clean refactor of the relevant modules so they run more efficiently, are easier to read, and remain fully compatible with the rest of the system. I will provide the current repository, a short architectural walkthrough, and unit tests that must keep passing after your changes. Acceptance criteria: • Functionality and API surface remain unchanged. • All existing automated tests pass; new tests cover refactored paths. • Measurable improvement in execution time for the target routines (I&rsquo...

Objective: Enable direct Usenet streaming into Stremio with minimal storage usage and a stable lightweight setup. Scope of Work: - Provision or configure a Ubuntu 22.04 or 24.04 ARM instance ( within Always Free limits) - Install Docker and Docker Compose - Deploy a working Docker stack including: - NZBDAV (WebDAV streaming backend) on port 3000 - UsenetStreamer configured in NZBDAV mode on port 7000 - Ensure proper container networking using internal service names (depends_on and NZBDAV_BASE_URL: http://nzbdav:3000) - Co...
I need to formalise a complete troubleshooting process for oil-and-gas service for different equipments . The job has two core outputs: • A structured, queryable database that captures every data point needed to diagnose and prevent failures. I will supply raw spreadsheets and field notes; you will design the schema, normalise the data, migrate what I give you, and leave me with an easy way to expand it later (MySQL or PostgreSQL preferred, but I am open to your recommendation). • A detailed Fault Tree Analysis that maps all credible failure modes for these equipments and links directly back to the records in the database. The FTA should be delivered both as an editable file from a recognised reliability tool (e.g., ReliaSoft, FaultTree+, or equivalent) and as a PDF for qui...
I need assistance to populate an SQL Server database from another table based on specific conditions. Requirements: - Source data from an existing table - Populate mixed data types (text, numeric, etc.) - Maintain data integrity and accuracy Ideal Skills and Experience: - Proficiency in SQL Server - Experience with data manipulation and table management - Attention to detail and data accuracy - Familiarity with mixed data types in SQL Timeline: 1 week
I have an in-house C++ data engine that talks to a MySQL front end. Under normal use it works, but once we start running real-world queries it can crash outright and, when it stays up, occasionally returns missing rows or pulls the wrong records altogether. These errors only appear while queries are executing; startup and idle periods are trouble-free. Your task is to track down the causes of the query-time crashes, eliminate them, and tighten the code so the engine no longer drops or misreports data. I expect clean, well-commented fixes, unit or integration tests that prove stability against typical and edge-case queries, and a brief summary of what was wrong and how you corrected it. C++, MySQL, and solid debugging tools (gdb, Valgrind, sanitizers, etc.) will be essential. Once t...

I have two virtual private servers that run several MySQL databases, yet no one can reach them externally—not even a basic telnet on port 3306. I need somebody to jump in, locate the bottleneck, and open things up so remote clients can connect with full administrative privileges. You will get SSH access to both VPS instances plus the root credentials for MySQL. I’m unsure whether any firewall (iptables/ufw/cloud panel) is blocking the port, or if the issue sits in ’s bind-address or a host-based restriction. Whatever the culprit, I just want it resolved quickly and cleanly. Acceptance criteria: • From any trusted external IP we agree on, a telnet to each server on 3306 succeeds and the MySQL client can log in using the admin user I provide. • Existing data...
I run Delinea Secret Server Cloud (full Secrets Suite) and need someone who already knows its REST API inside out to bring two database platforms—MySQL and MongoDB—under management. I want the procedure to remain manual, yet fully documented and repeatable, so the next engineer on my team can follow it step-by-step without guessing. Scope • Use native Secret Server Cloud / SecretSuite API calls to create appropriate folders, secrets, and roles. • Onboard the MySQL and MongoDB service accounts, set rotation schedules, and confirm successful check-in / check-out. • Expose vault health and rotation events to our monitoring stack (Prometheus + Alertmanager) through the platform’s event hooks or syslog/HTTP endpoints. No extra plugins needed. Deliverable...
I need the latest stable build of OSPOS fully installed and running on my existing shared-hosting account. The server already meets the standard requirements for the system—PHP and MySQL are both available and properly configured—so the task is largely about uploading the codebase, creating the database, and ensuring everything points to the correct environment variables. I’m not looking for any custom plugins, theme tweaks, or added features right now; a clean, out-of-the-box deployment is perfect. Once it is online, I’d like the default admin credentials changed, basic security settings verified, and a quick note of any host-specific tweaks you had to make so I can repeat the process later if needed. Deliverables • Live, accessible OSPOS instance on my sh...

I need a JasperReports specialist who can craft a production-ready detailed report. The layout must pull multi-table information using complex SQL—think layered joins, nested sub-queries, and on-the-fly aggregations—while still running quickly on a live data set. The report itself goes beyond a simple summary: every record should print in full, grouped where appropriate, with running totals and sub-totals calculated through well-designed $V{} variables. Several runtime parameters ($P{}) will drive filtering (date range, status, and a couple of optional flags), so you need to be comfortable moving data among $P{}, $F{}, and $V{} without breaking the formatting. Deliverables • Fully tested .jrxml and compiled .jasper files • All SQL queries used, clearly comme...
Looking for Senior Backend Engineer — Data Pipeline & Scalable Systems (Node.js + PostgreSQL)
My in-house development team built a fully functional ERP to manage our large-scale manufacturing and export operations, yet day-to-day use feels sluggish. Endpoints take too long to resolve, database queries lag, and occasional hiccups interrupt our workflow. I’m looking for an experienced developer who can dive into the existing codebase, pinpoint the bottlenecks, and leave me with a noticeably faster, error-free system—all within the next month. The core modules (inventory, B2B/B2C sales, manufacturing tracking, reporting, and everything in between) already work; the goal is to make them run smoothly. You’ll need to review the current architecture, container resource allocation, database design, and API interactions, then implement optimizations without disrupting liv...
I need a specialist to dive into my existing ECAAM environment and complete a full system configuration. The focus is on three core components: • Database – configure schemas, connections, and any tuning that will keep queries fast and reliable. • Network settings – set the correct ports, security rules, and routing so every ECAAM service communicates smoothly inside our LAN and from remote locations. • Software modules – verify each installed module, adjust its settings, and make sure dependencies are resolved. The installation itself is already in place; what I am missing is a clean, production-ready configuration that I can rely on without constant patch-ups. You are free to use the tools you’re most comfortable with—command-line, GUI u...
