De 42,620 opiniones, los clientes califican nuestro DevOps Experts 4.9 de un total de 5 estrellas.I have a handful of production-level websites built with running on a Node.js back end, each exposing AI-driven endpoints and features. Before traffic scales any further, I want every possible door that an attacker might exploit closed—whether that means fixing insecure code patterns, tightening DevOps settings, or putting guardrails in front of the AI models themselves. Here’s what I need from you: • A thorough security audit that covers code, dependencies, build pipeline, server configuration, AI endpoints, and any third-party integrations. • Concrete remediation: update or patch the code, configure headers, implement rate-limiting, add encryption where missing, and harden authentication/authorization flows. • A clear report that documents every vulnerabi...
I’ve just spun up a completely fresh Debian VPS and need a single‐run script that leaves it production-ready for a backend. Your script should: • Update and harden the server (apt update/upgrade, basic firewall, fail2ban or similar). • Install and configure the latest stable Postgres along with PgBouncer, create a default database/user, and make sure they start on boot. • Register the VPS hostname with my Namecheap domain, then request and renew a free Let’s Encrypt SSL certificate. • When everything is live, echo one concise line that I can paste straight into my .env file, e.g. DATABASE_URL= Please keep the script readable (Bash or Ansible preferred, but open to alternatives) and include brief comments so I can tweak settings later. A quick R...

We operate a production mobile app with a Laravel REST API and MongoDB backend. An internal Laravel-based admin dashboard already exists, but the current API monitoring only checks endpoint availability and does not reflect real system or business health. We are looking for an experienced Laravel backend engineer to design and implement a professional health monitoring & incident system, comparable to how large platforms (Meta, Google) monitor real user journeys, not just HTTP status codes. This is not a UI-only task and not a web application project. The system must simulate real mobile API flows (synthetic checks). Proof of Concept / Demo Requirement (Important) Before integration into our production system: The freelancer will build a working demo / proof of concept on their own ...
Our ERC-4337 gas-sponsorship backend is feature-complete at MVP stage; now I want to push it to the edge before we move to mainnet. Your first mission is pure stress: generate concurrent requests from many independent sources and see how the API stack behaves under sustained, spiky loads. Locust is the framework I’d like you to start with, but feel free to extend it or plug in complementary tooling if it uncovers deeper issues. Here’s the landscape you’ll be attacking: • Account-abstraction flow that routes across multiple paymaster providers with automatic fail-over. • Budget enforcement logic that must never overshoot per-dApp or per-wallet caps. • Settlement and reconciliation jobs running against Base, Arbitrum and Optimism testnets. •...

I’m ready to move three exchange-market web and mobile products from concept to live operations and I’m looking for a true technical co-founder here in NYC. One product is already largely built; the other two are sketched out, with one being a genuinely novel play I haven’t seen anywhere else. You would bring full stack development expertise and take ownership of the technical roadmap—from polishing the existing codebase to architecting, deploying, and scaling the remaining apps. I have no experience managing servers, so the DevOps side (cloud hosting, CI/CD, monitoring, security hardening) will be in your hands as well. I’m covering all out-of-pocket costs and will handle fundraising and regulatory work. Until the products generate revenue this is strictly ...
Looking for an engineer to stabilize an existing n8n automation system. Goal is to fix blocking errors and ensure end-to-end execution (script → image → voice → video → upload). No new features or redesign — stabilization only. Docker-based environment.
I am looking for an experienced Python developer to restore and stabilize an existing Python automation environment on a Windows VPS server. All Python scripts already exist and were functional before a recent server migration. After the move, the environment stopped working and the original developer is no longer available. The task is to review the existing scripts briefly and make the complete environment operational again via Windows Remote Desktop Services. The scripts do not need to be rewritten, except for small adjustments that are required to restore functionality or improve reliability after the migration. Technical Scope The work includes restoring and configuring all required components such as the correct Python version or versions, virtual environments, system paths, backgr...

I already have a complete n8n workflow built and running on n8n cloud; now I need it hosted permanently on a local Windows server that I control. Your job is to install n8n on that machine, migrate my existing workflow, and make sure everything runs reliably every time the server reboots. You’ll be working with Windows Server — no cloud or dedicated hosting, just this on-prem setup. Deliverables I expect: • n8n installed and configured as a Windows service (or comparable solution) so it starts automatically • My exported workflow imported and confirmed working end-to-end • Clear notes on any environment variables, ports, or dependencies you touch I can provide remote access (RDP or preferred tool) and the workflow export file as soon as we start. If thi...
I’m looking for a seasoned Cloud & DevOps engineer who can be on-call for two scheduled hours each weekday and walk me through issues live over a screen-share. You will not log in to the servers yourself; instead, you’ll act as a real-time coach while I operate the keyboard. Day-to-day you’ll help me: deploy and tweak Kubernetes workloads on AWS, untangle CI/CD flows built around ArgoCD and GitOps, and sanity-check everything from Prometheus-Grafana dashboards to Splunk logs and CloudZero cost insights. When something breaks—be it a Kafka topic, a DynamoDB table, or our Go microservices—you’ll jump on a video call, see exactly what I see, and advise on the quickest, safest fix. The commitment is strictly part-time (about 10 hours a week), yet r...

I need a production-ready SIAPP container that runs on the Siemens SICAM A8000 platform and acts as an MQTT client. The container must connect to a MQTT broker, read the A8000’s configured digital inputs, analog inputs and status signals, publish those values, and in the opposite direction subscribe to topics carrying status updates and control commands so the payloads can be written straight back into the matching SICAM signals. The work involves building the application on embedded Linux, packaging it as a SIAPP, and verifying it on real demo hardware. Clean logging, reconnect logic, and graceful handling of network interruptions are essential, as this will be deployed in an operational substation environment. SDK: Deliverables • Compiled SIAPP image with all dependencies ...
I run a live Ubuntu VPS that serves my working web application, and I’m tired of logging in every few days just to pull code, patch packages, and restart services. I need a rock-solid, hands-off update routine that keeps both the underlying OS packages and my deployed web apps current without breaking anything or causing downtime. Here’s what I’m after: • Configure unattended-upgrades (or a comparable solution) so system and security patches install automatically and safely. • Set up an update workflow for the existing web applications—whether that’s a Git-based pull with hooks, a CI/CD runner, or a well-crafted shell/Ansible script with cron—so new releases roll out on their own. • Include sensible logging and notification (e-mail ...

My Drupal site needs a single round of professional upkeep focused on two critical areas: applying all current security updates and squashing a handful of persistent bugs. I’m running the latest major version of Drupal core, but several contributed modules and custom code pieces haven’t been patched in a while, and a few error messages have started to appear in the logs. Here’s what I’m looking for: • Audit the site (core, contributed modules, themes, and custom code) for available security releases and apply every relevant patch. • Track down and fix the bugs I’ll share from the watchdog logs and front-end reports, making sure no new warnings appear afterward. • Test everything thoroughly on a staging clone, then deploy to production usi...

I need an end-to-end e-commerce site that sells physical goods under three distinct business models—B2C, B2B, and D2C—while letting me manage multiple warehouse or store locations from one dashboard. Core storefront functions such as catalog browsing, dynamic pricing/discounts, cart, checkout, taxes, invoicing, and real-time stock updates must work seamlessly across every location. Each customer type should see the right catalog, pricing tier, and payment terms the moment they sign in. Order fulfilment has to accommodate both Standard and Express delivery, pulling live rates and automatically routing each order to the nearest stock point. A shipment-tracking view for customers and an internal panel for returns/RMA processing are essential. Social reach is critical: the...
Our Jenkins instance is already up and running and our codebase is split into several microservices. What’s missing is an airtight, fully automated deployment flow. Your sole focus will be deployment automation: from a successful merge to a live, versioned microservice with no manual intervention. You’ll be creating and refining Jenkinsfiles that handle build, test, container image tagging, registry pushes, and the final deploy job. The existing monitoring hooks and general pipeline scaffolding are in place, so you can zero in on the rollout logic and reliable rollback. Deliverables • Production-ready Jenkinsfile (or shared library) for each microservice • Parameterised Jenkins jobs wired to our Git repo • Concise runbook covering deployment steps, rollback...

I have a fresh Devuan Daedalus server ready and need the full Barracuda + Octopus + Aegir stack set up with a standard installation. My priority is to get a clean, stable control panel that can start managing Drupal sites right away. Because I am not yet sure which tweaks are worth applying on Devuan, I’d appreciate your recommendations on PHP-FPM vs. CLI settings, Nginx tuning, MariaDB tweaks and any hardening steps that fit well with Barracuda’s default workflow. If the vanilla install already covers best practices, feel free to keep it minimal—just flag anything I should revisit later. Deliverable • Barracuda/Octopus/Aegir installed on Devuan Daedalus, fully operational • Aegir dashboard reachable via HTTPS with an admin account I can log into • ...
Our Azure DevOps multi-stage pipeline is suddenly failing in the second stage with a dependency error. Everything ran cleanly until 8 September; after a flurry of merges, we tried again on 11 December and the break appeared. The code sits in Azure Repos, and I’ve confirmed in a separate branch that the script itself is fine, so I don’t want to edit that script. What I need is a precise git-level investigation that isolates the commit that introduced the regression and cleanly reverts it so publishing to Azure Data Factory can resume. Deliverables • Identify and revert the offending commit(s) through Azure Repos (pull request ready to merge). • Demonstrate a successful run of both pipeline stages after the fix (link or screenshot). If you’re comfortabl...
