I need an experienced infrastructure engineer to help me move my Fintech application off its current host and onto a server stack that is both noticeably faster and cost-efficient. My priorities are low-latency transaction handling, high uptime, and a predictable monthly bill. I am open to any major cloud vendor—LINUX, AWS, Google Cloud, Azure, or an equally robust alternative—provided the final choice can give me the best mix of performance and price. Here’s what I expect: • A short cost-vs-performance comparison of the leading options, with clear reasoning for the recommended platform. • A detailed migration plan that avoids downtime for end users. • Full execution of the migration, including configuration of security groups, autoscaling, ba...
...and Claims must be pushed to my JetForm instance; I will supply the exact form schema and API credentials. Architecture notes • Multi-tenant: each shop sees only its own data, while I keep an overarching Admin view. • Minimal UI: clean bootstrap-level forms are enough—no design polish required. • Tech stack is up to you as long as it is mainstream, maintainable, and deployable on a typical Linux VPS. Deliverables - Source code in a private Git repo - Simple environment file with JetForm keys and tenant defaults - SQL (or migration scripts) for initial schema - Brief README covering setup, tenancy configuration, and video-size handling Acceptance I’ll consider the job complete once I can: create a tenant, sign in as each role, run the ...
The project is already up and running on my local stack (Linux / macOS, nginx as the web server, MariaDB for data, everything container-friendly). If your on windows u will need wsl to run it like I do. please dont bid if u cant set these up. Functionally it does what it should, but the overall layout is amaateur. You’ll work directly in the existing codebase, tweak or rewrite the HTML templates, CSS (or a pre-processor if you prefer), and any lightweight JS that controls visual behaviour.

My production server in Melbourne, VIC refuses to boot and mount one of its EXT4 volumes that holds critical web-server data. I need an experienced Linux sysadmin who can come onsite ASAP, diagnose the mounting failure, recover the volume without data loss and make it reliably mount at boot again. The box is running a recent Centos-based distro and is still fully accessible via console, but remote work is not an option; physical access is required so you can run low-level tools like fsck, tune2fs, debugfs or alternative recovery utilities. What I expect from you: • Arrive onsite (Brunswick West) at an agreed time. • Troubleshoot and repair the EXT4 mount issue, documenting each command and change. • Verify the integrity of the web-server data once the filesystem is ...
...complete setup, spin up the first server, apply sensible security hardening, and leave me with clear notes on what was done and why. Typical touch-points will include picking the right plan, deploying an instance, setting up user access, SSH / RDP configuration, firewall rules, monitoring basics, and any tweaks you consider best practice for performance and reliability. I’m open to either Windows or Linux images, so your recommendation here will be welcome. The job is primarily about the initial setup, but if I’m impressed with your approach there is scope for ongoing management later. Please tell me about similar Leaseweb (or comparable bare-metal/VPS) environments you have built, how you prefer to document changes, and roughly how long you expect the first round o...
I need a complete, self-hosted email solution for a small business that I’ll be running on a Linux server (Ubuntu or CentOS—whichever you feel is best for the chosen stack). The key objective is to move away from third-party providers and gain full control over our mail, security, and data compliance. The specific mail-transfer agent is still open: Postfix, Exim, Mailcow or another proven alternative can be used, as long as the end result is stable, secure, and straightforward to maintain. What I expect from you: • A production-ready mail server configured with SMTP, IMAP/POP3, spam and virus filtering, DKIM, SPF, DMARC, and valid SSL/TLS certificates. • Simple webmail access and clear instructions so that I can add domains, users, and aliases without t...

I need someone to bring my Oracle 11g server online and make sure it starts cleanly every time my Red Hat Enterprise Linux machine boots. The software is already on the box; what’s missing is a reliable, Standard installation-style configuration that finishes the setup, starts the database, confirms the listener is running, and registers the instance correctly with systemd so it survives reboots. You’ll connect over SSH, verify the existing Oracle home, adjust any kernel parameters or environment variables that were skipped, and walk me through the key commands so I understand how to start and stop the service myself. A simple set of notes or a shell script showing the steps you performed is all I need as a final hand-off.
I have a geospatial platform running on a Linux server with PostgreSQL, PostGIS, GeoServer and MapStore. MapStore already includes MapFish Print as the printing engine.

I’m running a self-hosted MeshCentral server on Ubuntu 24 Linux and I need two equally important improvements added to its web interface. 1) Per-user concurrent-session cap From the UI I want to be able to enter a number that represents the maximum simultaneous device connections or remote sessions a given user can open. Once that threshold is reached, additional connection attempts must be blocked until an existing session ends. The setting must work on a per-user basis without impacting other users or global server limits. 2) Account expiry date control I also need a date picker in the user–edit screen that lets me set an explicit expiry date for an account. When that day arrives the account should become disabled automatically, with no manual cleanup require...

I’m putting together a small ARR stack in Docker and need an expert to wire everything so that every outbound request from Prowler and Radar is forced through a Gluetun VPN container. My host is already running Docker on Linux; what I’m missing is a clean, reproducible Compose (or Swarm) setup that: • Spins up Gluetun first, using my WireGuard credentials and built-in kill-switch. • Launches Prowler and Radar as separate services but attaches them to the Gluetun network so they inherit its VPN tunnel for all traffic. • Exposes only the essential web UI ports on the host while keeping search, tracker and metadata queries safely behind the tunnel. • Survives restarts with proper health-checks and dependencies so nothing leaks when the VPN drops...
I have a small Java Swing application where several JCheckBox components refuse to stay checked when clicked. No exceptions are thrown; they simply pop back to an unchecked state immediately.

I need a reliable way to confirm whether a given high-net-worth individual is associated with my freemasonry verification service. For every millionaire in the list I supply—or that you source—you will provide both a verifiable street or registered business address and an official email address. The end goal is to feed those two data points into a DNS-based lookup flow similar to: Linux / Unix: `dig txt ` Windows: `nslookup -q=txt ` Because I will be running checks from machines on both platforms, the script you deliver must execute cleanly under Bash and PowerShell without any manual tweaks. An auto-detect of the OS with the right call to `dig` or `nslookup` is ideal. Deliverables: • A CSV or SQLite dataset

What I need now is for you to unzip the project, configure it to run in a headless setup—Browserless, Puppeteer, Playwright, or any similarly fast alternative—and prove that it consistently books the target slots faster than a normal browser session. Here is the flow I expect: • Set up the headless environment on a Linux VPS (or a platform you recommend). • Unpack the ZIP, install dependencies, and wire up any required environment variables or proxies. • Benchmark slot-booking speed, then fine-tune timing, concurrency, and error handling until it reliably captures the appointment before manual users can. • Hand back a working command or endpoint I can call, plus...
