    I have a working C++ application that currently relies on hard-coded values; I now need that logic moved into a subroutine capable of reading the same data from an external file instead. Your job is to extend the existing subroutine so it accepts file input, integrates the data seamlessly into the program’s current flow, then compile and run the whole project on a free Red Hat Enterprise Linux environment (Fedora, CentOS Stream or any other RHEL-compatible distro is fine). You will receive: • The current source tree and a brief note on where the new functionality plugs in. • A sample data file that illustrates the expected format. What I expect back: • Updated source code with clear in-line comments that show where changes start and end. • A Makefile (or...

    I need an experienced DevOps engineer to streamline my AWS infrastructure. The immediate priorities are automating all deployment processes, standing up a clean CI/CD pipeline, and wiring in robust monitoring with alerting. The stack lives entirely in AWS, so familiarity with its core services—EC2, ECS or EKS, IAM, CloudWatch, and related networking components—is essential. Terraform is the infrastructure-as-code tool of choice; everything must be defined, version-controlled, and repeatable in Git. Deliverables • Terraform code that provisions the complete environment from scratch • A CI/CD pipeline (GitHub Actions or similar) that builds, tests, and promotes to staging and production automatically • Monitoring dashboards and alert rules in CloudWatch (or e...

    I’ve decided to spin up a fresh MyBB community and need someone to take me from a blank hosting account to a fully operational forum.

Beyond those essentials I’m open to suggestions. I’m not yet sure which plugins, if any, would truly add value, so I’ll rely on your experience to recommend and configure only what’s genuinely helpful (security, spam control, quality-of-life tools, etc.).

    Title: Developer Needed to Build Monitoring Platform Using EZVIZ API / SDK (Fixed Price Project) Description Hello, My name is Alex. I run a security company operating a monitoring center.

We access them remotely using EZVIZ PC Studio, which is mainly designed for home or small installations and not suitable for professional monitoring. Important note: EZVIZ H9C cameras do not provide RTSP streams, so the system will likely need to use the EZVIZ Developer Platform (Cloud API / SDK). What we want to build We want a centralized monitoring platform where our operators can monitor cameras from many different sites. Ideally, the sys...

All attempts to start the cluster and access prism has failed.

    I need an experienced security engineer to harden our multi-tenant SaaS product, prepare us for HIPAA and SOC 2 Type II audits, and stay on call for incident response. The stack runs primarily on AWS, Azure or GCP, with containerised workloads orchestrated by Kubernetes. Day-to-day you will probe our web apps and APIs with Burp Suite and OWASP ZAP, script automation in Bash, and guide the team as we fold security controls into an established Git-based CI/CD pipeline. Key objectives • Run a full penetration test against the platform, documenting exploitable findings against the OWASP Top 10 and cloud-specific misconfigurations. • Configure vulnerability scanning (Nessus, Snyk, Trivy) and wire SAST, DAST and dependency checks into our build pipelines. • Implement and v...

    I’m expanding our infrastructure team and need an India-based engineer who already lives and breathes Zabbix. This is a permanent role, not a short contract, so I’m looking for someone who can take full ownership of our monitoring platform and grow it with us. To hit the ground running you will: • Build and fine-tune end-to-end system monitoring on fresh and existing hosts. • Create intuitive, real-time dashboards that speak to both ops engineers and executives. • Craft actionable alert rules that work consistently across Linux, Windows and macOS environments. Only an expert level of Zabbix experience will work here; you should be comfortable architecting high-availability setups, optimizing proxies, and scripting advanced item prototypes without hand-hol...

    Nginx Powered Live TV App
    3 days left
    Verified

    I need a straightforward Live TV streaming solution built around an Nginx media server and two native clients—one for iOS and one for Android. The heart of the job is getting a rock-solid stream from my existing sources, pushing it through Nginx (with the RTMP or similar module you prefer), and playing it back smoothly on both mobile platforms with minimal latency. Here’s what I’m picturing: • Server side – Tweak or rebuild the current Nginx setup so it can ingest my Live TV feed, handle adaptive bit-rate encoding, and expose HLS/DASH endpoints. – Secure the streams (token or key-based is fine) so that only the apps can view them. – Provide clear documentation so I can add or remove channels later without touching the code. • Mob...

    I’m looking for a straightforward, cloud-hosted space where my team can upload, store, and exchange documents without exposing anything publicly. Every file must stay invisible unless the owner explicitly grants access to selected users, and authentication will rely solely on a classic email-and-password workflow. Core needs • Smooth upload/download of PDFs, DOCX, XLSX, PPT, and similar formats • Invite-only sharing—no public links; only the people I name can see or retrieve a file or folder • Responsive web interface that works just as well on a phone as on a laptop • Password reset, change-password, and basic profile management built in • Admin view to track users, review storage consumption, and revoke or grant access instantly Tech g...
