I’m building a product around an ESP32 and need a clean, reliable firmware layer that handles both Bluetooth Low Energy and Wi-Fi. The two core responsibilities are device connectivity and on-demand data transmission. Here’s what I expect the software to do: • Seamlessly switch between or simultaneously maintain BLE and Wi-Fi links to smartphones and tablets. • Expose a simple, well-documented API so the application layer can request or push data whenever needed rather than streaming constantly. • Keep connections stable, recover gracefully from dropouts, and report status events (connected, disconnected, data sent, error, etc.). • Offer secure pairing/authentication on BLE and WPA2 on Wi-Fi. • Remain lightweight so sleep routines and future ...

I need a seasoned VoIP specialist to take my deployment from zero to fully operational. I will not be supplying configuration files, trunks, numbers, or even the initial account—everything has to be sourced, built, and verified by you. The finished system must speak SIP end-to-end so that soft-phones, desk phones, or mobile clients can register and place calls immediately after hand-over. I expect you to: • Create or configure the account, secure it, and document all access credentials. • Provision at least one SIP trunk or equivalent solution so the platform can dial in and out of the public network. • Set up a clean dial plan with working inbound and outbound routes and test calls in both directions. • Provide two sample SIP extensions (one desktop, on...

I need my production Kubernetes cluster moved from Calico CNI to Cilium CNI with zero-downtime, production-grade encryption and greatly strengthened security controls. The main driver behind the change is enhanced security, so the work must enable wire-speed, node-to-node encryption, fine-grained network policy enforcement and any Cilium eBPF features that raise the overall security posture. Because we do not yet run a monitoring stack, part of the engagement is to stand up a new observability layer. Leveraging Hubble is the natural starting point, and I am open to whichever back-end you prefer for metrics and dashboards—Prometheus/Grafana, OpenTelemetry, or another first-class option—provided the end result offers clear, real-time visibility into flows, latency, dropped pac...

Senior Zscaler engineer needed to guide me over the shoulder while I rebuild the foundational pieces of our ZPA/ZIA setup. I drive the consoles; you advise in real time and explain the why behind each setting. Context: A current implementation works but isn't scalable, security-focused, or aligned with best practice. Goal is to reset the foundation so those problems don't carry forward, built to a strong security bar, with a structure that scales cleanly across employees, contractors, admins, and third parties without rework. Constraint: Okta SSO is operational and out of scope. ZIdentity group/role binding is on a separate track. Work fits around both. In scope: - Hardened pre-auth machine tunnel with the strongest realistic device trust model - Least-privilege pre-logon acc...

I need a certified cybersecurity professional to determine whether my personal Android phone has been subjected to unauthorized access and to help me regain full, lawful control of every component that may have been touched. The device is the only confirmed target right now; however, if traces lead to email or social channels I will widen the scope with you. Your investigation must be forensically sound so that any evidence you uncover can stand up to scrutiny should I decide to take legal action. I am expecting a hands-on approach that covers log collection, malware/spyware scanning, vulnerability mapping, and clear recommendations on how to close every gap you find. Where recovery steps are needed—password resets, two-factor reconfiguration, data restoration—I want you ...

Our infrastructure is ready for a major uplift: I am replacing a flat WatchGuard/Ubiquiti environment with a full Cisco Meraki hub-and-spoke SD-WAN. The topology is straightforward—one headquarters that will act as the primary hub, a DR site that will serve as a secondary hub, and four branch offices that will connect as spokes. Here is what I need from you: • Design a Meraki architecture that introduces proper VLAN segmentation, Auto-VPN, traffic shaping, and advanced security while mapping cleanly to the existing IP ranges. • Produce a configuration set for MX security appliances, MS access/distribution switches, and any required SFP or PoE considerations so the cut-over is as close to “plug and play” as possible. • Create and document a migrati...

I recently added a new SIP trunk to my setup—FreePBX 15 sitting behind a Kamailio SBC—but the trunk will not register and no outbound calls complete. I need someone who understands FreePBX 15, Asterisk SIP settings, and Kamailio routing to: • Diagnose why the trunk fails to register with the provider • Configure the correct authentication, codecs, and SIP headers so outbound calls connect cleanly • Provide a brief step-by-step summary of the changes you make so I can replicate them in the future You will have to work via Anydesk, you won't be able to directly connect to our server.

I need a thorough security audit that examines our network perimeter, our internally-developed web and mobile applications, and the policies we rely on to stay aligned with compliance and governance standards.

I need an experienced ethical hacker to dive deep into my web application and pinpoint any security weaknesses before they can be exploited in the wild. The sole objective is to identify vulnerabilities, not to gain or provide unauthorized access for malicious purposes. You’ll have full permission to run a comprehensive penetration test against the live site (or a staging clone, if you prefer). Feel free to use the tools you trust most—Burp Suite, OWASP ZAP, Metasploit, custom scripts—so long as the process is legally compliant and doesn’t disrupt service for genuine users. At the end of the engagement I expect: • A clear, well-structured report detailing every vulnerability you uncover, proof-of-concept evidence, risk ratings, and practical remediation advic...

I want a seasoned security professional to probe my site from every angle and show me—plainly—where a hacker would slip in. My main worry is outright breaches, not just compliance check-boxes, and at the moment I only have the usual basic plugins and a standard SSL certificate in place. You’ll need to run a full vulnerability assessment and light penetration test, review server and application configurations, and evaluate any code that touches the public web. Feel free to bring out Burp Suite, OWASP ZAP, Nikto, or whatever toolset you trust; I’m interested in real-world exploitability, not generic scanner output. Please deliver: • A concise report detailing each weakness, its risk level, and clear remediation steps • A prioritised action plan I c...

Essential features for customers • Live and historical uptime / downtime, traffic statistics and error logs presented in clear dashboards. • Remote network-settings changes plus bandwidth-monitoring tools surfaced through an intuitive GUI. • A captive portal module so hotels and similar venues can issue guest Wi-Fi credentials on the fly; voucher or self-registration flows are both acceptable a...

Our organisation runs a geographically-distributed Wide Area Network and I want independent confirmation that the data moving across it cannot be intercepted, decoded, or manipulated. The engagement is limited to traffic analysis and sniffing on the live WAN links; firewall rule-sets and router configurations are out of scope unless you discover something during capture that clearly ties back to them. Scope • Perform lawful, ethical interception of packet flows on agreed WAN segments. • Analyse captured traffic for clear-text credentials, session fixation, protocol misconfiguration, or other weaknesses that could lead to privilege escalation or data leakage. • Attempt non-disruptive proof-of-concept exploits only where traffic analysis indicates a realistic attack pat...
