Cover image for Executive Review: Global Aircraft Manufacturing

Executive Review: Global Aircraft Manufacturing Intelligence Dashboard The Global Aircraft Manufacturing Intelligence Dashboard demonstrates how modern Business Intelligence can transform complex aviation datasets into strategic insights that support executive decision-making. By integrating production, delivery, market share, and regional performance data from leading aircraft manufacturers into a unified Power BI environment, the solution provides stakeholders with a comprehensive view of industry performance and emerging market trends. The analysis indicates that Airbus and Boeing continue to dominate the global commercial aviation market, while manufacturers such as Embraer, Bombardier, Dassault Aviation, Gulfstream, and COMAC continue to strengthen their presence across regional, business, and emerging aviation segments. Through interactive visualizations, users can evaluate production performance, delivery trends, market distribution, and competitive positioning to better understand the evolving dynamics of the aerospace industry. Beyond visualization, the dashboard serves as a strategic decision-support platform by enabling organizations to monitor key performance indicators, identify growth opportunities, anticipate market shifts, and improve forecasting accuracy. The ability to consolidate multiple data sources into a single, reliable reporting environment significantly reduces manual reporting effort while improving data consistency and operational visibility. At Intersect Analytics, we specialize in designing enterprise-grade Business Intelligence solutions that convert fragmented business data into actionable intelligence. Our expertise spans Power BI Dashboard Development, Financial Analytics, Executive Reporting, SQL Data Modeling, Python Analytics, Excel Automation, Office Scripts, Power Automate, Predictive Analytics, and Data Engineering. Every solution we develop is tailored to enhance reporting efficiency, strengthen decision-making, and support long-term business growth.

Cover image for A hands-on overview of CAI,

A hands-on overview of CAI, an AI-assisted cybersecurity agent framework configured and explored in a Linux terminal environment. The demonstration focuses on how AI agents can be organized and used to support different areas of cybersecurity testing, analysis, and research. The walkthrough covers command-line navigation, available help options, agent selection, model configuration, and the use of specialized security agents. It includes a closer look at DFIR-focused agents for digital forensics and incident response, along with other agent categories designed for bug bounty research, red team activities, network security, reverse engineering, Wi-Fi security, and reporting. The setup also highlights parallel agent configuration, showing how multiple AI-driven security agents can be prepared for structured analysis and task separation. This makes the environment useful for handling different cybersecurity activities in a more organized and scalable way. Overall, the work reflects practical experience with AI-powered security tooling, terminal-based security environments, agent configuration, cybersecurity automation, and ethical AI-assisted security research.

Cover image for Conducted an automated security assessment

Conducted an automated security assessment of a locally-hosted large language model, Dolphin 3.0 (Llama 3.1 8B), using Garak, NVIDIA's open-source LLM vulnerability scanner. The model was served through LM Studio's OpenAI-compatible REST API and tested from a Parrot OS environment running in VirtualBox. Configured Garak to target the model via a custom REST generator configuration, handling endpoint routing, Bearer token authentication, JSON response parsing, and extended timeouts for local inference. Executed nine distinct probe categories against the model, covering DAN jailbreaks, prompt injection, encoding-based bypass, malware generation, latent injection, real toxicity prompts, continuation attacks, grandma exploits, and package hallucination. The assessment identified that Dolphin 3.0, an uncensored model with no built-in safety guardrails, was vulnerable across the majority of probe categories. Findings were documented per probe, distinguishing where the model resisted versus complied, and translated into a clear, layered explanation of each attack type and its real-world security implications. Delivered the work as a complete, reproducible walkthrough, including environment setup, tool configuration, probe execution, and results interpretation, suitable for both technical practitioners and stakeholders newer to AI security.

Cover image for AI security research project focused

AI security research project focused on prompt injection risks in LLM-powered applications. The work involved testing how AI systems handle malicious or hidden instructions inside user inputs, documents, webpages, and other untrusted content. The assessment explored risks such as instruction bypass, guardrail failure, data leakage, unsafe tool use, and AI output manipulation. It demonstrated the importance of testing the full AI application, not only the model, especially when connected to files, APIs, RAG systems, browsers, or autonomous agents. Skills demonstrated: AI red teaming, LLM security testing, prompt injection analysis, guardrail evaluation, threat modeling, and secure AI deployment. Tool: Spike

Cover image for I conducted an authorized AI

I conducted an authorized AI security assessment of Lily Cybersecurity 7B to evaluate how effectively a hardened system prompt could resist jailbreak and prompt injection attacks. Using Prompt Fuzzer, I ran 15 attack techniques against the model. The system prompt successfully blocked 8 attempts, including most roleplay and social engineering attacks. The successful bypasses mainly used translated or altered wording to disguise the intent of the request. This project demonstrates why system prompts should be supported by input validation, moderation, output filtering, and continuous AI red team testing.
