MLOps & Practical AI: "Built and containerized (Docker) several machine learning models (using scikit-learn, TensorFlow) for classification tasks, establishing a CI/CD pipeline with GitHub Actions to automate testing and deployment, simulating a production MLOps environment."
AI Agents & LLMs: "Developed conversational AI agents using LangGraph to create stateful, multi-step workflows, integrating locally run LLMs via Ollama. Explored Retrieval-Augmented Generation (RAG) to build a context-aware Q&A system on private documentation, improving answer accuracy over naive prompting."
Deep Learning Fundamentals: "Implemented neural networks (CNNs, RNNs) from scratch and using high-level frameworks to solve image and sequence-based problems, solidifying understanding of backpropagation, optimization, and regularization techniques."
Consolidated: Studium Cyber Security, Detection, Protection, Studium Cybersecurity
Threat Detection & Protection: "Configured a home lab SIEM (Security Information & Event Management) using the ELK Stack (Elasticsearch, Logstash, Kibana) and Wazuh to aggregate logs, create detection rules for simulated brute-force and malware attacks, and set up automated alerts."
Secure Architecture: "Studied and implemented core cybersecurity frameworks (MITRE ATT&CK, Zero Trust), applying them to harden cloud and container environments, including network segmentation, least-privilege access controls, and secret management."
Consolidated: Studium Platform Engineer, Studium MSP, Studium n8n, Studium Go Lang
Infrastructure as Code (IaC) & Automation: "Used Terraform to provision and manage cloud resources (AWS/Azure sandbox), defining reusable modules for scalable infrastructure. Automated complex, multi-step operational workflows using n8n, integrating APIs, databases, and conditional logic to replace manual processes."
Backend Development for Platforms: "Learned Go (Golang) to understand systems programming, building concurrent services and CLI tools. Focused on Go's strengths in performance and networking relevant to cloud-native and platform tooling."
Managed Service Provider (MSP) Concepts: "Analyzed MSP operational models (ITIL, RMM tools, PSA software) to understand service delivery, ticket lifecycle management, and client-centric IT infrastructure management at scale."
