Jacob M Viefhaus

I’m Jake, a backend-focused developer and cybersecurity specialist passionate about building secure, high-performance systems that withstand real-world threats. Currently pursuing my Bachelor’s in Cybersecurity Engineering at Colorado Technical University (CTU), I combine formal education with years of hands-on freelance work, HackTheBox challenges, and independent projects to deliver robust solutions for startups, agencies, and tech teams.
My expertise centers on:
• Secure backend development (Python, Node.js/Express, Go, Java/Spring, Django/Flask) with clean, scalable APIs, databases (PostgreSQL, MongoDB, Redis), and microservices architecture.
• Advanced cybersecurity implementations: firewalls (iptables, pfSense, custom rules), honeypots (Cowrie, Dionaea), deception tech (Faker-generated data for traps), adversary IP logging & tracking, red-team style offensive defenses, vulnerability assessments, and secure code practices to prevent breaches.
• Cloud development & computing (AWS, GCP, Azure): infrastructure as code (Terraform), serverless setups, secure deployments, CI/CD pipelines, and scalable computing environments.
• AI/LLM/ALM integration: building backend systems powered by large language models (OpenAI APIs, Hugging Face, custom fine-tuning), AI-driven automation, and application lifecycle management tools.
I’ve shipped freelance projects that hardened apps against attacks, automated threat detection, logged malicious actors in real-time, and scaled cloud backends for production use—often reducing vulnerabilities while boosting efficiency. I thrive on complex, security-critical challenges, write maintainable code, prioritize clear communication, and deliver on time.
Whether you need a bulletproof API backend, fortified cloud infrastructure, AI-enhanced secure tools, or custom honeypot/defense setups—let’s discuss how I can secure and power your project. Message me with your brief!
