Your mentor

Hello there. 👋

I’m a veteran software engineer and technical leader with over 20 years of experience building scalable, user-centric solutions across industries including AI, fintech, health tech, and enterprise platforms.

At Undetectable AI, I currently lead engineering efforts for intelligent content detection platforms specializing with integrating Artificial Intelligence powered by large language models (LLMs). I’ve helped scale our systems from handling 50,000 requests per day to over 500,000, optimizing architecture for performance, reliability, and cost. My role bridges architecture, hands-on development, and close collaboration with product and growth teams.

Previously, I founded Barcode Essentials, where I transformed a niche technical concept into a commercially viable, enterprise-grade product. Across my career, I’ve held roles from developer to tech lead to scrum master — consistently combining engineering precision with business alignment.

I’m deeply familiar with modern development stacks including React, TypeScript, Python, and .NET, and I’ve led serverless architecture adoption (AWS Lambda, Azure Functions) in production environments to reduce complexity and improve scalability. I value mentoring, code quality, and building teams that ship fast without compromising craft.

🧠 Focus Areas: Technical leadership, AI system design, scalable architecture, team mentorship
🛠️ Technologies: React, TypeScript, Python, .NET, Serverless (AWS/Azure), CI/CD, LLM APIs
📈 Key Achievements:
– Scaled Undetectable AI traffic 10x in under a year
– Launched multiple full-stack products from concept to market
– Built engineering cultures around

Here’s what you can expect from me. I will...

- Listen and understand your learning goals
- Design a development plan based on your learning goals
- Help you understand difficult concepts
- Provide coding exercises
- Give quality code review feedback
- Help you when you are stuck
- Help you prepare for a coding interview
- Provide a weekly 1 on 1 meeting

Here is what I can help you with:

- Server-side development using either of the following: Node and Javascript, .Net Core and C#, Serverless
- Front-end development using React or Vue
- Mobile app development using Objective-C or Swift
- Unit and Integration Testing
- Components and Frameworks
- Implementing Clean Code
- Design Patterns
- Software design and UML
- General Programming in C#, Javascript, Java, PHP
- Shell scripting
- Productivity and Career Advice

If you are motivated to break into software development, I would be happy to be your mentor. Let’s talk. 🚀

PS. También hablo español 🇨🇴

I was searching for help when I found Jake. He helped me rebuild my foundation and address my knowledge gaps. His tutorials were incredibly helpful in improving and refactoring my code, showing me how to do things better. Jake is an amazing mentor with deep industry knowledge, and he's also a kind person who truly understands you. Now, I know what I need to do to improve myself with tasks and goals that align with my path. I highly recommend him.”
