How mentorship works →A build is a short set of steps you do on your own computer. You see a result at every step, and you finish with a working AI product, like an agent or a RAG pipeline, that you can run again.
What the research says
3%
of everyone who signed up for an MIT or Harvard course on edX finished it in 2017–18.
Even among people who paid, fewer than half finished.
Source: Reich & Ruipérez-Valiente, Science, 2019 ↗Each page ends with a check you can run, so you know it worked before you move on.
You type, paste, and run every part yourself on your own machine. That is what makes it stick.
When you finish, the product stays on your computer. Reuse it for the next job, project, or idea.
Something you built and can run says more than a certificate. Put it on your resume and keep improving it.
Builds use current AI tools like Cursor and agent skills, for job hunting, learning, and shipping projects faster.
Build an agent in Cursor that writes an honest, tailored resume, cover letter, and form answers for every job you apply to. No resume yet? We build your profile together, step by step.
You keep: the agent folder, the skills, and one application you generated on your computer

Not a wall of videos. Each course walks one system from the first file to production, and the code is yours to keep.
Modules in a deliberate order, so you always know what to learn next.
Slides with voice-over, notes you can reopen, and quizzes that check you understood.
A companion repo for the whole course, written with the practices production code needs.
Same resume for every job, or an AI tool that invents claims? Tell your story once, then get a tailored resume and cover letter where every claim traces to your record.

Picture a chatbot quoting a price your live page never had. Build a RAG stack you can run: crawl pages you chose, store them, and answer from those pages.
Every tip is a short video with a written article beside it, on backend, AI, and production systems. No account needed.
Read a working task agent line by line: the Llm client, seven tools, and the loop that runs them. Then watch a real test where “tomorrow” became 2023, and take on a real-world challenge for your résumé.
A long job can block the next request when your server cannot take it. Learn to name what that job is bound by: a reply from outside, the processor, the graphics card, or the memory.
Walk a small RAG chatbot in the order it runs: main.py, the Rag pipeline, and the Llm client. Then see three live runs, and the three gaps it leaves you as challenges: memory, hallucination, and citations.
“I’ve known Mohammad in a few different roles over the years. He first became my mentor when I was learning frontend development, and now I have the opportunity to work with him as a developer and as my manager. His guidance has been a big part of my growth as a developer. What I really appreciate about Mohammad is that he doesn’t just show you how to do something. He takes the time to explain why something should be done a certain way and encourages you to think through problems yourself. He’s patient, approachable, and always willing to share what he knows, which makes learning from him feel very natural. Today, I’m working alongside him as a developer while also learning backend development and AI engineering with his guidance. Working with him has given me the chance to learn not only from his technical knowledge, but also from the way he approaches problems, makes decisions, and works with a team. I’m really grateful that someone who started as my mentor has become my colleague and manager, and that I still get to learn from him along the way. I’d definitely recommend Mohammad to anyone looking for a knowledgeable developer, a great mentor, and someone who genuinely cares about helping others grow.”

“I’ve been working with Mohammad for over two years. He’s a very skilled web developer and an exceptional teacher. As a full stack developer, Mohammad is able to effectively analyze challenging technical problems and lead his colleagues towards implementing successful solutions. He is a kind and patient teacher with a keen understanding of when and how to push students and colleagues to encourage growth.”
“I have had the pleasure of working with Mohammad on several projects over the past seven years. He is an exceptional full-stack developer with comprehensive expertise in both front-end and back-end technologies. Mohammad has a strong command of modern tools and frameworks, which he applies effectively to deliver organized, scalable, and high-performance applications. In our most recent collaboration, he successfully developed a web application incorporating multiple engineering assessment modules, demonstrating both technical depth and attention to detail. He is consistently approachable, receptive to feedback, and committed to addressing client requirements with patience and the highest standards of quality. If you are considering developing a new application, you will be fortunate to have Mohammad on your team, he is truly outstanding.”

Mohammad — “Moh”
Senior full-stack & AI systems engineer · sole mentor at TechTips
I build and run production AI systems for a living. Every build, course, and tip comes from that work, and I run every mentorship session myself.
Designing and shipping AI-powered products end to end — LLM systems, retrieval pipelines, and production platforms — while mentoring developers through the same work.
Led full-stack platform work: architecture, migrations, APIs, and delivery pipelines so teams could ship reliable products at scale.
Built and shipped web applications across the stack — frontend, APIs, and data — turning product requirements into production features.
Solved engineering challenges by building practical software and automation systems that cut repetitive work and made day-to-day workflows more reliable.
Case studies from production systems I designed and shipped. The same work the courses and builds are drawn from.
I built a snow-route planner that batches Google’s 27-stop cap so a local fleet stops backtracking.
I led TeeTime’s phone AI agent: Twilio, GPT-4, and Zoho, so routine calls stopped sitting on people.
I built a tool that checks golf promo contracts against the official catalog so audits take hours, not weeks.
