Technology education that goes beyond the syllabus

ATC Technologies is a technology education and IT solutions company. We teach programming the way it is used at work: understand the concept, write the code, build something real, and put it in front of users.

Our job is to close the gap between what a syllabus covers and what the industry expects.

Flagship track

AI Engineering at ATC

From Generative AI to Agentic AI. Ten stages that take you from writing Python to shipping AI systems that retrieve, reason and act.

  1. The working language of AI. Data handling, APIs, async code and a clean project structure.

  2. How models generate text, code and images, and where they fit inside real products.

  3. Tokens, context windows, model choice and calling large language model APIs from your own code.

  4. System instructions, few-shot examples and structured outputs your program can parse reliably.

  5. Turning text into vectors that capture meaning, and measuring how similar two pieces of text are.

  6. Storing embeddings in vector databases and retrieving the closest matches quickly at scale.

  7. Retrieval-augmented generation: answers grounded in your own documents instead of the model's guesses.

  8. Model Context Protocol: connecting models to tools and data through one standard interface.

  9. Models that plan, call tools and work through several steps toward a goal.

  10. Multi-step and multi-agent systems with memory, guardrails and evaluation, built for production.

Stage 1 of 10

Python

The working language of AI. Data handling, APIs, async code and a clean project structure.

The track ends where industry work begins: production AI applications that are tested, observable and useful.

Why learners and teams choose ATC

No rankings, no promises we cannot back. Here is what we actually do differently, and why it matters to you.

Talk to ATC

  • Practical learning

    Every concept is followed by code you write yourself. It matters because skills stick through use, not through notes.

  • Real projects

    Courses end with something that runs. It matters because a working project says more in an interview than a certificate.

  • Original technical content

    ATC writes its own study material and lessons. It matters because the material matches exactly what is taught in class.

  • Experienced training

    Classes are led by trainers who teach and build software. It matters because you learn how things are done, not only what they are called.

  • AI Engineering

    A structured track through RAG, MCP and agents. It matters because these are the skills teams are hiring for now.

  • Internship opportunities

    Internships may be offered alongside current programs. It matters because supervised project work turns learning into experience.

Don't just learn. Build.

Every ATC project follows the same cycle professional teams use.

  1. 1ConceptDefine the problem and who it is for.
  2. 2DesignPlan data, screens and structure.
  3. 3CodeImplement in small, working pieces.
  4. 4TestCheck it works, then fix what doesn't.
  5. 5DeployPublish it and share the link.

  • Java applications

    Console and backend applications built on object-oriented design.

  • Python applications

    Automation scripts, utilities and API-driven programs.

  • Full stack applications

    Web applications with a database, backend and user interface.

  • Data science projects

    Analysis and models built on real-world datasets.

  • RAG applications

    Question-answering systems grounded in a document collection.

  • AI agent applications

    Agents that call tools and complete multi-step tasks.

Learner project screenshots will appear here as they are published with the learners' permission.

Turn learning into experience

ATC internships put your training to work on supervised development projects. Depending on the current program, 3-month and 6-month internships may be offered.

You finish with work you can show: code on GitHub, a project you can explain, and a clearer idea of how development teams operate.

  • 3 monthsFocused project internship
  • 6 monthsExtended development internship
