How DataMites Played a Role in Vitchco Raj’s Artificial Intelligence Career

Vitchco Raj’s journey shows how structured learning and hands-on practice can support a strong start in the Artificial Intelligence Career. The following Q&A highlights his learning experience and career growth.

Q1. Can you briefly introduce yourself and your professional journey?

I have around three years of experience in the field, including my learning phase in data engineering. I started my IT journey after a referral from my brother and joined a startup company in Chennai as an intern. Later, I worked as a Data Engineer for around two years. After that, I switched companies, and I am currently working as an AI Engineer at Apptomate.

Q2. When did you start your data engineering journey?

I started my structured learning in 2023 and joined a DataMites training program in January. Within a few months, I received my first job offer in April, which marked the beginning of my professional career.

Q3. How important was training in shaping your career?

Training at DataMites played a major role in building my foundation. It helped me understand data engineering concepts and data processing fundamentals, which later helped me perform better in interviews and real-world projects.

Q4. What was your first role in the IT industry?

My first role was as a data engineer intern in a startup company based in Chennai. It was a three-month internship that later converted into a full-time opportunity.

Q5. What is the role of a data engineer in AI systems?

A data engineer collects, transforms, and prepares data that is used to train AI models. This includes ETL processes and ensuring the data is clean, structured, and usable for machine learning systems.

Q6. What kind of data challenges have you faced in real projects?

One of the biggest challenges was handling unstructured data like emails. These datasets often contain invalid characters and inconsistent formats, making it difficult to process and standardize data across different clients.

Q7. How did you handle different data formats across organizations?

We created a generic processing system that could handle multiple formats from different clients. This required writing flexible and reusable code to ensure consistency in data processing.

Q8. What tools have you worked with in your projects?

I have worked with tools like AWS and Elasticsearch. Elasticsearch helped in indexing and querying large datasets efficiently, especially in search-based applications.

Q9. Have you worked with SQL and databases?

Yes, I have worked with PostgreSQL and MySQL. I also learned about vector databases, which are becoming very important in modern Artificial Intelligence applications.

Q10. What is your experience with machine learning models?

In my early projects, I worked with basic machine learning concepts. However, most of the model training and optimization tasks were handled by specialized team members, while I focused on data preparation and data pipeline development.

Q11. Have you worked with LLMs like GPT?

Yes, we used GPT models like GPT-3.5 and GPT-4 for data extraction and query processing. We also used LangChain to structure prompts and improve output quality.

Q12. What is Retrieval-Augmented Generation (RAG) and how are you using it?

Retrieval-Augmented Generation (RAG) is a process that combines retrieval systems with language models to provide more accurate and domain-specific responses. I am currently working on a chat system powered by GPT using RAG architecture.

Q13. How do you stay updated with new technologies?

I continuously learn through platforms like Udemy, Coursera, DataCamp, YouTube, and LinkedIn. I also use ChatGPT to create learning paths and explore new concepts quickly.

Q14. What role does self-learning play in an AI engineering career?

Self-learning is essential because technologies evolve rapidly. Without continuous learning, it becomes difficult to stay relevant in the industry.

Q15. What advice would you give to aspiring AI engineers?

Focus on fundamentals like SQL, databases, and data processing. Learn cloud platforms and vector databases. Most importantly, keep learning consistently because the field is constantly evolving.
