Hi, I just got into tech (actually 1 year in but I still feel like I don't know anything).

I learnt python, R, SQL, Tableau and concepts in Data Structures, Algorithms.

[Just the Basic level of the listed.]

But I can't write my own programs on python or create anything.

I was hella impressed by your microprocessor project, and when I took up tech (ai and data science) I assumed I would do something like that or at least code.

Now, I am just venting but where do I start, how do I make projects what are some interesting projects, what should I learn? A lot of my seniors tell me to have a wide range of knowledge like focus on one thing by depth but add other things. For example: you can study data analytics in depth but have some knowledge in ethical hacking and web development etc. Like an all rounder.

Wow ok a lot to unpack here, I'll get started

Lots of places recommend that you start with Arduino, as there are a lot of good tutorials out there. I somewhat disagree

I think that raspberry pi is better because it's usually a lot cheaper to buy the stuff you want to play around with

But an even cooler way to do it, go to wokwi.com and start a project on a Raspberry Pi Pico (make sure it's the micropython version) and then you can get started there

Google something like "Blink led with Pi Pico micropython" and there will be a tutorial or two

Then, once you've played around for a while you can buy a Pi Pico for very little money and see your stuff work irl!

If you need any more help or have any questions, feel free to DM me and I'll see what I can do

Don’t try to memorize formulas or force yourself to master every algorithm. Instead, focus on how data science is used in the real world:

In marketing to measure campaign performance

In HR to predict employee attrition

In finance to detect fraud

In supply chain to optimize delivery routes

Relating concepts to your current domain makes learning not only easier but more enjoyable.

Step 4: Work on Projects, Not Just Theory

Even if you’re still learning, try to work on mini-projects using publicly available datasets from Kaggle or government portals.

For example:

Analyze sales data and build a forecast model

Explore customer churn patterns for a telecom company

Create a dashboard showing COVID-19 trends

These projects will become part of your portfolio, making you stand out when applying for jobs.

Step 5: Keep Learning, Keep Growing

The field of data science evolves fast. Stay updated by:

Following data science communities on LinkedIn

Watching free courses and tutorials

Do I need a degree to become a data scientist?

While a degree can be beneficial for becoming a data scientist, it is not strictly necessary. Many successful data scientists have transitioned into the field from various backgrounds and have acquired their skills through alternative means. Here are some pathways to becoming a data scientist:

Traditional Pathways

Degree in a Relevant Field: Degrees in fields such as computer science, statistics, mathematics, engineering, or data science provide a strong foundation.

Advanced Degrees: Many data scientists hold master's degrees or PhDs, which can offer deeper knowledge and research opportunities.

Alternative Pathways

Online Courses and Certifications: Offers programs in data science and related fields.

Bootcamps: Intensive, short-term programs like those from General Assembly, Springboard, and others can provide practical, hands-on training.

Self-Study: Learning through books, tutorials, and online resources can also be effective. Key topics to study include programming (Python, R), statistics, machine learning, and data visualization.

Essential Skills and Knowledge

Programming: Proficiency in languages like Python and R.

Statistics and Mathematics: Understanding of statistical methods, probability, and linear algebra.

Machine Learning: Knowledge of algorithms and frameworks like TensorFlow, Scikit-Learn, and Keras.

Data Manipulation: Experience with SQL and tools like Pandas for data manipulation.

Data Visualization: Skills in creating visual representations using tools like Tableau, Matplotlib, or Seaborn.

Domain Knowledge: Understanding the specific industry or field you are working in can be highly advantageous.

Building Experience

Projects: Working on real-world data science projects can help build a portfolio. Kaggle competitions and open-source contributions are great ways to gain experience.

Internships and Freelancing: Gaining practical experience through internships or freelance work can be very valuable.

Networking: Joining data science communities, attending meetups, and connecting with professionals in the field can provide guidance and job opportunities.

Continuous Learning

The field of data science is constantly evolving, so continuous learning and staying updated with the latest trends, tools, and techniques is crucial.

In summary, while a degree can provide a structured path and a strong foundation, many alternative pathways exist for becoming a data scientist. Practical experience, continuous learning, and developing a strong portfolio are key components of success in this field.
