2. Projects
2.1. Project 1
Job Market Research
Preview:
As I was planning to start job hunting, again, I had the idea of gathering LinkedIn data. My goal was having data of companies to sort, so I can prioritize which to contact… as well as doing some analysis.
2.2. Project 2
Sunken businesses on Google map
Preview:
As I was scraping Google map I discover that 2.7% of all records I have, are of businesses located in the middle of the sea; out of these 2.7%, 73% businesses share the same coordinates [46.423669, -129.9427086]
2.3. Project 3
Data Enrichment
Preview:
I was, indirectly, working for an influencer marketing agency, and I automated a manual task by enriching a database.
My "task" was visit a YouTube channel from a list on a platform called Noxinfluencer, and do a manual check.
Once a channel meet the criteria, I had to manually copy some information to a master Google Sheet.
2.4. Project 4
Scraping for Marketing Agencies and prioritizing reach
Preview:
I made this script when I was looking for a job, I needed a list of companies to contact, but also a way to prioritize who to contact first because of the email sending limitations.
As I collected the data from Google map, I kept enhancing it by adding data from the government of CA, and WHOIS; and I did some analysis at the end.
Example of the email I sent is in the webpage.
2.5. Project 5
Head first on OSINT for an interview
Preview:
An interviewer tasked me with this: "Find out how NSW Govt run tenders for marketing projects"
I had, and still have, no idea on how to do so; but from what I understand, the marketing agency wants work on government projects.
I though, maybe if we initiate an interaction with someone and the government, persuade them to think that our service is good, we could get some favoritism.
So, I went to find one of the high officials, extract as much as I can about him and their surrounding.
2.6. Project 6
Using government FARS data for evaluation
Preview:
After joining a Zoom call on data evaluations, I decided to start a project based on the subject we talked about: reducing fatalities in New York.
I took a large dataset from FARS website, cleaned it, and analyze it.
2.7. Project 7
Serve your customer with your own data
Preview:
This project utilizes the RFM (Recency, Frequency, Monetary Value) model to enhance marketing strategies for different customer segments.
Customer Examples
- Customer A: Recently shopped, purchased 10 items, spent $250.
- Customer B: Last shopped long ago, purchased 2 items, spent $1,000.
Marketing Strategies
For Customer A, we will send coupons to encourage repeat purchases. For Customer B, who has a history of buying high-value items, we will showcase our new line of premium products to re-engage them effectively. This targeted approach ensures relevant communications that drive sales.
