From Non-CS Background to Software Engineer: My 8-Month Journey from Zero

Liberal arts graduate, started programming at 30. My 8-month journey from zero to software engineer.

Why Learn Programming at 30?

Worked in traditional industry marketing for 5 years. Stable job, decent salary (45K/month), but felt stuck with limited growth.

Triggers:

Industry ceiling

Curiosity about tech

Pandemic impact on traditional industries

On my 30th birthday: "If I don't change now, will I regret it at 40?" Answer: Yes.

Month 1-2: Exploration (Finding Direction)

Tried free resources: Codecademy Python, freeCodeCamp, YouTube tutorials. Result: Despite initial frustration, the satisfaction of first working program confirmed: I want to do this!

Talked to 5 engineer friends, researched learning paths, chose: Online courses + Self-study

Month 3-6: Intensive Learning (Quit Job to Focus)

Daily Schedule:

08:00-12:00: Online courses

13:00-17:00: Projects and practice
