How I Taught Myself Marketing, Automation, Web Development and much more by...Doing It!

If everyone else in the company is a brick, then I’m the cement — filling the gaps to make the whole structure solid.

I made a major career pivot.

After years of teaching and creating content around English education, I stepped fully into the world of operations, automation, and business transformation. I took on a full-time role at a small company, and that experience has quietly but completely reshaped the way I think about impact.

I didn’t just change jobs. I shifted how I show up, what I build, and the kinds of problems I solve.

This post is to say: It's absolutely fine to wear many hats, and this is how it has worked out for me.

What I've been doing this past year:

1. Marketing / Sales / Social Media

When I joined, the company’s social media presence was still very raw. TikTok and other platforms were being used just for the sake of posting, not as serious tools for growth.

So I rolled up my sleeves:

  • Refreshed our Instagram into a mini landing page with key info.
  • Created TikTok content formats that actually performed: authentic, face-forward, trust-building.
  • Built pitch decks for direct sales and collaboration invites.

Result: TikTok grew from a few hundred followers to 12,000+, with 1M+ views (with a team, not solo!).

In my first week, I even made a homepage video using just my iPhone 11. Shot and edited in 30 minutes.

2. Automation and Coding

Though my official role was admin, I started teaching myself to code and automate workflows:

  • Used Python + pandas to process massive Excel files into automatic reports.
  • Used Selenium to interact with web apps and save dozens of hours weekly.
  • Built a web app in Next.js so our team could upload product images themselves (no more blurry WhatsApp uploads).
  • Built a tool using BeautifulSoup to scrape data, send pitch decks, and auto-schedule meetings.

3. Accounting

I also… handled accounting.

We’d just launched on a new e-commerce platform (think: eBay-style), but their system lacked financial clarity.

So I pulled from my ACCA background (top of class!) and:

  • Set up a proper accounting system to track all platform inflows/outflows.
  • Navigated a foreign chart of accounts (Sweden-based, very different from UK/Vietnam).
  • Managed timezone quirks and reconciled international payments manually — oddly satisfying.

So what's next?

Here’s my social pitch when someone asks what I do:

“I help small, traditional businesses become Googleable, seen, and trusted with guaranteed conversions. Then I build them a custom automated web app that frees them from outdated systems and third-party dependencies.

My best clients are brick-and-mortar teams with fewer than 12 people and a strong local reputation, but who still run on spreadsheets or manual processes. With what we do together, they typically see 20–30% growth in sales.”

My approach to small businesses

A lot of people are afraid of working in small companies because you have to do everything.

I love it because I get to do everything.

“If everyone else is a brick in the wall, I’m the cement: filling the gaps to make the whole thing stronger.”

In small teams, you need to:

  • See the big picture
  • Understand every stage
  • Deliver reliably across the board

You don’t need to be exceptional at everything: just consistent, adaptable, and tech-savvy.

With modern tools and AI, it’s easier than ever to be that glue.

My view on being a generalist

You’ve probably heard the saying:

“A jack of all trades is a master of none.”

The full quote actually is:

“A jack of all trades is a master of none, but oftentimes better than a master of one.”

In a world changing as fast as ours, I believe this deeply.

We need more Swiss Army Knives, the kind of people who see what needs doing and just do it.

Who I work best with:

  • Established small businesses in traditional sectors, with good reputations but outdated systems.
  • Professionals who want to launch something of their own but can’t afford a full team, and need a clear, scalable setup from day one.

I can:

  • Advise, build, or deliver the system myself.
  • Do it with the cost of one person, but the output of a full team.
  • Leave you with a streamlined, low-maintenance automated setup.

Do I still teach English?

Right now… not directly.

I still love teaching and actively support the community, but I can’t lead live sessions at the moment.

I still:

  • Review every class
  • Grade every essay
  • Keep the quality sharp

Classes are still taught by brilliant instructors like:

Ms. Thảo Lê

  • HCMC University of Education (English Teaching)
  • IELTS 8.5 (Speaking 8.5, Writing 8.0)
  • CELTA Pass B, DELTA Module 1
  • 8+ years of IELTS experience
  • National academic awards (Top 2, Gold Medal)

Ms. Hân Trần

  • Top GPA at Trần Đại Nghĩa & Lê Hồng Phong
  • Foreign Trade University (Top GPA)
  • IELTS 7.5 (Reading 8.5, Listening 8.5)
  • 3+ years of IELTS teaching with CELTA-style plans
  • Public speaking & debate award-winner

If you're levelling up your English, I would love to be part of your journey to make it less of a grind.

On this platform, I talk about:

Marketing, Sales, Social Media

Marketing doesn’t have to be scary or performative.
It’s just helping people understand what you do.

Social media is like a microphone.
What you say into it gets amplified.

I’ll show how non-famous, non-media people can still deliver value, and be recognized for it.

AI, Tech, Automation

I won’t flood you with listicles like:

“Top 10 AI tools you must use”

That’s noise. Knowing the right tool at the right time is what matters.

Questions I’ll help you answer:

  • When should I change tools?
  • Is it worth the switch?
  • Will it actually improve my workflow?

Example:
Spending 20% more might give you 5–10x output.
Spending 80% more for just 10% gain? Not worth it.

From here on out...

If you keep following me, my goal is simple:

To make tech, marketing, and automation less intimidating — and more useful.

I’ll share what’s true.
Sometimes it’s easy to hear, sometimes it isn’t.
But always with the goal of helping you:

  • See the big picture
  • Understand the systems
  • Stop feeling overwhelmed by every new AI headline

Let’s work smarter, not louder.
Let’s build systems that do the heavy lifting — so you don’t have to.

hi there again!

What do you think?

This article might've started as a scribble on the back of a receipt during a bus ride, a spark of something real after a conversation over a pint of Leffe, or notes from a Sunday afternoon client call that left me buzzing with ideas. However it came to be, I hope it found you at just the right moment.

If it stirred something in you, or if you're just curious about anything from automating the boring bits of your business to capturing your quiet magic in a coffee shop shoot. Shall we pencil something into the diary?

I'd love to be on the other end of the conversation.
