my FITNATURE is coming to town!


Today I am delighted to see Joemary Leung, a Personal Trainer, Online Coaching, starts her new business: my FITNATURE.

my FITNATURE is an athleisure brand for people to bring out their uniqueness through wearing our fitness wears. Joemary seeks for me assisting her to work out her business with Shopify, while the world is still concerning COVID-19 striking everyone business. She believes in her products and really look forward to share it with people who need it.

It is not an easy start to anyone, as investing right now is just like investing in an unknown result. Yet, I try my best to clarify her for questions she feel unclear about:

  • How online business works?
  • How Shopify works?
  • What is needed to run an online business?

I shared with her what cost would need for running a e-store, sharing the focus of her preparation and what else technical parts that I can offer my services.

We confirm the business relationship virtually at night around 11pm, the majority journey are through email / Whatsapp and Google Meet, until a week before the site launch.

Honestly Shopify platform cover most server side functionality and I focus on the visual / theme customisation to match my FITNATURE’s brand identity. And also setup the related tracking, site launch preparation. And I believe the hardest part is the Shopify + Facebook Page integration, which is a headache recently when I work with various parties. There are problem screening over the Internet and we are not lucky enough to avoid this, resulting the FB related integration is delayed.

Thanks Joemary for her kindness patience and we work hard to finalise the site to get it well ready for launches and it is great the site can launches smooth in a sunny Sunday!

It is just the beginning, setting up a e-store is not hard nowadays with various tools and platform available. But keeping the business success in such a pandemic situation is challenging to every ambitious new merchants. I wish I can provide an affordable services to support my clients and help their business continuous grow with overcoming any challenges in such abnormal Era~

Something about Shopify Support and Shopify Expert / Shopify Partner

Being a Shopify Expert / Shopify Partner, there are questions relates to this role often from my clients and my friends. And I try to share some and welcome feedback.

First of all, Shopify Expert are people who experiences and solid work history on various Shopify projects, across store setup / theme development / marketing and app development. I started my Shopify affiliate journey since 2014, and once reach 5 clients, I applied to be a qualified Shopify Expert. I also wrote a blog shared the reason for seeking Shopify Expert help for Shopify store setup.

For last 6 years, I have managed more than 10 clients, although I cannot work with each clients every moment. Yet I am open for them to connect with when they have questions for their store or even their business, act as a helpful hand if they seek for advices.

Shopify is a listed company, providing the SaaS E-Commerce platform which help store owner setup their store in a handy way. They do have a support team for handling various store owner issues. So they provide well documents to store owner / Shopify partner for theme / app / development etc. They have Shopify Forum for people to raise questions. Official FAQ system so as to shortlist common questions. And ultimately they offer Live Chat / Email / Phone call support. Although with various support channel, it cannot replace the need for Shopify Expert.

A proper Shopify Expert work with you for business, to help your business grows, care your difficulties and provide solution and even implementation. There are Shopify Expert who care dollar sign and initiate various development works, or someone like me treat freelancer as a personal habit for building various stores to help different business, or to learn how to do business by mean of offering my web development skills. Shopify Expert should have skill set in theme development, store configuration to facilitate the business, they work close to the clients and know their store well. Meanwhile, Shopify Support represent Shopify, they provide support which sometime requires investigation from backend, where Shopify Expert cannot access. Shopify Support often not close to your business, if you are unluckily, you may even reached out from a Shopify Support who mis-understood your issue and brought you walk through the garden and keep sharing information that not useful and off the topic.

A good Shopify Expert should be able to communicate well with the client in order to understand their situation better and able to think on behalf of the client so as to work out the things that work right to the client. I am not yet well in communication and time is the most scarcity item which cause me fail to commit some client raised demand, it is the problem of solo proprietor.

If you are a Shopify store owner. I look forward you can find your right Shopify Expert as a partner, they are happy to build a relationship with you especially if you can let them help you setup your store (as we have a little commission scheme as incentive to be active in Shopify community).

Dropshipping – 1st attempt fail

After 2.5 month past, I decide to pause my store, My Quali Stuffs and re-strategise the way to go.

There are couples aspect that make me consider to pause:

  1. I get very low traffic
  2. I get opinion from friends that, the items I have in the store is fun, but won’t buy because of lack of confident
  3. The items are not unique, and price not competitive

But honestly those facts are just make me consider until I try experience placing a real order for a bag, to replace my own bag, and the experience is worse:

  1. I ordered a bag from AliExpress
  2. The order being processed after 3 days
  3. It takes another few days to wait for starting the shipment
  4. And it requires estimation of 20 days for delivery
  5. And ultimately …. I waited for a month and the items still not being received

This experience make me not confident enough to keep such business model. Hopefully my store does not gain enough attention and there are no order from anyone, so I am not suffer from any delivery issue or customer complaint. And I think it is not really a good start to just run drop-shipping without having a stable supplier to support your business.

Therefore, it is still not the end day of My Quali Stuff, I am just aim to tackle on the lesson I learnt: I need a stable supplier, so I am now trying to approach some physical store who does not have online store for their online business, I am trying to compensate what they miss and try leveraging my store as their online store, to holds their product online so as to attract more of their potential customers.

I hope I can come up some update soon : )

My Quali Stuffs – My own Shopify store – Be my client’s perspective to look at E-Commerce

My Quali Stuffs:

More about Shopify:

People who know me would likely know I am a big fan of e-commerce, along with my career and the time before reaching my 34th, I have dedicated myself to e-commerce related role, acquiring as much web knowledge as possible and help my clients setup various e-commerce business.

And I come to a moment, thinking of how to learn from my clients’ success stories and work out my own version, so, My Quali Stuffs arises.

My Quali Stuffs, a drop-shipping based online business, powered by Shopify. I know Drop-shipping would be the simplest step to run an online business when I having no connection with any suppliers, which is different from all of my clients that they have some wonderful suppliers or they are themselves the suppliers of the items they sell. And I look forward with such self-experiencing e-business, I can put myself in a much closer position and look at e-business from client’s perspective, tackling the online marketing with real exercise, putting my real money on a real investment and see how it goes.

No one can tell it would be an easy job, my advantage would likely be skipping the cost for an IT guys / developer, or familiar with various tools / marketing channel with lack of real hand-on experience.

I would love to share more update and maybe some day you may see the success of my story, or the fall of my business and I have to work harder for my original business.

Github remove Weak cryptographic standards

Since 23 Feb 2018, I find one of my work operation keep failing. In my workspace I have a Jenkins checkout Git repo which further run bower and Gulp for dependencies. It keeps saying Github fail to connect. The error say the HTTP protocol is not support, or cannot make HTTP connection. And turn out we find we fall to one of the scenario that our Jenkins server no longer able to get things from Github because Github disconnect the support of the following weak cryptographic standards:

  • TLSv1/TLSv1.1
  • diffie-hellman-group1-sha1
  • diffie-hellman-group14-sha1


Since the incident, I aware the linux server we have for our Jenkins is already kind of old.

Turn out we have to upgrade our Linux to have latest openssl, libcurl and git using `yum update openssl libcurl git`

I though the story is about to end after my colleagues upgraded the changes. Another side of the workspace dev buddies start complaining the failure of building the application. And they are actually working on VM which is CentOS 6.

After checking, our VM has CentOS 6 with openssl in 0.9, git with 1.7.2 version, both of them do not support TLS 1.2 (the version that supported by github from now on)

Therefore the way to fix the issue is to update these modules. Sadly, updating them in CentOS is not straight forward, and here are some command I ran to get them upgrade:

Update openssl (you may need sudo):

# cd /usr/src
# wget
# tar -zxf openssl-1.0.2-latest.tar.gz
# cd openssl-1.0.2a
# ./config
# make
# make test
# make install
# openssl version

If you still find the version is incorrect, check which openssl to find which openssl is pointing at

Update GIT:

# yum install
# yum install git

Hope this helps.
