Tourist visa from the United Kingdom rejected twice

So I applied for a visa to visit the United Kingdom in January and it was rejected on the basis of the First Denial 4.2 (a), (c) and (e) of Appendix V of the immigration regulations for visitors
* There are not enough strong social, economic and personal ties with Ireland.

I reapplied the following month and I refused in the bases of
– V4.2-v4.10 of appendix v: Immigration rules for visitors
* Only at work for 3 months
* Declaration for one month
* 4.2 (a) (c) of immigration regulations

I am currently living in Ireland with my family and working. The mistake I made at the time of submitting the application was that I had started my work 2 weeks before and I did not have a travel history or enough savings

In the last 2 months I have traveled 4 times within Europe for various events and car shows, I would like to resubmit an application but I need advice on how I can strengthen my application for this moment enter the description of the image hereenter the description of the image here
