Add new tech stack column

Title: Proposal to add a new column named "Tech stack/Skills"

After browsing through the table of companies, I realized that I couldn't determine which technologies they use as part of their tech stack. IMHO, it would be beneficial to have an additional column that describes these technologies, allowing candidates to find their initial match with a company and its opportunities.
