Important note:
While the role includes experience with technologies such as .NET Core and PostgreSQL, our client places greater emphasis on candidates who have worked in fast-growing fintech startup environments and who are deeply familiar with the JavaScript / TypeScript ecosystem. Hands-on experience operating in high-growth, product-driven fintech companies and building scalable API-based platforms in a JavaScript / TypeScript environment will be considered more critical than specific experience with individual technologies.
