End goal: full replacement of legacy Perl system

Current modernization streams:

Migrate email & WhatsApp handling to AI-driven solution

Structured decision-making


What You Will Own

Build production-ready FastAPI services

Define migration architecture

Improve CI/CD maturity

Strengthen infrastructure reliability

Hello, my name is Angel Nikolov and I am the founder of <a href="https://remotefrontendjobs.com">https://remotefrontendjobs.com</a> and <a href="https://remotebackendjobs.com">https://remotebackendjobs.com</a>.
 
 
 I recently noticed some of your advertisements on similar job boards like remotetechjobs and wondered if you’d be interested into featuring an ad on remote frontend and backend focused job boards.
 
 In fact, since both my sites are aggregating multiple different sources some of your advertisements are already listed and you can see some of them here - <a href="https://remotefrontendjobs.com/cl175bfxr9203t8bws2xbbfmt?ref=marketing">DataOps Engineer</a>.
 
 
 Featuring a job now will guarantee top visibility and engagement and will most definitely bring some people your way.
 
 I already have my first customer and for 20 days their advertisement was seen more than a thousand times and was engaged with about 200 times.
 
 
 In case that you want to feature some of your ads for a small early-bird fee, the only thing I will need from you is to let me know which ones and which job board you'd want them on or just send me the job details by email. 
 Let me know if like the idea,
 
 Angel Nikolov

Hi, it's Angel Nikolov again!
	 
	I just wanted to follow up on my last email and ask you if you had time to review the the idea for featuring a job on <a href="https://remotefrontendjobs.com?ref=marketing">https://remotefrontendjobs.com</a> or <a href="https://remotebackendjobs.com?ref=marketing">https://remotebackendjobs.com</a>.
	 
	 
	I would appreciate any kind of feedback!
	 
 Thanks again!
 
 Angel
