[05] — FAQ
FAQ
Where are you based?
I am based in Buenos Aires, Argentina (UTC-3), and work fully remotely.
Can you work with international or US-based companies?
Yes — I work as an independent contractor through my Wyoming LLC, so hiring me is a straightforward B2B / C2C (corp-to-corp) arrangement: standard invoicing, no visa sponsorship, and no employer-of-record overhead. Buenos Aires is UTC-3, so I overlap the full US workday.
What makes you different from other engineers?
Adaptability, the ability to learn fast, and above all the capacity to never give up even with apparently impossible problems.
What roles are you looking for?
Site Reliability Engineer, Backend Software Engineering, Reverse Engineering roles, or any intellectually challenging position.
What is your English proficiency?
Professional — I have worked remotely for US companies in English for years.
Are you open to short-term contracts or consulting engagements?
No — I am looking for long-term, full-time positions.
How soon can you start?
I am available immediately — I can start as soon as we reach an agreement.
What are your salary or rate expectations?
I benchmark against the US market for senior SRE and backend engineering roles. The final number is open to negotiation once we have discussed the scope and responsibilities of the role.
