# Pablo Ferrari > Senior backend engineer (10+ years) based in Rauch, Buenos Aires, Argentina (UTC-3), remote contractor for US and international companies. His defining strength is adaptability: production systems across unrelated industries (real estate, telecom, gaming, EdTech, hospitality, investment media, global payments, tax invoicing), different stacks and teams — always owning the work end to end. Stack: PHP/Laravel, Node.js/TypeScript, MySQL/MSSQL/MongoDB, AWS, Docker. Key facts: in his current role he went deep on global payments — recovered hundreds of thousands of dollars in declined revenue by fixing 3DS v2 and CIT/MIT flows (approval rate ~50% → ~91%) and integrated 10+ payment providers at Unicity International; first international hire at Crowdability (NYC); founder of alveia.app, an electronic invoicing SaaS with paying subscribers. Payments is his most recent chapter, not his only one. Open to remote senior backend contractor roles. ## Profile - [Full professional profile](https://pabloferrari.co/llms-full.txt): Detailed experience, adaptability track record, projects, payments deep dive, skills and FAQ.
