Job Description

Hey everyone, I'm a backend engineer from Brazil with professional experience building robust, secure, and production-ready APIs — mainly in PHP, Golang, and Java. I'm currently looking for a **remote opportunity (USD-based)** where I can contribute to real-world systems, especially in fintech, SaaS, or API-driven platforms. I'm also **flexible with compensation**, especially for my first international opportunity, and open to discussing a fair rate that works for both sides. **What I do best:** * Design and build REST APIs with clean architecture (Controllers / Services / Models) * Authentication & security (JWT, HMAC, middleware pipelines) * Integrations with external systems (KYC, payments, webhooks, third-party APIs) * Database modeling (PostgreSQL, MySQL, SQLite — including JSONB and audit trails) * Multi-tenant systems (multi-company logic, access control) * Background jobs / CLI processes (automation, controlled execution) **Tech stack:** * Languages: PHP (main), Golang, Java * Backend: REST APIs, authentication flows, system integrations * Databases: PostgreSQL, MySQL, SQLite * Tools: Docker, Linux, Git * Frontend (basic): React, Svelte, Vue **Recent experience:** * Built a backend for a **tokenization & financial platform**, including wallet systems, orderbook, and payment integrations * Worked with **KYC providers, payment gateways, and secure mTLS communication** * Developed multi-tenant SaaS systems with authentication and reporting * Experience with real-world production environments and system design **How I work:** I’m not just a "task executor" — I focus on understanding the problem, designing the solution properly, and delivering something reliable and scalable. If you’re looking for a backend developer who can **own features end-to-end and integrate complex systems**, feel free to DM me. Thanks!
