Eduardo Raghi Rashid Fernandes

Build Go microservices for the financial infrastructure platform. Started in financial operations support—reconciling and fixing inconsistencies between orders and financial transactions—then moved to a Go microservices team focused on Pix outgoing payment and settlement flows integrated with SPI, Pix key resolution and participant identification (DICT), Central Bank regulatory event reporting, stored-value products with yield and IOF calculations, withdrawals and payments (money movement between accounts), and account base migration between payment institutions including transfer/regularization and downstream adaptations. Work emphasizes data consistency and integrity, traceability of operations, and robust handling of failures in external integrations and domain rules with no room for approximation.

Backend on a tax document and process platform with heavy integration work across dozens of city governments. Implemented issuance flows by building XML, sending requests, parsing responses, updating statuses, and handling rejections. Adapted communication for each municipality’s particularities, and supported asynchronous processing through webhooks and polling. Used RPA to automate retrieval of tax payment slips, reducing recurring manual work. Contributed to implementing a new technical specification (Nota Técnica) introduced by Brazil’s tax reform by updating data capture (Selective Tax, IBS, CBS, ISPB), XML structure, and submission to city governments.

Worked across multiple products in a software house environment, adapting quickly to different legacy codebases and client contexts. Main contribution in a Vehicle Protection SaaS: vehicle registration, contracts, monthly fees, deductibles, billing, boleto generation via a payment provider, and FIPE table vehicle data lookup. Also performed maintenance and bug fixes on a legacy PHP 7.2 radio advertising system, and contributed to a Spanish company server landing page.
