Hey there! I’m Eder, a tech-driven Fraud Prevention & Risk Analyst with a solid 7-year background running high-volume banking operations. Right now, I’m wrapping up my Tech degree (ADS) and combining that analytical mindset with digital solutions, data integrity, and global localization services. My corporate journey taught me to catch anomalies and patterns that most people miss—whether that’s auditing complex transactional logs, securing enterprise frameworks against prompt injection, or localizing technical content between English, Spanish, French, and Portuguese. I use tools like Falcon, Feedzai, and Splunk, but more than just tools, I care about actual data accuracy and team trust. I’m highly adaptive, responsive, and genuinely looking to build solid freelance partnerships where we can solve problems and scale together. Let’s connect and get to work!…

    paper Technical Localization & Tech Risk Architecture

    Project Overview

    A comprehensive technical framework combining elite translation capabilities with digital system integrity. This project focused on adapting complex corporate documentation and e-commerce infrastructure while auditing deployment risks.

    1. Technical Translation & Localization

    • Challenge: Migrating highly technical structures from English into natural, fluent Portuguese (Brazil) and Spanish without losing context or regulatory accuracy.
    • Scope: Focused on fintech terminologies, API integration guides, and payment gateway documentation (including digital wallet architectures like Apple Pay and Samsung Pay).
    • Result: 100% natural flow, keeping the language engaging for users while preserving corporate compliance standards.

    2. AI Safety & Tech Risk Assessment

    • Challenge: Auditing enterprise LLM deployments against adversarial interactions.
    • Mitigation Strategy: Applied advanced data pattern recognition to block prompt injection vulnerabilities and secure core operational boundaries. Implemented behavioral monitoring frameworks derived from high-volume banking security models (Falcon/Feedzai concepts) to identify anomalous bot activities.
    • Result: Enhanced database security, drastic reduction in system manipulation vectors, and audit-ready data flows.

    Developed by Eder Dias — Fusing 7+ years of corporate banking precision with modern Systems Development (ADS) architecture.
