Andreus Timm

I'm Andreus Timm, an AI Software Architect, Senior Software Engineer, and Tech Lead based in São Paulo, Brazil. I have 20+ years of experience in software development and have spent the last five years working remotely as part of international engineering teams, primarily for U.S. companies, since 2021.

My background spans AI and machine learning, data engineering, backend and full stack development, distributed systems, cloud infrastructure, and technical leadership. I work across the software lifecycle: designing architecture, writing production code, reviewing implementations, improving reliability, and mentoring engineers in multicultural teams.

INTERNATIONAL EXPERIENCE

At The Hackett Group, I architected and led the development of LLM-powered data-strategy and analytics platforms, combining Claude and OpenAI with data profiling, semantic models, and multi-tenant applications. I also established Spec-Driven Development practices with AI coding agents and extensive automated quality gates.

At Quilt Software / POS Nation, I architected and built a cross-platform desktop application for a cloud POS serving 3,000+ retailers. At MPC, I built multi-tenant user management and distributed promotion-delivery systems for a platform deployed in 20,000+ locations across 30 countries.

My experience also includes backend game engineering for SciPlay through Amber Studio, full stack development for ADT Solar, and engineering on Bankrate's mortgage marketplace at Red Ventures through BairesDev. I have led enterprise legacy modernization at Regal Rexnord and mentored 10+ engineering teams at BairesDev.
