Wesley Fuchter
Wesley Fuchter
Modus Create, Sao Ludgero, Brazil
Wesley Fuchter is Director of Software Engineering at Modus Create, where he spends his time turning AI coding tool experiments into organization-wide practice. After leading a structured A/B experiment that demonstrated a 40% reduction in development time, his focus shifted to the harder challenge: getting a full engineering team to actually leverage agentic coding. His team built the knowledge-sharing systems, workshops, and practical resource libraries that are driving the shift. With 14+ years in cloud architecture, enterprise modernization, and engineering leadership across healthcare, fintech, and Fortune 100 organizations, Wesley brings a practitioner's perspective, including what didn't work. He holds the AWS Solutions Architect Professional certification and has previously spoken at worldwide tech conferences.
