Experience
15+ years building systems that enterprise clients depend on.
Founding Engineer
SoftwareValue.ai · San Francisco, CA (Remote)
- Took a B2B AI product from zero to live enterprise pilots in under 12 months — owning the architecture, delivery cadence, and all technical decisions needed to make early deals closeable.
- Built 20+ production AI workflows covering sales coaching, competitive intelligence, and meeting analysis — directly enabling the product's revenue story with enterprise prospects.
- Embedded enterprise-grade security and compliance from the start, making it a sales accelerator rather than an afterthought when customers ran due diligence.
Founder & Senior Software Engineer
cajus.dev · Aracaju, Brazil
- Built and ran an independent consulting practice serving clients across Brazil, the US, and Australia — maintaining a 100% Job Success Score on Upwork through consistent above-expectations delivery.
- Embedded AI capabilities into ALS Global's core operations, enabling faster reporting and reducing manual processing time for one of the world's leading testing and measurement firms.
- Recovered three client systems (Sigora, Sigora Haiti, HADPRE) from complete outage back to live production, eliminating revenue loss and restoring business continuity.
- Delivered a one-click deployment tool for Vista Studios that turned a multi-hour manual setup into a minutes-long automated process — cutting onboarding cost for every new project.
Senior Software Engineer
Versionne IA · Joinville, Brazil
- Maintained zero-disruption continuity for an enterprise client portfolio through a full company restructure — preserving SLAs across B2B Sales, WMS, Fleet Management, and Salesforce integrations.
- Identified that rising client customization demand was becoming a delivery bottleneck; championed an internal low-code platform that unlocked delivery of 30+ client-specific applications.
- Owned end-to-end delivery of client-facing B2B applications — from scoping to production — acting as the primary technical accountability for each engagement.
Senior Software Engineer
Dalmark Systems Ltda · Joinville, Brazil (12 years)
- Grew into the most trusted technical resource at the company over 12 years — taking end-to-end accountability for the hardest projects and consistently delivering when the commercial stakes were highest.
- Built and operated a warehouse management system across 12+ sites processing up to 10,000 orders per day — each hour of downtime translated directly into halted operations and client financial loss.
- Led a government compliance integration (eSocial) where missed deadlines carried direct financial penalties and payroll disruption for over 1,000 employees across client organizations.
