Founder
Gabe Fernandez founded CodeHarmonic in 2025 after 13 years at USAA, where he was tech lead and solution architect for an eligibility platform handling 1M+ requests a day. He holds 70 U.S. patents and an M.S. in Computer Science focused on deep learning.
He co-founded and built Receptiva, a bilingual AI phone receptionist for law firms that has been live since June 2026, and leads engineering for a medical case-management platform that handles patient imaging and physician reports.
CodeHarmonic is also the studio behind two App Store products — BookMatcher and Recall Beacon. You can see Gabe’s full background and project portfolio at gabecfernandez.com.

How we work
- Fixed-scope sprints or a monthly retainer. Sprints have a defined outcome and timeline; retainers give you ongoing senior engineering capacity.
- AI-native process. Agentic coding, test-first changes, and human-reviewed pull requests. You own the code.
- Production first. Evals, monitoring, Terraform, and CI/CD are part of the build, not a later phase.
- Voice stack chosen per use case. Realtime voice models and telephony, picked for latency, voice quality, and cost.
