Senior Product Manager — Developer Platforms & APIs | Agentic Workflows

Flagstaff, AZ • cgabaldon@gmail.com • linkedin.com/in/carlosgabaldon • github.com/CarlosGabaldon

SUMMARY

Product and platform leader with 20+ years building the core systems other engineers build on. Today I lead Doximity’s Core Stack Messaging platform — the Kafka-based eventing, A/B testing, and delivery services every app team depends on — owning the roadmap and API surface so product teams ship clinician value instead of rebuilding primitives. Deep in developer tools and workflows, event-driven APIs at scale, and schema governance. Now also building a production agentic AI platform which gives me hands-on, current perspective on AI agents as first-class API consumers alongside developers. I translate developer needs into roadmap, drive metrics-based decisions, and ship across distributed, asynchronous teams.

CORE STRENGTHS

• Developer Productivity & Internal Platform Strategy
• API & SDK Design at Scale — event-driven / pub-sub, schema governance, versioning
• Agentic Workflows & AI Agents as First-Class API Consumers
• Roadmap Ownership, Product Vision & Prioritization
• Metrics-based Decision-Making & A/B Experimentation
• Cross-functional & Executive Stakeholder Partnership
• Distributed / Asynchronous Global Teams
• Reliability, Performance & Developer Experience (DX)

EXPERIENCE

Engineering Manager & Tech Lead — Core Platform | Doximity May 2019 – Present

• Lead the internal developer platform powering every Doximity app team. Portfolio: Dox Messaging (Kafka pub/sub), Spectrum (A/B testing), EDA (email delivery), DUT (bulk data). Doximity is the largest professional network for U.S. clinicians (NYSE: DOCS).
• Set product vision and roadmap for a portfolio of developer-facing platform products under an explicit charter: identify, build, and support the core systems so app engineers focus on delivering clinician value instead of building primitives.
• Own an event-driven API surface at scale — Kafka producers/consumers, Avro-encoded messages, and a Confluent Schema Registry with enforced backward/forward compatibility — enabling safe schema evolution across dozens of applications without breaking downstream consumers.
• Shipped a consistent, multi-language client surface (Ruby gems, Python clients, iOS SDK) so the same platform capabilities are consumed uniformly across web, backend services, and mobile.
• Operate a company-wide split-testing (A/B) platform that lets product teams make metrics-based decisions and hold treatments consistent across desktop and mobile.
• Drive reliability and performance through instrumentation, consumer autoscaling signals, dead-letter strategies, and throughput tuning — with documented runbooks and error-handling guidance for consuming teams.
• Partner cross-functionally and asynchronously across a distributed org: run cross-team tech syncs, communicate technical direction to stakeholders, spike large problems for feasibility, and write the technical proposals that guide implementation.

VP of Engineering | BoldLeads — B2B SaaS Mar 2017 – Mar 2019

• Built a B2B SaaS engineering organization and platform from the ground up across U.S. and India; introduced Git, CI/CD, code review, and a product-management culture that drove predictable delivery.

Associate Director / Product Owner — Bespoke Offers | Barclaycard Feb 2013 – Nov 2015

• Product Owner, Scrum Master, and Tech Lead for the Bespoke Offers product; owned requirements, prototypes, and acceptance criteria across distributed U.S. and European teams.

Director of Product Development | GoDaddy Mar 2010 – Jul 2012

• Directed hosting product development and infrastructure provisioning serving 4M+ customers; led rollout of product offerings to a new overseas data center — product ownership at large scale.

Manager, Software Engineering | Apollo Group (University of Phoenix) Aug 2005 – Mar 2010

• Lead architect for a large-scale Web Content Management integration spanning multiple business units; designed cross-organizational platform services and integration APIs.

Earlier Experience 2000 – 2005

• Senior Software Engineer, JDA Software (2003–2005) — subscription-driven retail / supply-chain product (Portfolio Registry™); led a .NET / SQL Server initiative with Microsoft.
• Software Engineer, Keane Inc. (2002–2003) — built a standardized web-service (API) interface to major Global Distribution Systems for American Express Corporate Travel.
