About

My work spans enterprise integration strategy, cloud modernization, and platform engineering across regulated and large-scale environments. I contribute to the professional community through research, peer review, and speaking engagements, with a focus on advancing scalable, interoperable enterprise systems.

Professional Experience

Docusign
Docusign Lead Software Engineer · 2022 – Present

At Docusign, I led and contributed to enterprise integration initiatives connecting eSignature and CLM with critical business platforms including Salesforce, SAP Ariba, Microsoft SharePoint, and Microsoft Outlook. I helped architect and implement embedded contract lifecycle workflows—enabling in-place contract generation, routing, approval, and signing directly within enterprise systems. These integrations streamlined cross-functional operations and advanced scalable, API-driven interoperability across complex SaaS ecosystems.

Salesforce
Salesforce Senior Member of Technical Staff · 2018 – 2022

At Salesforce Marketing Cloud, I contributed to the architecture and engineering of a hybrid, multi-cloud data ingestion platform powering large-scale digital marketing automation and analytics. I designed and built scalable, highly available services to process high-volume flat-file and API-based integrations across FTP, AWS, and Azure. These systems enabled reliable, multi-source data pipelines that supported real-time campaign execution and enterprise-grade marketing intelligence.

Signature Projects

Scalable APIs for Data Ingestion

Outcome: Critical data-ingestion APIs improved by 70%+ in performance—faster, more reliable pipelines that cut delays and raised throughput for enterprise marketing automation and analytics.

What I built: On Salesforce Marketing Cloud, hybrid engineering on the data-ingestion platform—flat-file imports and APIs that feed digital marketing automation and analytics. Built scalable, highly available services in public and private clouds; designed systems to import large volumes from multiple sources (FTP, AWS, Azure).

Tech: REST APIs, cloud-native services, observability (e.g. Splunk, Azure), high-volume data pipelines.

Docusign Enterprise Integrations

Outcome: Teams prepare, sign, and manage agreements inside CRM and procurement tools—integrations used across the customer base, with fewer context switches and stronger automation and interoperability.

What I built: Initiatives to integrate Docusign eSignature and CLM with enterprise systems: Salesforce, SAP Ariba, Microsoft SharePoint, and eSignature for Microsoft Outlook. Contributed to design and implementation of integrations that support contract generation, routing, and signing in place.

Tech: eSignature & CLM APIs, event-driven workflows, Azure Service Bus, C# / .NET.

Event-Driven Agreement Orchestration

Outcome: Enabled real-time, contextual agreement execution by replacing brittle integrations with event-driven workflow orchestration. Users generate, route, and track agreements directly within their primary application (e.g., Salesforce) at the moment a business event occurs.

What I built: Designed an event-driven pattern where Maestro workflows emit lifecycle events that automatically trigger Docusign envelopes inside Embedded Navigator. This decouples workflow logic from envelope execution and replaces manual or point-to-point integrations with scalable, loosely coupled orchestration.

Tech: Event-driven architecture, Kafka, Service bus, distributed integration patterns.
