Select Projects
Apteon
- Conceived, architected, and built a system that elicits expert judgment through Socratic questioning and compiles it into reviewed, typed, citable, graph-linked knowledge objects for application to unseen material.
- Built a three-condition evaluation harness; structured knowledge extraction measurably outperformed both raw context stuffing and an unaided foundation model on an unseen legal-drafting task.
ABS Locator
- Built and self-host a tool that finds which nearby store has a specific product in stock on Utah's state liquor-monopoly site, which has no such search of its own.
- Built a resilient data ingest pipeline with parallel and resumable execution, self-imposed rate limiting, and a pytest suite validated against an in-memory mock database.
- Shipped three independently deployed services on Terraform-provisioned AWS infrastructure with scheduled scraping and geo-sorted search — running unmonetized since 2018.
Experience
HashiCorp (an IBM company)
Senior Staff Resident Architect
Staff Resident Solutions Architect
Promoted to Senior Staff after designing and leading an enterprise-wide delivery transformation.
- Designed and now lead 10 Days to the Cloud for a top-5 US financial-services enterprise, cutting the secure cloud-delivery path from 6–12 months to 10 days, with 4 pilot workloads shipping.
- Own its platform core end to end — HashiCorp-based self-service infrastructure deployment, policy-as-code “fastpass” approvals, and Vault-as-a-Service — across engineering, deployment, operations, support, and on/offboarding automation.
- Developed it on Terraform Enterprise, Sentinel policy as code, and Vault dynamic secrets across AWS, Azure, and GCP: account setup cut from 6 weeks to 10 minutes, 100+ reusable Terraform modules, and Vault-as-a-Service now extending to more clouds, geographies, and the mainframe estate.
- Established 40+ Wiz-integrated policy-as-code guardrails that pre-approve conforming deployments, plus AI tooling generating policy from security-control PDFs; authored the charter, RACI, and operating model adopted across four VP organizations.
- Lead a matrixed team of 4–6 consultants and engineers across security, platform, and application-enablement workstreams, translating executive priorities and cross-team dependencies into sequenced delivery.
- Advised 4 enterprise accounts as Staff Resident Solutions Architect, including a top-5 global bank, growing portfolio consumption 50% above baseline and cutting churn 50% below baseline.
- For that bank, authored the target-state system design, HLD, and LLD for an enterprise secrets platform covering 580K+ service accounts — least-privilege persona model, LDAP/AppRole/Kubernetes auth, and automated onboarding.
- Planned its in-place modernization to integrated storage and multi-region clusters, sequenced across five environments via DR replication with fully scripted, no-manual-step execution.
DMI
DevOps Architect
- Created a reusable cross-client DevOps delivery model adopted across 3 client engagements, cutting client onboarding from 3 weeks to 3 hours.
- Researched, designed, and documented DevOps architecture and production hosting for financial-services and government clients, then productized that approach as a standard offering across the client portfolio.
- Designed cloud-native CI/CD and hosting architectures; trained and mentored a team of 5 DevOps engineers and served as the client-facing technical voice on architecture and delivery decisions.
Technical Architect
- Designed and built front-end applications for enterprise and government clients on a fast-paced Agile cycle, owning architecture decisions with high independence.
- Provided technical leadership on application and systems architecture across concurrent client engagements, and mentored junior engineers.
Oracle
Senior Software Engineer, Oracle Cloud Commerce
- Engineered commerce-merchandising capabilities for enterprise customers, contributing product and systems judgment to secure, scalable application delivery.
Gaia Interactive
Senior Software Engineer / Game Designer
- Designed social and mobile game systems with relationship-driven mechanics, including a peer-voted art competition that increased day-1 retention 40%.
Woot Ding
Founder and Software Engineer
- Built and shipped independent Facebook games solo, peaking at 40K monthly active users.
