Herbert Smith — Resume

Staff-track platform engineer with experience owning enterprise APIs, standardizing contracts across UI → API → DB layers, building automation that removes months of manual effort, and designing reliable developer-facing systems teams can adopt without friction. Current proof spans public OSS, AI-assisted workflow design, hosted platform surfaces, and reusable candidate/application-kit systems. Strong fit for product, platform, and enterprise engineering work centered on reusable services, observability-aware design, API integration, scalable system ownership, and cross-team alignment.

Experience

Citigroup Inc. — Apps Dev Tech Lead Analyst (VP)

Dallas, TX · Dec 2023 – Dec 2025

Owned 80+ internal REST endpoints and built 72+ from scratch for a subscription automation platform, delivering reusable workflows across subscriptions, schedules, deliveries, and notifications that replaced manual approval paths for internal teams.
Spearheaded UI → API → DB contract alignment by standardizing auth guards, HTTP clients, REST endpoints, and request/response models, enabling teams to scale independently with easier onboarding, fewer regressions, cleaner tests, and less cross-team confusion.
Architected reusable Spring Boot patterns across controllers, services, repositories, interceptors, mapping, logging, and test layers; built new platform modules when teams needed capabilities instead of encouraging one-off service-level hacks.
Integrated health checks, error logging, and auditability into a custom request/response framework, improving observability, production traceability, and failure isolation across OpenShift, Kafka-connected monitoring, Redis-backed flows, and Oracle-driven operations.

JPMorgan Chase & Co. — Android Developer / Software Engineer

Plano, TX / Global · Oct 2021 – Apr 2023

Supported a flagship enterprise Android platform through modernization from Java to Kotlin, sustained delivery through major adoption growth, and helped operate a high-impact application used across a large internal user base.
Challenged a default TalkBack implementation and designed a modular Text-To-Speech accessibility architecture tied to lifecycle events, logs, warnings, errors, and HTTP state, creating a more deterministic and extensible experience for visually impaired users.
Used Android Profiler and debugging tools to improve screen responsiveness, concurrency behavior, and network-aware performance; also served as an on-shore technical anchor by onboarding newer developers and helping guide delivery during periods of shifting team context.
Expanded automated regression coverage by 950% with JUnit, Mockito, Robolectric, and Espresso, strengthening release confidence and reducing manual QA risk for a rapidly growing enterprise Android platform.
Built and performance-optimized a proprietary MariaDB-to-Oracle SQL translation tool that converted millions of lines of SQL in 12 seconds, removing a migration effort estimated at roughly four months for a seven-engineer team.

Open Source / AI Product Systems

Public OSS, Candidate Tooling & Hosted Platform Proof

Current

Opened a public Microsoft VS Code PR (#313453) improving triggered-breakpoint debugger UX; built and validated Code - OSS locally, signed the Microsoft CLA, and handled reviewer feedback while preserving edge-case behavior.
Built Soarsoft-hosted candidate and application-kit systems as live proof-in-progress: static recruiter artifacts, role-alignment kits, manifests, validation scripts, and source-of-truth workspace data that turn repeated positioning work into reusable infrastructure.
Designed Signal Forge as a custom GPT / AI workflow system for source-first SVG asset generation, prompt protocols, tool-routing guardrails, human review, failure-mode analysis, technical reporting, and governed runtime promotion.
Continued evolving a Kotlin/Gradle/KSP platform for typed HTML and SPA generation, using the hosted candidate surfaces as an inspectable reference implementation rather than a private demo.
