Gabriel Vs

Software Engineer with experience working across iOS applications, backend integrations, API-driven systems, and real-time infrastructure platforms. Part of the stack I’ve worked with includes Swift, UIKit, SwiftUI, PHP/Laravel, REST APIs, GraphQL, SQL, Docker, and software architecture patterns. I’ve contributed to e-commerce systems at Walmart Global Tech, backend and AI-assisted integration workflows at Cincinnati AI, and industrial monitoring platforms at Transom supporting 300,000+ real-time field signals.

My work has focused on production debugging, API integration, reliability, cross-functional delivery, and mentoring other developers.

Software Engineer – Backend Integrations at Cincinnati AI (2023-11 – Present)

• Develop PHP/Laravel integration services that connect client applications with Docker-based microservices.
• Design RESTful APIs for workspace, channel, and messaging workflows consumed by web, React, and iOS clients.
• Implement RAG-based workflows using PHP and external APIs to support document retrieval and AI-assisted product features.
• Define reusable service layers, API clients, and environment-based configuration to standardize backend integrations.
• Build client-facing functionality across React and iOS using Swift, UIKit, SwiftUI, Combine, Firebase, Core Data, and MapKit.
• Improve application stability through unit testing, structured code reviews, logging, production debugging, and data-handling optimizations.
• Built a GitHub Actions CI/CD pipeline that automated build, test, and deployment workflows, reducing manual release steps and standardizing delivery across environments.
• Mentor junior developers on API integration, Laravel, Swift, Combine, Core Data, Git workflows, and software architecture.
• Created technical documentation and training materials that reduced junior developer onboarding time by approximately 30–50%.

Senior iOS Developer – Cart & Checkout Team at Walmart Global Tech (2025-08 – 2026-08)

• Built and maintained API-driven iOS functionality across cart and checkout flows for Sam’s Club customers in the U.S. market.
• Improved reliability across critical purchase flows by resolving production issues involving date handling, user facing errors, analytics payloads, image rendering, fulfillment logic, and address validation.
• Extended GraphQL fragments and mobile data models to support new product capabilities, coordinating pull requests and cross-team validation for controlled production rollouts.
• Implemented CCM feature flags to isolate Sam’s Club U.S. specific functionality without affecting other Walmart tenants.
• Contributed to the beta rollout of a new fulfillment experience across the U.S by validating and fixing fulfillment labels, slot behavior, fee presentation, cart summary calculations, and compatibility with existing purchase flows.
• Improved Cart Summary and Thank You Page behavior through implementation, debugging, validation, and release-readiness work across cart and checkout flows.
• Improved VoiceOver and ADA-aligned accessibility across headers, loading states, carousels, grouped content, filters, snackbars, bottom sheets, image links, and focus restoration.
• Enhanced PDP and PLP product flows by resolving quantity behavior, replacement controls, bundled-item handling, multi-selection feedback, WCP component behavior, and Add to Cart issues.
• Resolved UI consistency issues involving Auto Layout, reusable components, dynamic content, banners, placeholders, spacing, and alignment across cart and checkout experiences.
• Applied MVVM-C, SOLID principles, delegation, protocol-oriented programming, reusable component patterns, and feature flags while collaborating with product, design, QA, backend, and mobile engineering teams throughout implementation and release validation.

Software / IoT Engineer at Transom (2021-06 – 2023-10)

• Designed and deployed SCADA solutions for SFO and LaGuardia airport infrastructure using ICONICS, BMS, and EMCS systems.
• Built BACnet- and OPC-connected real-time dashboards and data models supporting 300,000+ field signals.
• Integrated SQL Server with SCADA platforms for reporting, alarm processing, operational monitoring, and historical analysis.
• Implemented alarm-management and predictive-maintenance workflows to improve infrastructure visibility and operational monitoring.
• Refactored legacy C and Visual Basic systems to improve maintainability and support SCADA migration initiatives.
• Developed industrial SCADA integrations using Siemens PLC signals and diagnosed communication, data-mapping, and system-integration issues.
