“Backend-leaning full-stack engineer with 7 years of Python experience who has worked on data-heavy products in both healthcare and social media intelligence. Particularly notable for driving Elasticsearch-based search improvements on a B2B social media analytics platform and for building secure healthcare APIs using Flask/Django with OAuth, JWT, and multiple databases.”

“Backend/full-stack engineer at Qualcomm who built and operated a drift monitoring platform for 10k+ edge AI models. Stands out for combining strong TypeScript/React/Node execution with production-grade systems thinking across PostgreSQL tuning, Redis caching, ECS deployments, and Kafka-based architectural improvements that measurably improved reliability and release speed.”

“Frontend engineer with hands-on experience building data-heavy financial and climate visualization dashboards in React/TypeScript. Stands out for combining performance tuning, maintainable component architecture, and geospatial UI work, including a reported 40% reduction in initial load time on a production dashboard.”

“Frontend engineer who served as the sole developer for Walmart's locker management feature, now live in 2500+ auto care stores and credited with reducing customer check-in/checkout time by 18%. Brings hands-on experience across React/TypeScript architecture, operational dashboards, analytics, testing, and cross-functional delivery with backend and mobile teams.”

“Frontend-focused builder who developed Lushgreen, an ML-powered harvest forecasting and recommendation platform for farmers, agricultural businesses, and home gardeners. Stands out for combining React UI engineering, performance optimization, and user-centered simplification of complex ML outputs for non-technical users.”

Junior Full-Stack Engineer specializing in scalable web platforms and FinTech

San Jose, CA2y exp

“Full-stack product engineer with end-to-end ownership across React, TypeScript, backend APIs, and AI-assisted workflows. Built a scheduling management feature at Intuit that enforced complex business rules and reportedly reduced costs by about 25%, and also created a secure monorepo platform for their own jewelry business with access control and RLS from the start.”

“Customer-facing technical professional with experience supporting LLM/agentic-style workflows and complex integrated systems (APIs, backend logic, databases). Partnered with sales/customer teams at Radix Health to onboard new clients in phased prototypes, translating non-technical requirements into technical scope and implementing core product changes to tailor the appointment-booking solution for providers.”

“Frontend engineer focused on marketing and analytics products, including a real-time multi-touch attribution dashboard. Uses Next.js (SSR/ISR) with React/TypeScript and Tailwind, and emphasizes quality at scale via automated testing, CI/CD (GitHub Actions), feature-flagged staged rollouts, and Mixpanel-driven iteration. Experienced modern state management patterns (React Query + Zustand) and performance tuning (code-splitting, dynamic imports, lazy loading).”

“Full-stack engineer with experience at Vanguard, PNC, and Humana building customer-facing investment/banking flows and internal ops tools using Angular/React/TypeScript with Spring Boot microservices. Strong in shipping time-sensitive changes safely via automated testing/CI (JUnit/Mockito, Jenkins, SonarQube) and in operating event-driven microservices with Kafka (idempotency, retries, correlation IDs). Improved internal tool adoption by responding to ops/support feedback with query optimization and clearer search results.”

“Open-source JavaScript contributor focused on performance and maintainability in data visualization libraries—refactored legacy ES5 into modular ES6, added tests/docs, and delivered ~30% faster load times with positive community adoption.
