Mid-Level Full-Stack Software Engineer specializing in cloud-native web applications

TX, USA4y exp

“Full-stack engineer who has owned customer-facing and internal web portals end-to-end (API, database, React UI, and deployment). Experienced designing multi-service architectures with Node/Express and Java/Spring Boot plus RabbitMQ/Kafka messaging, emphasizing contract/versioning discipline, observability, and operational tooling that measurably reduces support load and manual work.”

“Full-stack engineer with hands-on production experience building real-time customer-facing features (order tracking + push notifications) across React/React Native and Node/Spring Boot with Postgres/MySQL. Demonstrates strong reliability patterns (transactional outbox, background workers, idempotent webhook ingestion) and has deployed/operated systems on AWS (ECS/Fargate/ALB, CloudWatch, CodePipeline) with structured observability and environment separation.”

“Founding engineer at Novum AI building a real-time call analytics/suggestion backend (transcription + sentiment/tone + context retrieval) using a serverless architecture. Drove major latency improvements (about 4s down to sub-1.5s) and has practical experience hardening production APIs (FastAPI/Pydantic, auth with Cognito/Redis) and payment systems (Stripe) by surfacing overlooked subscription and multi-tenant billing edge cases.”

“Built and shipped production LLM agents including an AI patient appointment assistant for Kyron Medical that automated specialist matching and end-to-end booking with email/SMS confirmations and a voice mode. Strong focus on production reliability (double-booking prevention with DB constraints and pre-write checks), deterministic multi-step orchestration with LangGraph, and rigorous monitoring/evaluation using LangSmith trace replay for prompt regression testing.”

“Gameplay engineer with hands-on ownership of a computer-vision body-tracking system that powered Dance Break, a full-body dance game shipped across Windows, Mac, iOS, and Android and used at large live events like EDC Las Vegas and Alibaba CoCreate. Particularly strong in performance-sensitive Unity systems, cross-platform optimization, and multiplayer architecture decisions, with experience spanning mobile, VR, and deterministic networking.”

Mid-level Software Engineer specializing in full-stack systems and AI applications

Tempe, AZ3y exp

“Software engineer with 3 years at Gap Inc. who led a major modernization from monolith/legacy frontend to a React and Spring Boot microservices architecture, delivering 25% cost savings, 30% faster releases, and 50% performance gains. Also built a 0→1 startup product, MealShare AI, using managed cloud services to rapidly launch a real-time food redistribution platform.”

“Unity gameplay engineer with 10 years in game development who has shipped dozens of mobile titles and built high-impact shared systems, including a custom touch framework still used across 100+ ABC Mouse mini games. At Battle Creek Games, they paired strong Unity engineering with AI-assisted workflow automation, cutting a 4-day car setup process to 30 minutes and delivering a partnership update that drove over $1M in a single weekend.”

“Data and backend-focused engineer with hands-on experience spanning GenAI applications, production telemetry systems, and large-scale ETL pipelines. They combine modern AI stack work (React, FastAPI, LangChain, ChromaDB) with measurable production impact, including 90% lower DB insertion latency, 50% higher ETL throughput, and 99.9% data quality in distributed environments.”

“Unity game developer who built a quest system for a Hearthstone-like card game where completing quests upgrades and expands card abilities, increasing build flexibility and improving player experience. Has general networking experience via socket servers and HTTP requests, and uses Cursor/ChatGPT to accelerate animation work while keeping core logic and code quality under manual control.”
