Junior Full-Stack Engineer specializing in FinTech systems

Austin, TX1y exp

“Full-stack engineer with deep experience in high-stakes integrations: owned end-to-end fintech payment notification/installment tracking at an early-stage startup (FastAPI/React/AWS), including multi-environment routing for live banking partners and reliability patterns like idempotency and retries. Also built a Coachella partner ticketing platform (React/TS/Node/Postgres) with strong concurrency controls and zero-downtime migrations, and previously delivered media-asset ETL/file-sharing automation at Sony Pictures using Frame.io with checksum-verified transfers.”

“JavaScript/React performance-focused engineer who contributed upstream to an open-source virtualization/pagination library, fixing overlapping-fetch race conditions and introducing prefetch/deduping patterns that cut load times from ~3s to <900ms and reduced render thrash ~35%. Also built healthcare automation systems (clinical summary and claims triage), including a FastAPI + RAG pipeline that retrieved CPT/ICD evidence, improving decision accuracy from 67% to 86% and reducing turnaround time by 40%.”

“Full-stack/backend-heavy engineer with experience across real-time product systems and high-scale financial analytics, citing work on Flashcode, Netflix, and Bank of America via TCS. Particularly strong in Kafka-based event-driven architecture, streaming pipelines, and production performance tuning, with concrete wins including a 15% latency reduction and scaling reliability from 30k to 50k+ concurrent events.”

“Backend engineer who built the core backend for Air Kitchens’ discovery/booking platform on AWS (Node + Python, DynamoDB, SQS/Lambda), optimizing for fast user-facing APIs and scalable async workflows. Introduced an AI matching service with a deterministic pre-filter + LLM ranking approach to balance latency vs quality, and has hands-on experience with production security (JWT/RBAC/RLS), CI/CD, and blue-green, staged migrations from Django to modular services.”

“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.”
