Mid-level Full-Stack Software Engineer specializing in enterprise apps and AI integration

Redwood City, CA4y exp

“Engineer with experience scaling enterprise AI products in production, including a C3 AI deployment expanded from 2 to 4 sites across the US and Canada. Also built a GPT-4o-powered RAG assistant for plant operators, combining structured and unstructured data with human-in-the-loop safeguards and iterative evals to improve answer quality.”

“Frontend-leaning full-stack developer with hands-on experience building a proof-of-concept customer service application at Florida Blue using React/Redux Saga, Node/Express, and MongoDB. Also contributed at Yahoo via Wipro on a metrics dashboard, where their UI changes became the basis for additional team features.”

“Backend engineer focused on Java/Spring Boot microservices, workforce scheduling APIs, and event-driven systems. He uses AI tools pragmatically—roughly 25-30% assistance for scaffolding and optimization—while keeping architecture, debugging, testing, and final decisions under tight manual control. Strong on reliability and observability, with hands-on experience in Kafka-based workflows, distributed tracing, and evaluating agent frameworks like LangChain against production needs.”

Mid-level Software Developer specializing in full-stack FinTech systems

USA4y exp

“Full-stack engineer with ~2.5 years of experience spanning real-time financial systems and production AI features at BNY Mellon and KPMG. Built a trading dashboard that improved latency by 30% and an AI-assisted financial insights system that cut manual analysis by 40%, with hands-on experience in LLM/RAG architecture, evaluation, and monitoring in regulated financial environments.”

“Backend engineer who designed and evolved an AWS-based event-processing system in Python/PostgreSQL, achieving a 60% p95 latency reduction while improving reliability during traffic spikes. Led a zero-downtime migration from a monolithic Django app to FastAPI microservices using feature flags, strong testing, and cross-team coordination, with production-grade observability (Prometheus/Grafana/CloudWatch) and security (JWT/OAuth2, RBAC, Postgres RLS).”

“Robotics/AV engineer with strong ROS2 and autonomy stack integration experience, including bringing Autoware Universe up on a real Lexus autonomous vehicle platform. Also built a hierarchical reinforcement learning proof-of-concept for Boston Dynamics Spot (navigation + manipulation) and tackled sim-to-real challenges by implementing PD torque conversion for Jetson-based hardware; improved localization accuracy via GNSS+EKF fusion with a reported 28% drift reduction.”

“Backend engineer who built an async FastAPI data pipeline at GHN Career Academy to replace a manual Excel-based workflow, migrating 30k+ contact records into Airtable with validation/deduplication and best-effort GPT-based enrichment. Emphasizes reliability under messy real-world data and partial failures via structured logging, retries, and resumable processing, unlocking downstream automations (e.g., Zapier and chatbots).”

“Master’s-trained music technologist and audio editor who works across Ableton, Pro Tools, Audition, and Premiere to deliver music edits and polished mixes for video.
