Mid-Level Full-Stack Software Developer specializing in modern web apps

San Francisco, CA5y exp

“Product-focused full-stack builder who has shipped and operated multiple production apps from scratch, including an e-commerce bakery delivery scheduler (with concurrency controls and timezone handling) and a real-time passenger music-request system for Lyft rides that hit and resolved YouTube API rate-limit scaling issues via debouncing and caching. Strong in React+TypeScript and Node.js/TypeScript backends, with solid PostgreSQL/PostGIS data modeling and performance tuning.”

“Hands-on engineer who has taken an LSTM Bitcoin forecasting model from notebook to a production-grade, monitored API (Docker/Gunicorn/Nginx, Prometheus/Grafana, blue-green rollback) delivering 99.9% availability and ~110–120ms p95 latency. Also built an RFID self-checkout prototype spanning Raspberry Pi + firmware + networking, using deep instrumentation to eliminate double-charges/timeouts (<0.1%) and reduce checkout time ~20% through idempotency, debounce logic, and hardware fixes.”

“NYC government job developer (DYCD) doing high-volume outbound business outreach across the five boroughs to build employer partnerships supporting workforce development. Runs predominantly cold-lead motions using CRM and Department of Labor databases, prioritizing prospects via LinkedIn/job-posting signals (e.g., CPA firms/consultancies). Prefers phone and in-person outreach for higher engagement and uses AI/automation mainly for internal correspondence and admin/data entry.”

“Backend/ML engineer with deep fintech and marketplace experience: built a real-time financial analytics + algorithmic trading platform (Python/Postgres/Kafka/Redis) and drove major DB performance wins (10x faster analytics; sub-10ms response consistency). Also shipped an end-to-end ML recruitment matching platform (scraping/ETL/modeling/Django deployment) with reported 92% matching accuracy, and emphasizes production reliability via monitoring, blue-green deploys, and robust workflow error handling.”

“QA automation engineer who owned an end-to-end Selenium/Java suite redesign (POM + REST Assured + Jenkins), boosting coverage from ~30% to ~70% and shrinking regression from days to hours. Known for fast, high-signal debugging and bug reports (API traces/logs, token/session expiry evidence) and for catching high-impact issues like intermittent payment failures and authentication/session defects before production.”

“Robotics-focused engineer with hands-on experience building a lab robotic arm, combining software engineering with circuit design and hardware integration (DC motors, Raspberry Pi, gamepad control). Has worked on mapping (GMapping) debugging and implemented MQTT-based communication between Raspberry Pi and ESP32, plus used MATLAB/Simulink to simulate STM32 behavior for system-level testing.”

“Confidentiality-focused advisor/consultant specializing in decision and risk analysis, strategic communication, conflict/crisis management, and reputation/trust building for founders and executive teams. Emphasizes proactive prevention/mitigation and uses interviews plus written/verbal advisory reports to shift leadership behavior and reduce preventable risks.”
