Experience
Software Engineer Intern
WiBotic Inc. · Seattle, WA
CurrentAug 2026 – Present
- Architected an agent-in-the-loop evaluator: a local Qwen model turns freeform objectives into typed specs via tool schemas, with Pydantic validation, one error-fed retry, and escalation to the engineer — reaching 97% valid specs on the first pass.
- Designed capped orchestrator-workers execution for 5 concurrent XFEMM simulations, with a code-based pass/fail check so the model proposes and code decides.
- Developed a Python GUI that automates coil design and FEMM simulation with SQLite result caching, cutting iteration time 75%+.
- Delivered a custom Buildroot Linux appliance bridging a lunar lander's battery charger (RS-422/SLIP) to the office network, exposing telemetry over HTTP, in 3 weeks on an unfamiliar stack.

PastOct 2025 – Mar 2026
- Led a team of 5 to ship an agentic wallet that recommends the best card in real time, reaching 200+ beta users.
- Cut recommendation latency from about 500ms to 160ms across 50 cards with a React Native app using geofencing and a client-side cache.
- Replaced manual data collection with a scraping + LLM extraction pipeline across 40+ bank sites, with schema validation and a review queue for failures, reaching 92% accuracy on 50+ samples.

Projects
A few things I've built recently. Each card links straight to the live project or repo.
May 2026
TaxBuddy
An agent-loop architecture for autonomous tax filing, guarded end-to-end.
- Agent loop for autonomous tax filing (retrieval, computation, PDF generation tools) bounded by max turns, a cost cap, and a forced structured final tool.
- Pydantic guardrails on model output, with code-side approval before any irreversible submission.
- Cut per-document inference cost about 97% with a multi-agent extraction pipeline, reaching 99% field accuracy on 100+ real documents.

Voice AI Agent
Sep 2026
Voice AI Agent
A real-time 311 voice agent where the model picks the route and code executes it.
- Real-time 311 voice pipeline with a classifier-only router — the model picks the route, code executes it, unknowns go to a human — with triage latency under 650ms.
- Hybrid retrieval (pgvector + BM25, RRF) where code verifies every cited chunk ID and flags fabricated citations.
- Event-driven backend handling 10,000 concurrent queries at 94% autonomous resolution.

Drawing Reviewer
An AI pre-production analysis platform that automates engineering drawing inspections.
- Two-phase analysis: classifies the drawing type to scope applicable review categories, then runs structured checklists per category — skipping inapplicable ones to cut false positives.
- Vision-based intake accepts PNG, JPG, and PDF as base64, batching up to 10 files per submission with MIME-type validation.
- Produces scored reports (0–100 per category) with severity-ranked issues and a REVISE AND RESUBMIT verdict driven by critical defect counts.

AirTag-Like BLE Tracker
A dual-ESP32 asset tracker running FreeRTOS, with BLE, IMU motion detection, and RFID access control.
- Designed a dual-ESP32 system with FreeRTOS tasks, queues, and semaphores achieving 95% real-time movement update reliability.
- Integrated BLE 5.0 advertisement, MPU6050 IMU motion detection, and RFID-based access control on a single ESP32 platform.

Line-Following Robot
A PID-controlled line follower on a custom 2-layer PCB designed in KiCAD.
- Designed and tuned a PID control loop using 5 photoresistors for line detection, achieving 95% path accuracy at 0.5 m/s on a standard test track.
- Designed a 2-layer PCB in KiCAD consolidating motor drivers, sensors, and microcontroller into a 20cm × 10cm footprint, eliminating breadboard prototyping entirely.
