roles

→Shipped fulfillment + payment features for a 67k-artist platform processing $11M+ across 85k orders.
→Built the Stream Tracking system on a Postgres trigger across 10.6k campaigns and 26.5M tracked streams.
→Pitched and built a buy-one-get-one free-song promo end-to-end that ran $182k across 988 orders in 3 weeks.
→Kept unfilled bonus orders out of both admin queues via a PostgREST computed-column SQL function.
→Fixed the root cause that broke site-wide SSR (FCP 3.1s → 1.4s) and lifted a checkout from PSI 12 → 41.
→Rolled out deny-by-default RLS across ~51 production tables, verified by 287 pgTAP privilege tests.

→Built a cloth-folding RL env in MuJoCo + Gymnasium with a 141-dim observation (cloth, robot, task).
→Shaped a dense corner-to-goal distance reward plus a sparse +10 success bonus at fold score ≥ 0.85.
→Defined a 14-dim continuous action space for two 5-DOF SO101 arms, actuated via Jacobian least-squares IK.
→Trained PPO (Stable-Baselines3 MlpPolicy) on a flattened Dict→Box observation for 200k steps.
→Faked flat-cloth grasping via a runtime MuJoCo WELD constraint and fixed a NaN contact blow-up on touch.

→Built a NiceGUI + Plotly dashboard streaming 50 Hz motor-current and joint-angle telemetry from an ESP32.
→Wrote a Pandas pipeline that flattens nested JSON telemetry into analysis-ready CSVs.
