R0 SystemsFounder & CEOJun 2024 - PresentI founded R0 to replace chlorine on produce wash lines with plasma-activated water generated on demand from air, water, and electricity, and bootstrapped it to 6-figure revenue.I designed every part of the machine, including the patent-pending plasma reactor and microbubble generator, Venturi gas transfer at 22 L/min, drive electronics, and an STM32 hard real-time dosing loop in C/C++. The full system runs on 44 watts.In validation, R0 outperformed chlorine on disinfection without chlorate or perchlorate residue, kept produce fresh 3x longer, and ran cheaper than incumbent chemistry. Three peer-reviewed papers, two pending patents, and independent national food-safety laboratory studies back the work.OpenTradeMachine Learning EngineerJun 2026 - Sep 2026I joined as OpenTrade's first ML hire and owned the decision path from live market data to grounded LLM-generated trade cards to the personalized ranking determining what each user saw.Replaced hand-tuned feed ordering with a learned ranking model built from user interaction, content, recency, and market-context signals and evaluated releases through offline replay and product behavior.Built a factual-accuracy and regression harness for generated financial content, checking grounding against live market data, numerical consistency, temporal validity, unsupported claims, and structured-output compliance across model and prompt releases.Closed the model-data loop by turning impressions and downstream user behavior into evaluation and training signals, with pre-registered launch hypotheses, primary metrics, and guardrails before shipping to production.Built backend and serverless API routes serving model outputs, integrated external market-data providers, and owned testing, deployment, and CI for a product that grew from launch to roughly 150,000 monthly users in two months.Sensors, Energy, and Automation LaboratoryResearch AssociateMar 2025 - Nov 2025Engineered a real-time PPG drowsiness wearable from sensor to signal pipeline, including a transimpedance front end, fourth-order Butterworth filtering, 100 Hz 12-bit acquisition, and adaptive noise cancellation rejecting 95% of motion artifact.Built a PZT-array acoustic-emission system for U.S. Navy hull-integrity monitoring, using charge amplification, 10 kHz acquisition, and a real-time 512-point FFT pipeline to separate impacts from fatigue-crack signatures.Took sensing systems through analog design, prototype bring-up, embedded acquisition, signal processing, bench characterization, and failure analysis.Authored the sensing architecture, signal-processing methodology, and validation sections of two funded proposals across a seven-person research team.CSIR-National Institute for Interdisciplinary Science and TechnologyResearch AssociateJun 2024 - Mar 2025Researched dye-sensitized and perovskite photovoltaics within CSIR-NIIST's indoor-light energy-harvesting program, whose dye-sensitized-cell work later reached a 40% indoor-light conversion-efficiency record.Fabricated complete solar cells using FTO substrates, TiO2 photoanodes, thermal processing, ruthenium sensitizers, electrolytes, counter electrodes, and sealed device assemblies.Ran the full optoelectronic and structural characterization stack, including J-V curves, IPCE, photoinduced absorption spectroscopy, and XRD with Scherrer crystallite-size analysis.Connected spectral response, charge-recombination behavior, crystallite structure, and fabrication parameters to device-level efficiency and failure modes.Designed controlled experiments across photoanode architecture and processing conditions, then analyzed batch variation and reproducibility across fabricated devices.Ingenium NaturaeResearch EngineerMay 2023 - Jun 2024Delivered custom plasma and automation equipment for agri-food clients, turning incomplete requirements into commissioned machines spanning power electronics, embedded control, fluidics, reactor design, and industrial mechanics.Designed 20 kV discharge drivers, MOSFET switching stages, PID control loops, STM32 firmware, electrode and reactor geometries, Venturi injectors, and production CAD assemblies.Owned the full build cycle from client specification and system architecture through component selection, fabrication, wiring, firmware, validation, acceptance testing, documentation, and handoff.Debugged coupled electrical, thermal, fluidic, and mechanical failure modes on the shop floor until each machine met its operating requirements.
