Stealth Startup | Confidential Field Operations Platform

Feb 2026 – Present • Remote

For a stealth startup's confidential field-operations platform, I owned modernization planning for AWS middleware connecting a field application to multiple enterprise systems, combining hands-on cloud engineering with release strategy, dependency mapping, stakeholder alignment, and production reliability work.

Key Achievements

Converted an open-ended Python runtime mandate into a dependency-aware modernization program for 90+ AWS Lambda functions across three environments.
Inventoried functions across Development, Test, and Production, mapping source repositories, shared Lambda layers, architectures, aliases, runtime versions, ownership, and invocation paths.
Evaluated Python 3.11, Python 3.12, and Amazon Linux compatibility for a phased Python 3.9 runtime upgrade, including a proposed 12-function pilot.
Incorporated lessons from a prior rollback affecting roughly 30 functions to define dependency risk tiers, release sequencing, QA scope, acceptance criteria, and promotion controls across development, test, and production.
Designed release controls using published versions, stable aliases, staged traffic, monitoring, rollback thresholds, and environment promotion.
Diagnosed production failures across distributed AWS integrations by tracing data through databases, API Gateway, Lambda functions, CloudWatch logs, source code, and external dependencies.
Aligned engineering, QA, delivery leadership, and dependent-system stakeholders around migration scope, validation requirements, rollout timing, and operational risk.
Identified gaps in production provenance, reactive alerting, source-of-truth management, and recovery procedures, then proposed standardized controls to reduce release and operational risk.
Implemented and maintained Python-based cloud integrations and configuration changes supporting critical business workflows.
Presented architecture, delivery, and risk tradeoffs to technical and non-technical stakeholders while coordinating decisions across teams with competing priorities.

Scribe

Apr 2023 – Dec 2024 • Remote

At Scribe, I rebuilt the performance-critical core of the codebase—resolving the CPU and memory issues that had been slowing the team down—and shipped new AI-powered tooling to speed up how engineers found and fixed bugs.

Key Achievements

Led a performance overhaul that reduced sustained CPU peaks from 99% to 15% and lowered memory pressure, unlocking enterprise-scale workloads without new hardware.
Built "Bug Buddy," an AI-powered triage assistant that automated roughly 75% of manual classification and surfaced duplicate and regression patterns before engineering assignment.
Architected and led a cross-team refactor that retired over 15,000 lines of legacy code and moved the entire front end to TypeScript.
Rebuilt the front-end API layer to eliminate redundant calls and noticeably speed up rendering—without pausing active feature work.
Designed democratic decision processes and living documentation so engineering teams could ship and review features faster together.
Overhauled image processing and error-reporting pipelines—introduced WebP, resolved data-integrity issues, and reduced load times by 20%.
Prototyped an LLM-driven migration tool that automated 80% of our Redux→React Query conversion, saving the team dozens of hours.

Green Bits Inc & Dutchie

Apr 2017 – Dec 2022 • Remote

At Green Bits (acquired by Dutchie), I built our first white-labeled React dispensary menu—saving clients dozens of hours of manual work each week—architected the systems that kept the platform reliable through major traffic spikes, and managed the company's DevEx pipeline.

Key Achievements

Built the first white-labeled React dispensary menu, cutting manual inventory updates and custom branding work by 40+ hours a week.
Ran load testing, complex query analysis, and chaos engineering to keep systems resilient through traffic reaching 4x normal volume.
Implemented redundant data storage and replication alongside failover strategies, ensuring data integrity and reliability across multiple data centers.
Owned the DevEx team's product roadmap, working with other teams to translate criteria into actionable items and keep the team shipping high-value features.
Engineered pre-production and staging environments with feature branches and Kubernetes, eliminating QA environment queues and cutting test-cycle time by more than 80%.
Prototyped "Brick", an offline-first data persistence layer (TypeScript/React Native → later Dart) to guarantee seamless UX and reliable government reporting when connectivity drops.
Owned the company's continuous integration and delivery (CI/CD) pipeline, implementing containerization and parallelized testing to speed up test execution and keep deployments reliable.

FynX

Reactive incremental computation for Python

FynX is a reactive incremental-computation library for Python, designed for application state and any other problem where results must remain synchronized with inputs that change over time. You describe a graph of changing values and the computations derived from them; when an input changes, FynX recomputes the affected part of the graph, keeps unobserved work lazy, and notifies subscribers where a result meets the outside world.

Inspired by MobX and functional reactive programming, FynX works with ordinary Python functions and has zero core dependencies. It can be introduced around a single computation without requiring the rest of the project to adopt a new architecture.
