Andrew – Python, React, Typescript
Andrew is a Senior Full-Stack Engineer with 15+ years of commercial experience across startups and enterprise, combining strong Python and React depth with applied AI integration. He's built products from scratch — IoT robotics platforms, AI-powered SaaS tools, geospatial social apps — and scaled them across infrastructure, user growth, and team capability. What makes him stand out is genuine product ownership: he consistently bypasses stakeholder noise to build for actual end-users, drives architectural decisions independently, and communicates trade-offs with precision.

Lead Engineer
Carbon sequestration startup developing a fleet of autonomous terraforming robots that inject wood underground to capture carbon and generate carbon credits. The platform covers real-time robot control across multi-acre field deployments and a site monitoring system for managing land elevation progress at scale.
- Led a cross-functional software and mechanical engineering team to design, source, and build a fleet of autonomous terraforming robots deployed across 2-acre work sites.
- Built an iOS control application communicating with robots via BLE and Modbus protocols, achieving sub-300ms latency across the full deployment area.
- Developed a real-time monitoring platform for carbon injection sites, giving site managers visibility into land elevation progress and tools to make testable, data-driven decisions.
- Architected backend infrastructure using NestJS and Cloudflare to support multi-site coordination, observability, and geospatial data rendering via MapBox.
Founding Engineer
AI-powered reference-checking platform that automates recruiter workflows by delegating reference collection to AI. Candidates respond via SMS, voice, or web — eliminating friction and scaling throughput without adding headcount.
- Scaled the platform from MVP to a full production service, achieving 5× user capacity at 1/3 the original infrastructure cost.
- Integrated OpenAI to automate reference collection across SMS, voice, and web channels, growing monthly candidate conversion from 15 to 40.
- Architected the Python/Java backend with Spring Boot and MySQL on AWS, including HubSpot integration for recruiter pipeline automation.
- Designed the full React frontend with a modular component system, landing page, and brand identity — cutting development time in half.
Founding Engineer
Social outdoor adventure platform connecting outdoor enthusiasts to activities and adventure partners. Features cooperative geospatial editing, in-app messaging, and ML-driven athlete matching.
- Built the native iOS app in Swift from the ground up to connect outdoor enthusiasts with adventures, ski partners, and local guides.
- Re-architected the full backend from a Firebase prototype to a scalable DigitalOcean/Docker stack, achieving 12× traffic capacity at the same infrastructure cost.
- Designed and trained a TensorFlow ML model for automated athlete categorization, contributing to 3× user growth.
- Integrated MapBox for real-time cooperative geospatial editing and location-aware activity discovery.
Senior Full-Stack Engineer
Checkout platform engineering at one of the world's largest fintech companies. Scope spanned developer tooling, A/B experimentation infrastructure, and integration work with new products post-acquisition — contributing to measurable uplift in conversion and revenue at scale.
- Built internal logging and debugging tooling to surface bottlenecks across the development cycle, improving transparency around downtime and incident response.
- Formed and led a team to develop an A/B testing framework for UI variants, delivering a 3% lift in user retention.
- Led a cross-functional team applying device-, region-, and behavior-based heuristics to checkout flow redesigns, achieving a 30-point conversion increase.
- Partnered with post-acquisition Honey and Venmo teams to identify and resolve customer friction points, contributing to $30M in incremental revenue.
Senior Front-End Engineer
Enterprise WiFi network management application used by IT teams to configure and monitor wireless infrastructure.
- Developed and shipped UI features for the HiveManager network management application, driving a 15% improvement in usability and retention.
- Introduced Angular and established a cohesive application architecture across the frontend codebase, cutting development time by a third.
- Chaired stand-ups and transitioned the team to a continuous release cycle, clearing a full year's backlog of outstanding bugs.
