Full-Stack Developer · Founder · Aerospace Engineer

Six years of shipping - from a production trading-analytics SaaS and agentic-AI platforms, to missile guidance & navigation software proven against 600+ requirements. I'm strongest when ownership is broad, the problem is messy, and the output has to actually work.

  • Building an agentic-AI platform that automates middle-management workflows - status collection, risk detection, and weekly executive reporting - across Slack/Teams, Asana, and Calendar.
  • Designed the orchestration layer in TypeScript/Node: tool-call routing, enforced structured outputs, and scheduled workflows with idempotency, retries/backoff, and logging/metrics.
  • Implemented secure OAuth2 integrations (Asana, Google Calendar, Microsoft Graph/Outlook) with token storage & refresh, scope management, and a multi-tenant connector architecture.
  • Shipped MVP features for automated task/meeting creation and escalation rules; deployed via Docker with CI/CD to cloud infrastructure.

TradeFuse · automated trading journal SaaS

Founder & Lead Developer Apr 2020 - Jul 2025 · Los Angeles, CA

Five years of founder-level ownership - from an Excel proof-of-concept to a production SaaS with paying users and a near-six-figure acquisition offer. Everything from architecture and code to pricing, marketing, and support.

Engineering the Product

  • Took TradeFuse from alpha → beta → production: an automated trading journal & analytics platform with dashboards, trade tables, portfolio analytics, and broker-import workflows - born from an Excel VBA journal I'd built for my own trading.
  • Designed the end-to-end React/Node/AWS architecture - Lambda, API Gateway, S3/CloudFront, DynamoDB/RDS - with encrypted user data and clean client/server boundaries.
  • Implemented Auth0 SSO and the complete authentication/onboarding flow, REST APIs, and Docker/Heroku deployments with hands-on production support.

QuantumQuery - AI Inside the Product

  • Built QuantumQuery, an AI analytics engine: natural-language trading questions translated into charts, metrics, and insights - OpenAI prompt engineering tied to each user's real trading data, not a demo gimmick.
  • Turned vague user intent into structured application behavior: chart generation, metric summarization, and comparison workflows driven by plain English.

Running the Business

  • Owned the commercial side end to end: subscription pricing and Stripe billing, launch campaigns and promotions, user onboarding and support, and a feature roadmap driven by real user feedback.
  • Carried the product through go-to-market as a founder - UX design, branding, marketing assets, and customer conversations, not just the codebase.
  • The traction showed: TradeFuse drew acquisition interest, with a company tabling a near-six-figure offer to buy us out.

Systems Engineer II → Chief Engineer → Integration & Test Lead Feb 2020 - Jun 2025 · El Segundo, CA

Five years across the full arc of defense systems engineering - model-based design, flight test, production leadership, and finally leading integration & test for guidance/navigation software. Heavy focus: integration & test; secondary: software, hardware, and documentation.

Systems Engineer II - MBSE & Flight Test Feb 2020 - Aug 2022

  • Practiced Model-Based Systems Engineering and helped special projects build microlearning modules on MBSE best practices, adopted for subsequent company-wide employee training.
  • Flight-test campaign in Alaska evaluating receiver/GPS systems (including EGSS): flew on multiple test flights pulling up to 2G, characterizing receiver performance under G-loading and varied GPS-jamming levels.
  • Wrote MATLAB software to capture and process flight-test results for the GPS/receiver evaluation campaign; also designed internal SharePoint sites.
  • Briefly supported a handheld receiver product line, presenting our in-house handheld unit to potential customers.

Chief Engineer - Production Program Aug 2022 - Aug 2023

  • Stepped in as Chief Engineer for a production system that had lost its chief engineer, and carried it through production.
  • Owned alignment between product, design, production, and customer needs - heavy documentation ownership and drawing/schematic updates, all closed out.
  • Led guidance & navigation system upgrade work for the SM-3 missile, incorporating new business-collaboration software and a hardware upgrade.
  • Absorbed acceptance-testing practices that carried directly into the final program below.

Integration & Test Lead - Guidance & Navigation Software Dec 2023 - Jun 2025

  • Directed integration & test for advanced guidance/navigation software installed on receiver systems used aboard customers' airborne platforms - contributing code, and owning installation via flash or permanent burn onto the receiver cards themselves.
  • Rigorously verified the software against 600+ customer requirements with end-to-end traceability from high-level specification down to low-level code.
  • Authored test procedures, reported findings to both management and customers, and kept campaigns running smoothly through automation, custom software, and tight coordination.
  • The program became the company's gold standard for integration & test execution - with an exceptionally pleased customer.
