Internal Tools Engineer — Full-Stack TypeScript | Next | Nx Monorepo | Business Automation

Summary​

Software engineer specialized in designing and building full-stack web services and internal tools that automate operational complexity. 7+ years across telecom, healthcare, and crypto — each taught the same pattern: unify siloed data, build reusable pipelines, surface decisions that matter to humans.

Currently building internal tools and web services for a crypto + AI platform using TypeScript, NestJS, and Nx monorepo with hex architecture. Focus on systems that scale with operational cadence: data workflows, admin dashboards, transaction monitoring, and automation that lets teams do more with clarity. The same architecture thinking is documented at mycelium and Three Spaces — how internal tools become the coordination layer where intent meets execution.

Technical Stack​

Experience​

Business Engineer — Dreamineering (2023–Present)​

Full-stack internal tools and web services for crypto + AI platform

• Designed full-stack TypeScript services using Nx monorepo with hex architecture; enables clean separation of concerns and testable, scalable code for mission-critical tools
• Built admin dashboard and user management tools used daily by ops and engineering teams; integrated transaction monitoring, reporting, and operational workflows
• Owned deployment pipeline end-to-end: CI/CD configuration (GitHub Actions), environment setup, Vercel integration, monitoring and alerting — responsible for shipping features safely to production
• Integrated AI tooling for developer productivity and content workflows; demonstrated ability to adopt emerging technologies and translate them into internal productivity gains
• Worked across teams (product, ops, design) to translate complex requirements into testable, maintainable code

Stack: TypeScript, Next.js, DrizzleORM, Supabase, Docker, Nx, GitHub Actions, Vercel

Web3 Game Blockchain Strategist — Dynasty Studios (2022)​

Blockchain engineering and game economy design for Web3 gaming platform

• Designed tokenomics and smart contract architecture balancing game balance with economic viability
• Built internal tools for game economy simulation and balance testing; enabled non-technical game designers to iterate on mechanics
• Translated game design requirements into technical specifications and implementation plans

Business Analyst & Developer — Gensolve (2014–2021)​

Product development for healthcare practice management SaaS (~200 active clinics)

• Engineered ETL automation migrating 50+ different source data formats into unified data model; enabled clinic onboarding in days instead of weeks
• Designed validation layer catching data quality issues before production import; prevented costly errors and rework
• Built staging environment enabling non-technical staff to review and approve transformed data before import; critical for building trust in complex data migrations
• Created extensible adapter framework making new source systems additions to the platform, not new projects
• Owned data import experience end-to-end: ETL pipeline, validation, staging UI, production import, post-import reconciliation

Stack: C#/.NET, Vue.js, SQL Server, ETL pipelines, Jira workflows

Product Manager & SME — Subex / WorldCom (2000–2006)​

Telecom decision support, routing optimization, revenue assurance

• Built unified routing optimization tool aggregating data from 4+ siloed systems (switches, billing, pricing, mediation); enabled intelligent carrier selection balancing cost, capacity, and quality
• Reduced RFP response time from days to hours through automated data aggregation and decision support; strategic advantage in high-speed telecom market
• Designed reference data system eliminating arbitrage losses from outdated dial codes and routing rules
• Collaborated across network ops, trading, finance, and legal to translate business requirements into technical solutions

Project Engineer — Ashton Project Services (1996–1998)​

Factory design, build, and commissioning

• Process control, feedback loops, capacity planning, systems engineering discipline that directly transfers to software architecture thinking

Education​

Mechanical Engineering — Waikato Institute of Technology, NZ (1992–1994)

The Pattern​

What connects telecom routing, healthcare ETL, and crypto workflows?

INTENT → ROUTE → INFRASTRUCTURE → SETTLE → FEEDBACK

Same architecture discipline. Different domains. Internal systems that make operational complexity visible and automatable.

This is the third space pattern: where inner (intent, mission) meets outer (infrastructure, execution) through internal tools that make coordination visible. See Space Industry and Telecom Industry for how this applies across domains.
