A note for Harmony AI team

Harmony is building in the part of AI I care about most: software that has to work inside a real operation, not just look impressive in a demo. I have spent 20+ years coding across full stack products, infrastructure, support, and the messy connective tissue between systems and people. I have rebuilt servers and networks on site, owned datacenter and client infrastructure, built internal operational tools, and shipped an acquired SaaS product. Today I code AI tools and workflows around retrieval, structured outputs, classification, orchestration, evaluation, and human review. I know how quickly a clean model assumption hits ugly production reality, and I actually like that part. Harmony's mix of agents, retrieval, action, factory visits, and end-to-end accountability feels unusually close to how I already work. I would love to help build the systems that make factory knowledge usable and operational work move.

Applied AI for real operations

Retrieve and ground

I code retrieval, embedding, search, and source-aware workflows that turn scattered operational knowledge into useful context.

Reason and act

I build structured outputs, classification, natural-language interfaces, and tool orchestration that can move work while keeping people in control.

Evaluate in production

I pair AI behavior with evaluation harnesses, tests, observability, guardrails, and human review because a convincing demo is not the finish line.

Understand the operation

My background spans software, infrastructure, support, datacenters, and on-site business IT, so I am comfortable tracing a workflow across systems, machines, and people.

I build the product when the workflow is too important for another generic tool.

Summary

I am a product engineer and systems builder who thrives where software, operations, and infrastructure collide. For more than 20 years, I have taken ambiguous workflows from stakeholder discovery and data modeling through full stack implementation, production rollout, and support. I code the products myself, and I use AI tools I developed through that engineering work to accelerate research, testing, automation, and delivery without outsourcing technical judgment. My background spans an acquired Amazon SaaS product, enterprise infrastructure, real-time internal tools, deterministic game systems, open-source platforms, and five years helping crypto teams ship products and raise money.

Featured Products

Technomancy.IT

Founder and Product Engineer

Technomancy is the name I gave the instinct I have followed since childhood: understand the hidden logic inside technology, reshape it, and make it useful for people. I designed and built Technomancy.IT as both a client-facing product and the operating layer behind the company. The platform unifies CRM, support, scheduling, browser meetings, collaborative whiteboards, billing, analytics, content operations, infrastructure telemetry, and AI-assisted workflows across a Next.js, TypeScript, PostgreSQL, and containerized production stack. The result is one extensible system our team can adapt around a client instead of forcing the client into a pile of disconnected SaaS tools.

KTHX.fun / Ricoshot

Current Product

Building the live KTHX.fun game surface and the deterministic engine beneath it. The frontend turns Ricoshot into a complete arcade product with an arena browser, mass matches, bot play, tutorials, cabinet shopping, rankings, wallet flows, and an onchain radio experience. Under that interface, a C++20 simulation compiled to WASM uses fixed ticks, replayable input logs, checkpoint validation, and server-authoritative mechanics so clients converge under lag and reconnects while match outcomes remain independently verifiable.

Velatis

Client Product

Working with the Velatis team on product engineering, AI automation, and the production systems behind a private research workspace for astrology, tarot, and symbolic practice. The platform combines interactive tools, identity and access, private notes, deterministic chart data, sharing, payments, administration, and context-aware AI while treating privacy and user ownership as architectural requirements.

Velatis Charts

Open Source

Built an open-source, stateless astrology calculation and rendering platform with typed APIs, deterministic share URLs, accessible SVG output, and a privacy-first data contract. It supports natal, comparison, transit, tropical, and sidereal workflows without retaining personal birth data, making the engine useful as both a standalone product and an embeddable service.

Core Skills

Product and Full Stack

Translate incomplete operational requirements into domain models, user flows, production interfaces, APIs, background jobs, and measurable outcomes. I work across React, Next.js, TypeScript, Node.js, PostgreSQL, Redis, REST and GraphQL APIs, WebSockets, real-time collaboration, authentication, payments, and admin tooling.

ReactNext.jsTypeScriptNode.jsPostgreSQLAPIs

AI Tools and Automation

Build AI into real product workflows through retrieval, embeddings, structured outputs, classification, natural-language interfaces, tool orchestration, evaluation harnesses, and human review. I also code the AI-assisted development tools I use, so faster delivery still sits on explicit architecture, source control, tests, observability, and accountable engineering judgment.

LLMsPrompt EngineeringAgentsAutomationSearchEmbeddings

Operations and Integrations

Model the messy work between systems: scheduling, email triage, support queues, CRM state, ticketing, notifications, approvals, dashboards, and handoffs. I work directly with operators and non-technical stakeholders, identify the actual constraint, then replace fragile manual steps with auditable software and integrations.

WorkflowsEmailCalendarsDashboardsSupportAnalytics

Systems and Delivery

Own the release path and the runtime: Linux, AWS, Kubernetes, Docker, Terraform, Ansible, CI/CD, Nginx, networking, monitoring, security, backup, disaster recovery, and datacenter operations. I design for operability, instrument failure modes, and stay responsible after the deploy.

Professional Experience

Technomancy IT LLC - Founder / Product Engineer / Systems Lead

2015-Present

Founded a product engineering and managed-technology company delivering web applications, operational tooling, AI automation, blockchain systems, and production infrastructure. Built with React, Vue, Next.js, TypeScript, Node.js, PostgreSQL, Redis, Socket.IO, smart contracts, Docker, Kubernetes, and cloud and on-prem systems. Operated from Wray, Colorado for three years and became a go-to technology resource across the town, translating rural business and community needs into practical software, hardware, networking, and support. Managed Excell Services' complete IT function and led its end-to-end infrastructure modernization: audited and rebuilt on-site servers, negotiated a fiber agreement that saved thousands of dollars, implemented multi-location backup and recovery, engineered wireless links between separated offices, supported roughly 30 employees, and completed the migration without business interruption. For Blade Construction, designed a custom ticketing and CRM workflow and owned the surrounding IT environment. Over the last five years, partnered with crypto and creative teams on games, marketplaces, art platforms, websites, NFT products, launch operations, and fundraising systems.
