Velatis research platform preview
Client Product

Velatis

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. Build research-heavy product workflows around private user data. 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.

AI IT Support for Small Business

Built an AI-enabled SaaS support system designed to bring responsive local IT help and business-specific customization back to small businesses at a fraction of traditional managed-service pricing. The product unifies intake, CRM, scheduling, secure support, browser meetings, collaborative whiteboards, billing, analytics, infrastructure telemetry, and AI-assisted workflows so a small technical team can deliver personal service without enterprise overhead.

Live KTHX.fun Ricoshot arena frontend
Current Product

KTHX.fun / Ricoshot

Designed and built the entire KTHX.fun product end to end, with Ricoshot as its only game: the brand and landing experience, arena browser, game frontend, mass matches, bot play, tutorials, cabinet shopping, rankings, account flows, integrated radio, multiplayer services, and the deterministic engine beneath it. The C++20 simulation compiles to WASM and 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 Charts

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.

02 / How I build

Engineering Capabilities

Product engineer and founder with 15+ years building software and systems around hard-to-define product problems. Technomancy IT grew from freelance work into a small technical shop, where I was usually the only engineer or lead engineer owning discovery, architecture, product code, infrastructure, deployment, and support across crypto, security, web applications, and SaaS.

01

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.

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.

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.

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.

Career record

Experience Behind the Work

01
2015-2019

Front Range Internet - Senior Systems Engineer / Datacenter Architect

Led end-to-end technical readiness and infrastructure remediation for annual SOC 1 and SOC 2 audits under SSAE 18 at a 30,000-square-foot commercial data center in Fort Collins serving enterprise clients, maintaining compliance. Served as the primary technical point of contact for external auditors, translating infrastructure architecture, access controls, and failover protocols into audit artifacts. Owned disaster recovery and backup verification protocols, including automated testing schedules, and drafted and enforced engineering SOPs aligned with audit control objectives; the organization passed every year I led the process. Led the NOC team and served as the primary on-call engineer for escalations, designing and managing monitoring systems for datacenter and client operations. Served as the senior systems engineer and datacenter architect, modernizing workloads from hardware-centric virtualization to reproducible Docker, Docker Swarm, and Kubernetes platforms. Migrated legacy monitoring from Nagios to Zabbix through a multi-step cutover that included a severely unhealthy legacy database environment costing roughly $10,000 per month in AWS charges. Codified infrastructure and deployment workflows with Terraform, Ansible, and CI/CD; led capacity planning, recovery, client migrations, runtime operations, and incident response.

Technomancy IT LLC - Founder / Product Engineer / Systems Lead

Founded Technomancy IT as a freelance engineering practice that grew into a small technical shop. Earned Upwork's Top Rated badge and ranked among its top 10% of freelancers before building a referral-based client base across emerging technology, security, web applications, and SaaS. Usually served as the only engineer or lead engineer, owning discovery, architecture, product development, infrastructure, security, deployment, and ongoing operations. Implemented OAuth/OIDC extensively in application and API authentication flows, including PKCE and token exchange. Built selected enterprise-facing identity capabilities into Technomancy.IT and client products, including SAML/SCIM integrations, AWS IAM and Microsoft Entra ID implementation work, workload identities, secrets, and tenant-aware access controls, with the depth centered on product implementation and integration. Helped teams ship products and fundraising systems used in raises totaling millions of dollars; built and managed deterministic transaction systems and independently verifiable systems that held millions in value. Delivered client work across React, Vue, Next.js, TypeScript, Node.js, PostgreSQL, Redis, Docker, Kubernetes, and cloud and on-prem infrastructure. Also managed Excell Services' complete IT function, modernized its network and recovery systems for roughly 30 employees, and built Blade Construction's ticketing and CRM workflow. Now evolving the practice toward a collaborative model that brings in strong specialists when the work benefits from more than one engineer.

MinePocket

Built and operated MinePocket, one of the earliest live Minecraft: Pocket Edition online communities, before the mobile game offered native internet multiplayer. Productized a virtual-LAN path that used a home-computer proxy to relay the client's LAN-only traffic to hosted servers, proving that internet-connected mobile play was technically viable and that players wanted it. Archived forum snapshots show the account sequence gaining 19,630 registrations in ten days at peak and later crossing 250,000 cumulative registrations. Mojang CEO Carl Manneh later asked us to stop the unofficial connector because Mojang was adding WAN connectivity directly to the client; the MinePocket server software and community could continue without it. I owned product validation, community operations, reliability, and the client-to-network experience rather than the underlying server engine.

NuPrice - Amazon Repricer for Resellers

Designed, built, and operated an Amazon reseller SaaS product that ingested marketplace and competitor data, evaluated repricing rules, and automated price decisions before the current wave of AI tooling. NuPrice combined a Node.js application stack with real-time monitoring, analytics, account and subscription workflows, a CMS, and support embedded directly in the product. The platform solved operational gaps competing tools did not and was acquired.
