Hi Quindar team,

I call myself a technomancer. Technology has felt like magic to me since I was a kid, and I still enjoy figuring out how to make complicated systems work together in a way someone can actually use. Satellite operations is a new domain for me, but the engineering problem in your posting feels familiar: understand what the operator needs, connect the software and infrastructure behind it, and make the result dependable when it matters.

I like that you are looking for a software engineer rather than requiring someone to arrive as a satellite expert. My career has moved between building applications and operating the systems they depend on. Through Technomancy IT, I take client products from discovery through implementation, deployment and support. React, TypeScript and Node.js are central to much of that work, alongside authenticated APIs, relational data and tenant-aware services. Python has also been part of my systems and project work. I would bring that breadth while learning the particular mission workflows and backend conventions your team uses.

At FRII, I ran the NOC and handled production escalations through a multiyear engineering tenure. I migrated workloads from Hyper-V and VMware ESXi into Docker and Kubernetes, used Terraform and Ansible for repeatable infrastructure work, and upgraded server and firewall systems. I worked there for years before becoming the sole systems engineer for about a year after a company purchase, with the NOC continuing first-line coverage. That responsibility taught me to look beyond whether a component was running and understand whether the whole service was doing what people needed.

The same perspective shows up in my software work. NuPrice was a long-term client engagement where I built and operated the application, billing, customer support and technical operations. It connected marketplace data and pricing rules with accounts, subscriptions and the user-facing workflow. Being responsible for both the product and the issues people brought back made me comfortable moving across the stack instead of treating the frontend, backend and operation as separate problems.

The Technomancy platform I am building takes that approach into support, CRM, scheduling, billing and infrastructure context with TypeScript, Next.js and PostgreSQL. Its delivery tooling records image and deployment identity, applies migrations and checks real HTTP responses. Separate restore-verification tooling checks a backup and restores it into a disposable database. I enjoy making that kind of operational behavior visible and repeatable, particularly when a team needs to change a system without losing track of what is running.

I am also building Kerf, formerly Weft, a TSX framework with its own compiler and the Warp UI toolkit. It is early development, but it reflects the self-directed work your posting calls out: digging into the tools, making the contracts explicit and improving the feedback people and coding agents get while building. I would bring that curiosity to Quindar without confusing an independent framework project with experience operating spacecraft.

I am based in Milliken and interested in working with your Arvada team. I would welcome a conversation about the customer-specific capabilities and core product work you need help with. When operators can focus on the mission because the software makes the complicated parts clear, that is the kind of practical magic I want to help build.

Experience

Technomancy IT LLC · 2015-Present

Founder / Product Engineer / Systems Lead

Build client applications, authenticated APIs and tenant-aware services through deployment and support. Connect product requirements with the data, infrastructure and operating model behind them.

Deep dive

I lead a referral-based technical practice, translating client needs into products and systems I also help operate. React and TypeScript interfaces sit alongside APIs, data, infrastructure and support; the work requires understanding how a customer uses the system as well as how it is built.

Application and API authentication work includes OAuth/OIDC, PKCE and token exchange. Tenant-aware shared services connect client-facing products and internal operations while keeping their access boundaries distinct. I bring in specialists where their craft helps the project and make the system and delivery responsibilities clear to contributors.

NuPrice | Client engagement within Technomancy IT · 2019-2021

Product Engineering and IT (Long-Term Contract)

Built and operated a long-term client application connecting marketplace inputs, pricing rules, accounts and billing. Owned customer support and technical operations alongside full-stack delivery.

Deep dive

NuPrice was a long-term client engagement from 2019 to 2021, beginning while I was still at FRII. I built and operated the reseller application and owned its billing, customer support and technical operations.

The application brought marketplace and competitor data into user-defined repricing rules and automated price decisions, with monitoring and analytics alongside accounts, subscriptions, a CMS and embedded support. That sustained responsibility meant following issues from the customer-facing workflow through the application and its operation. The product was acquired; my role was the client’s technical delivery, not ownership of the company.

Front Range Internet Inc. · 2015-2020

Senior Systems Engineer / Datacenter Architect

Ran the NOC and production escalations over a multiyear tenure. Migrated Hyper-V/ESXi workloads into Docker/Kubernetes and used Terraform/Ansible in repeatable infrastructure work.

Deep dive

At Front Range Internet Inc., I ran the NOC and was a lead engineer through a company purchase. Later, after the senior engineer above me left, I took sole systems-engineering responsibility for approximately a year, with the NOC continuing first-line coverage and escalating issues to me. That was one period within my 2015–2020 tenure, not the whole engagement.

I migrated workloads from Hyper-V and VMware ESXi to Docker and Kubernetes, upgraded server and firewall infrastructure, and owned recovery verification, monitoring, escalations and engineering procedures. Terraform and Ansible supported repeatable infrastructure work. I also ran the SOC 1 and SOC 2 audits and worked with the CEO and CIO while keeping the operating environment supportable through change.

Office Evolution · 2014-2015

Systems / Software Engineer

Built SQL/MongoDB applications connecting CRM, onboarding, provisioning and service operations across locations. Worked with company leadership to make cross-team handoffs explicit.

Deep dive

Office Evolution’s operational work crossed departments and locations. I built centralized SQL- and MongoDB-backed applications connecting CRM, provisioning, onboarding and service operations so those handoffs were represented in shared systems.

The role combined software with the architecture around it: learning how people needed to work together, translating the handoffs into explicit workflows and supporting the surrounding systems across locations and client environments. I worked with the CEO and CIO as part of that delivery.

PlumChoice / Everon · 2012-2014

Network & Systems Engineer

Engineered customer networks and endpoints for managed-service clients. Built diagnostic tooling and handled on-call issues directly with business owners and end users.

Deep dive

At PlumChoice / Everon, I worked as a network and systems engineer across managed-service clients, supporting networks and endpoints and communicating directly with business owners and end users. The work required diagnosing a problem in its business context rather than stopping at a single device.

I used monitoring and diagnostic tooling, built support tools around recurring operational needs, and handled on-call issues. Working across client environments developed the practical troubleshooting and communication I still bring to software delivery and production support.

Antivirus services were part of the managed-services work. The record does not identify a particular antivirus vendor or an endpoint-agent implementation, so I distinguish operating and supporting these environments from writing a commercial agent.

IBM · 2010-2012

Infrastructure and Systems Focal

Supported enterprise infrastructure across application and vendor teams. Automated audit/backup workflows and managed virtualization labs with coordinated incident and change ownership.

Deep dive

At IBM, I was the infrastructure and systems focal for shared enterprise environments. The work crossed application, infrastructure, vendor and business teams, with incidents and changes requiring coordinated ownership rather than isolated fixes.

I automated audit and backup workflows, managed virtualization test labs and hosted desktop platforms, and supported access, change and escalation work around shared infrastructure. That experience established an operating perspective that complements my later full-stack product work.

Selected work

Founder-built platform · In development

Technomancy | Shared business services

Building TypeScript/Next.js/PostgreSQL software joining support, CRM, scheduling and billing through tenant-aware services. Implemented versioned release and recovery-verification tooling.

Deep dive

Technomancy is my technical practice and the client-operations platform I am building around it. TypeScript, Next.js and PostgreSQL connect support, CRM, scheduling, billing and infrastructure context. Tenant-aware shared services keep client and internal access boundaries clear.

The delivery tooling derives container image tags from Git, applies database migrations, records deployment status and checks health and public HTTP responses. Separate restore-verification tooling checks a backup checksum and restores into a disposable PostgreSQL instance. These are implemented capabilities, not a claim that every release or scheduled restore test passed.

A configured desktop meeting-client build workflow targets Windows EXE/MSI, Linux AppImage/DEB and macOS DMG/ZIP artifacts. This is cross-platform installer-build configuration, not a claim that every target passed or that every installer is signed or notarized.

Long-term client engagement · 2019-2021

NuPrice | Marketplace-to-customer workflows

Built the client application connecting marketplace inputs and pricing rules with accounts, subscriptions, billing and embedded support. Owned delivery and ongoing technical operations.

Deep dive

NuPrice was a long-term client engagement from 2019 to 2021, beginning while I was still at FRII. I built and operated the reseller application and owned its billing, customer support and technical operations.

The application brought marketplace and competitor data into user-defined repricing rules and automated price decisions, with monitoring and analytics alongside accounts, subscriptions, a CMS and embedded support. That sustained responsibility meant following issues from the customer-facing workflow through the application and its operation. The product was acquired; my role was the client’s technical delivery, not ownership of the company.

Independent framework project · In development

Kerf and Warp | Compiler-backed application tooling

Building an agent-oriented TSX framework with its own compiler and Warp UI toolkit. Routing, authentication, data and actionable compiler diagnostics make application boundaries explicit.

Deep dive

Kerf is my agent-oriented TypeScript/TSX framework, formerly called Weft. I am building its own compiler, the Warp UI toolkit and a full-stack layer for routing, authentication and data. The preview describes small direct DOM/page updates and compiler feedback intended to help coding agents act on errors.

It is early development, not a claim of large production adoption or a React implementation. My established React and TypeScript work informs the design, but Kerf is an independent framework. The resume templates currently use pinned legacy Weft/Warp packages; the project rename is not itself a compiler migration.
