## Target
Staff Product Engineer – Full Stack / AI Products at Russell Tobin · San Francisco, CA (hybrid; monthly travel caveat)

## Profile
I build across the boundary between product code and the systems that keep it running. That means making useful interfaces, codifying deployment, improving observability, and staying accountable for the handoff from implementation to dependable production behavior.

## Relevant strengths
- Full-stack product engineering
- Platform engineering and operations
- Applied AI and automation
- Technical leadership and collaboration
- Data systems and reliability

## Relevant experience
- **End-to-end product platform:** Designed and built a Next.js, TypeScript, PostgreSQL, and containerized platform spanning CRM, support, scheduling, meetings, billing, analytics, infrastructure telemetry, and AI-assisted workflows.
- **Founder-led product delivery:** Earned Upwork's Top Rated badge and ranked among its top 10% of freelancers before building a referral-based practice. Usually served as the only engineer or lead engineer, helping teams ship products and fundraising systems used in raises totaling millions of dollars and managing smart contracts that held millions in value.
- **Acquired Amazon reseller SaaS:** Designed, built, and operated an Amazon reseller SaaS product with marketplace ingestion, repricing automation, analytics, account workflows, and support built directly into the application.
- **Datacenter and platform operations:** 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 while designing and managing monitoring systems. Modernized workloads into Docker, Swarm, and Kubernetes platforms and codified deployment with Terraform, Ansible, and CI/CD. 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.

## Focus for this application
The strongest match is practical ownership: understand the operator or developer problem, ship the tool, and leave the system more observable and reliable.
