I help teams build, stabilize, and operate production SaaS applications without disrupting users or revenue. If your Rails application is already live, costing too much to run, difficult to change safely, or needs new features without breaking existing workflows, I can take ownership and move it forward in a controlled, reliable way. I’m a senior full-stack engineer who works end to end across backend systems, infrastructure, payments, and AI integrations. My focus is not just shipping code, but reducing operational risk, improving reliability, and making sure the system is easy to maintain as it grows. Alongside traditional SaaS work, I build AI-powered features and agents that are designed for real production use. That includes white-label AI integrations, internal automation tools, and task-specific agents with guardrails, logging, and cost controls. I treat AI as part of the system, not a novelty or bolt-on. A common engagement for me is stepping into an existing Rails application and owning it. That may involve fixing production issues, improving performance, cleaning up deployment workflows, integrating payments, or modernizing infrastructure. I also frequently help teams move off Heroku to more cost-effective platforms such as Hetzner or AWS using Docker and Kamal, with a focus on zero downtime and long-term operability. Before software, I spent nearly 20 years in dealership and retail operations. That experience shapes how I work today. I understand revenue systems, customer impact, and why clarity and stability matter just as much as technical elegance. ⸻ What I Help Clients Achieve • Stabilize and maintain production Ruby on Rails applications • Ship new features safely into existing systems • Reduce infrastructure costs without downtime • Own payments, subscriptions, and marketplace flows • Integrate AI features that reduce manual work and improve UX • Improve performance, reliability, and background processing • Act as a fractional senior engineer for small teams ⸻ AI & Automation Capabilities • AI agents embedded inside SaaS products • White-label AI features integrated into existing platforms • Deterministic workflows around LLMs with validation and safeguards • AI-assisted reporting, content generation, and internal tooling • Integration with OpenAI, Claude, and local models • Logging, monitoring, and cost control for AI systems ⸻ Technical Focus • Ruby on Rails • Turbo, Hotwire and Stimulus • PostgreSQL and MongoDB • Docker and Kamal • Stripe subscriptions and marketplace payouts • Cloud deployments and production operations • Background jobs and async processing ⸻ How I Work I’m comfortable stepping into unfamiliar codebases, understanding how things actually work, and improving them without risky rewrites. I prefer small, safe changes, clear communication, and systems that are easy to reason about months later. I work well asynchronously, communicate clearly, and take ownership rather than needing constant direction. Clients typically bring me in when they want someone senior who can be trusted with production. I’m based in the US and work overlapping US business hours, which makes collaboration, reviews, and production support much smoother. If you need a reliable engineer who treats your product like a real business system, I’m happy to help.
