I’ve spent eight years being that person. One client kept me for four years and 2,224 hours; another called me “always there when we have company crisis.” WHAT CLIENTS HIRE ME FOR • Prototype to production. You have an app built with Lovable, Bolt, Cursor, v0 or a previous developer. It needs real auth, roles and permissions, payments, tests and a stable deploy. [CONFIRM at least one example] • Rescue and take-over. Undocumented codebase, original developer gone. I stabilize it, document it and extend it without a rewrite, unless a rewrite is truly cheaper. • AI features that earn their keep. Support assistants with RAG over your docs, structured-output workflows and agent tool-calling, with cost limits, guardrails and human handoff when the model isn’t sure. • Audits before you spend. A fixed-scope review of your code, database, auth and integrations, with ranked risks and the smallest next fix. HOW I WORK • Daily written updates and a working build you can click every week. • Fixed-price milestones or hourly, whichever suits the project. • I write and review every line myself. I use AI coding tools (Claude Code, Cursor) for speed, then read, test and own the result. • Your GitHub, hosting and accounts from day one. Handover docs written so another developer can take over. NDA and IP assignment are fine. • If a deadline will slip or you’re about to pay for the wrong fix, you hear it from me first. TRACK RECORD • Senior Software Engineer at IZEA for 3+ years: Rails, Docker, AWS, REST and GraphQL on a creator-economy platform. • 25 projects, 5.0 average, three clients retained for 2+ years. • Client CTOs have reviewed my code directly and confirmed it holds up. • I run Qbitx Systems, but you work with me personally, not a rotating team. STACK Frontend: Next.js, React, TypeScript, Tailwind, Vue.js Backend: Node.js, Express, Ruby on Rails, PostgreSQL, MySQL, MongoDB, GraphQL, REST AI: OpenAI API, Claude API, RAG, AI agents Payments and infrastructure: Stripe, Supabase, AWS, GCP, Heroku, Docker, Kubernetes, CI/CD Testing: RSpec, Minitest, Capybara, Jest/Playwright AVAILABILITY More than 50 : hours per week. GOOD FIT: the product matters to your business, it’s live or nearly live, and you want someone who sticks around. NOT A FIT: you want the cheapest rate, or a throwaway demo by Friday. START HERE: Send what’s live, what’s breaking or what you want built, your stack and your deadline. I’ll give you an honest recommendation, including if someone else is a better fit.
