Music has been my life for over 25 years. I help artists transform rough ideas into songs that feel finished, emotional and ready for release. Whether you have just a voice memo, a guitar riff or a complete demo, I can take it to the next level. What I can do • Music production from scratch • Song arrangement • Original composition • Bass guitar recording (my favorite instrument) • Electric & acoustic guitar recording • Live-style drum programming • Vocal production & backing vocal arrangements • Demo production • Mixing preparation & production consulting • AI-assisted mastering and final polishing (when it actually improves the result) I especially enjoy working on projects that need energy, character and real musicianship instead of generic loops. Genres Rock • Alternative • Hip-Hop • Pop • Indie • Cinematic • Game Music • Trailer Music • Electronic Hybrid I believe every song deserves its own identity. My goal isn’t simply to finish a track—it’s to make people want to listen again. I’m easy to communicate with, responsive and genuinely enjoy collaborating throughout the creative process. If you already have a sketch, demo or even just an idea… Send it over — let’s build something exciting together.

Most freelancers sell tasks. I take ownership of products. Clients usually come to me at one of three moments: → They have an idea that needs to become a real, revenue-ready product. → They have a half-built or AI-generated app that's 80% done and stuck. → They have a live product and need a senior engineer who'll stick around to evolve it. 𝗪𝗛𝗔𝗧 𝗜 𝗕𝗨𝗜𝗟𝗗 ▸ Web Apps & SaaS: MERN stack (MongoDB, Express, React, Node) and Next.js: MVPs, dashboards, client portals, booking systems, membership platforms ▸ WordPress & WooCommerce: custom builds, Elementor, plugins, integrations, membership and e-commerce sites ▸ Shopify: store builds, custom functionality, speed and conversion improvements ▸ AI Agents & Automation: Chat and voice agents, automated lead follow-up, workflow automation (GoHighLevel, OpenAI/Claude APIs, custom integrations) 𝗛𝗢𝗪 𝗜 𝗪𝗢𝗥𝗞 — 𝗔𝗡𝗗 𝗪𝗛𝗬 𝗖𝗟𝗜𝗘𝗡𝗧𝗦 𝗦𝗧𝗔𝗬 Products are always in "improvement" My typical engagement starts with one clearly scoped milestone, so you can judge my work with low risk. From there, most clients keep me on for the life of their product — new features, integrations, performance, and AI capabilities added month after month by someone who already knows the codebase. AI is Good but I use 15 years of engineering judgment to build things that don't break in production. That combination - AI speed with senior accountability is what you're actually hiring.
