    As a CTO and co-founder of a tech startup that raised $500k+ to bring a robust cross-platform mobile app from ideation to production, I understand how to manage roadmaps, deliverables, teams, business plans, and budgets to bring a product to life. Outside the startup world, I've built everything from personal sites to large applications at scale, always with the same attention to detail that end-users, clients, and team members expect. From an implementation perspective, I think designing the correct architecture is critical. You have to start with a solid blueprint and foundation in order to achieve a codebase – and final product – that is intuitive, scalable, and maintainable. While I prefer front-end projects, I am quite comfortable with navigating backend environments as well (particularly NodeJS), and am very familiar with a plethora of API integrations. I've also built countless build scripts, tooling/deployment flows, web-scraping bots, image generation & manipulation scripts, and even interactive Twitter & Discord bots. I also have experience with Solidity, and have written multiple Smart Contracts on the Ethereum blockchain with accompanying client-side code to interact with them, including more than a dozen interactive web3/ethersJS sites. I have a knack for debugging & reverse engineering existing codebases, and enjoy refactoring (when necessary) and cleaning up code to make it more intuitive. Looking forward to working on everything from bite-size weekend projects to full-scale development projects. Solo, small teams, or large – let's build something!
