Hire the Best Composable Application Developers

Have an app idea but not sure where to start? A few years ago, I was sitting exactly where many of my clients are today: trying to turn an idea into an app. After years of mistakes and learning to code, I ended up building SchooLinks, which grew into an Inc. 5000 business and raised over $90 million. Since then, I focus on designing and developing apps for founders and entrepreneurs with no technical background. People who have identified a problem that an app could solve, but they don't know how to build it. They have the vision, but they don't have the tech partner. And these are the results my clients have gotten: • $350M+ raised by clients • 2M+ users across products built • 10K+ five-star reviews across products built • Top 1% in App Design & Development on Upwork Book a consultation with me today! I’ll save you months of frustration by helping you understand the ins and outs of bringing an app to life: How much it costs, how long it takes, what’s the process and more. The apps I’ve built usually come in the form of: SaaS platforms, internal platforms, Mobile & web apps, Marketplace apps. Trusted By: Harvard, Samsung, Indeed, Yamaha, University of South Florida, and more. Technologies: OpenAI, Claude, Gemini, Flutter, Node.js, Angular, AWS, MongoDB, Figma If you’re serious about building your app the right way, let’s talk!

Senior Full Stack & Blockchain Engineer with 15+ years of software development experience and 7+ years building blockchain products, dApps, smart contracts, APIs, and scalable systems. I help startups and SaaS teams build complete products — not just isolated features. That means I can own the full technical flow from frontend and backend to cloud infrastructure, blockchain integration, smart contracts, and production deployment. Most Web3 products need more than a smart contract. They need reliable APIs, clean databases, secure integrations, responsive interfaces, cloud deployment, and architecture that can scale after launch. That is where my full-stack background becomes valuable. I’ve delivered software for startups and enterprise teams, including projects associated with schoolOS, NFL Rivals, TMZ, DirecTV, TSR, Geeked Out Basketball and Coke Studio. What I can help you build: • Full-stack SaaS platforms • Web3 applications and dApps • Smart contracts using Solidity and Rust • DeFi, NFT, token, and wallet-based systems • Scalable backend APIs using Node.js • REST and GraphQL API development • React and Next.js web applications • Cloud-based architecture and deployment • MVPs from idea to production • Existing product rebuilds, upgrades, and scaling Why clients work with me: ✔ 15+ years in software development ✔ 7+ years in blockchain and Web3 ✔ Strong full-stack experience since 2009 ✔ Backend-first thinking with product-level ownership ✔ Ability to connect Web2 systems with Web3 infrastructure ✔ Clean code, clear communication, and milestone-based delivery ✔ Long-term support after launch ✔ Comfortable with Jira, Trello, Asana, Slack, Teams, Clickup, Basecamp, GitHub Projects, GitLab, Azure DevOps, and milestone-based delivery Core technologies: Core Technologies: Backend & APIs: Node.js, Express.js, REST APIs, GraphQL, Microservices, WebSockets, API Integrations Frontend & Full Stack: React, Next.js, JavaScript, TypeScript, SaaS Platforms, Admin Dashboards, Web Applications Blockchain & Web3: Solidity, Rust, Smart Contracts, dApps, DeFi, NFTs, Token Systems, Wallet Integrations, Web3.js, Ethers.js Cloud & DevOps: AWS, EC2, S3, Lambda, RDS, CloudFront, Route 53, IAM, Docker, CI/CD, Server Deployment, Cloud Architecture, Scalable Infrastructure Databases: PostgreSQL, MongoDB, MySQL, Firebase, Database Design, Query Optimization Product Delivery: MVP Development, System Architecture, Production Deployment, Performance Optimization, Long-Term Maintenance Whether you are building a SaaS platform, launching a dApp, creating a smart contract system, or scaling an existing product, I can help you move from idea to production with reliable engineering and clear execution.
