Whether you need to launch an MVP, add a feature, integrate an API, or fix an existing application, I can help you move your project forward. My background combines hands-on development with technical leadership on enterprise software projects. I also build and maintain my own products, including LingoKey, an iOS translation keyboard. That means I understand the work beyond writing code: making features useful, handling platform requirements, managing infrastructure costs, and keeping a product running after launch. What I can help you with: • Web applications & backend development: Customer-facing websites, SaaS applications, admin dashboards, internal tools, and APIs using React, Vue, Next.js, Node.js, Python, and Java/Spring Boot. • Mobile app development: Native iOS development with Swift and cross-platform apps with Flutter, including authentication, subscriptions, API integrations, and platform-specific features. • Cloud infrastructure & deployment: AWS and Cloudflare backends, serverless applications, database integration, Docker, and CI/CD pipelines. I can help set up new infrastructure or troubleshoot an existing deployment. • AI feature integration: Connecting AI models to your application for translation, text processing, and other practical workflows, with attention to response quality, latency, and usage costs. How I approach projects: I start by understanding the outcome you need and the constraints we’re working within. From there, I focus on a practical solution with a clear scope—not unnecessary complexity. You can expect straightforward communication, maintainable code, and clear handover documentation. I’m comfortable working independently on a defined task or collaborating with your existing team, and I’ll raise technical risks and trade-offs early. I’m available for part-time collaboration, individual features, bug fixes, and ongoing product development. Tell me what you’re building, what’s already in place, and where you need help. less -
