Custom Software Development FAQ

Frequently asked questions

How does a custom software development project start?

Every software project begins with a free technical discovery call. We analyze your architecture, constraints, and business goals, then deliver a detailed project roadmap and technical blueprint within 48 hours, tailored to your system, not a cookie-cutter process.

Who are Dude Lemon's clients?

We have delivered software projects for Fortune 500 companies including Google, Amazon, Philips, Starbucks, and Best Buy, alongside high-growth startups and SaaS companies. Many enterprise engagements run under strict NDAs, so the public site shows only a portion of the work. In a qualified sales conversation we can privately walk through proof of delivery, including shipped applications, project correspondence, and delivery metrics, within the confidentiality limits of each engagement.

What makes Dude Lemon a pioneer in AI-driven app development?

AI is a core engineering discipline at Dude Lemon, not an add-on. We ship production LLM integrations, RAG knowledge bases, AI agents, and conversational commerce systems, each engineered for scale and security with load-tested architecture, strict data boundaries, SOC 2 audited operations, and 99.9% uptime SLAs.

Do you take over and modernize existing codebases?

Yes. We routinely inherit legacy software systems, conduct thorough code audits, and incrementally improve architecture, test coverage, security, and deployment pipelines. We only recommend a full rebuild when the existing codebase genuinely cannot support your requirements.

What technologies and programming languages do you specialize in?

Full-stack software development with React, Node.js, TypeScript, Python, PostgreSQL, AWS, Docker, Wix Velo, Webflow, Shopify app integrations, and AI/ML integrations. Our core strength is building scalable backend architecture, cloud infrastructure, and production APIs that enterprise applications depend on.

Do you build Wix, Webflow, and Shopify apps?

Yes. We build custom Wix Velo applications, Webflow apps and integrations, Shopify apps, storefront customizations, ecommerce automations, subscription flows, checkout extensions, and private operational tools connected to commerce platforms.

Ready to start your custom software project?

We take on a limited number of app, website, web app, Wix, Webflow, Shopify, and custom software development engagements each quarter. Get a free consultation and project proposal within 2-3 business days.
