01Case studies
Engagements delivered for enterprises, from private AI infrastructure to nationwide healthcare and automotive recall portals.
Featured · Private AI Infrastructure
We designed, built, and commissioned a complete on-premise AI datacenter for an enterprise client, then built and deployed a custom AI model to run on it: a dense multi-GPU cluster on a high-speed fabric, redundant power and precision cooling, enterprise security, and a live private model API we develop and maintain, all inside their own walls.
Enterprise Healthcare
A three-year engagement building the US patient portal for a major medical technology brand: identity-matching registration, medical-grade data security, and encrypted audit logs delivered on demand.
Automotive
A secure portal built for a global automotive manufacturer headquartered in Germany during a worldwide steering recall: owners check eligibility by VIN, verify their identity, and complete an encrypted multi-stage registration, hardened against VIN enumeration.
02Enterprise SaaS platforms
Enterprise-grade architecture, zero-downtime deployments, and infrastructure built to handle millions of transactions. Every platform ships with SOC 2 compliance, automated CI/CD, and 99.9% uptime SLAs.
AI sales agent that learns your catalog, answers product questions, captures leads, and hands off to your team. One unified inbox across every channel, plus a mobile app so your team can reply from anywhere.

Stripe
A restaurant point of sale for the floor, the kitchen and the office. Waiters take orders on an app, the kitchen works from a display, guests order by QR code at the table, book online or order for pick-up and delivery run by the restaurant’s own riders, and the back office keeps takings, VAT, stock, staff and the audit log. Ferculon Intelligence reads the restaurant’s own orders, recipes and stock into a daily brief, a seven-day forecast and menu profit, with a person approving every suggestion.
ReactNode.jsPostgreSQLRedisOpenAI
An Uber-style taxi app. Riders book a ride from anywhere to anywhere on the island, the airport included, now or ahead, choose their driver from a list with the price shown, and can book for a guest or a client. Drivers set their own prices, per km or as fixed fares between regions, and start each ride with the rider’s code. Both follow the ride live, chat in the trip and rate each other afterwards, and the rider pays the driver directly in cash or with MCB Juice: alé takes no commission. An operator portal approves drivers, sets cancellation terms and lets hotels and travel agencies book for their guests.

A production multi-vendor marketplace. Independent sellers list against one canonical catalogue, inventory and delivery capacity are committed in a single transaction, and orders fan out into per-seller fulfilments.
Node.jsPostgreSQLOpenAIAWS03Regulated industry software
RecallPilot runs product recalls for manufacturers. Evidr keeps compliance evidence current. Foxborne reconstructs incidents for field robotics teams. We designed and built all three.
Product recall software
When a recall is announced, every affected customer arrives at once. RecallPilot is the recall website they land on and the recall management software behind it: eligibility lookup, registration and claims, notification, batch and lot traceability, and CAPA, connected to your ERP, QMS and MES.
Compliance automation software
Evidr watches every vendor in your stack and raises an alert the moment a breach, vulnerability or incident emerges, scored by severity, mapped to the frameworks it impacts and linked to the source disclosure. Resolve or dismiss each alert with a documented reason, and the audit trail writes itself.
Incident reconstruction software
Foxborne lines up flight logs, companion computer journals and ground receive records from PX4 drones, ground robots and jet-powered UAS on UTC, states the clock error of every source, and hands engineers a report where each line traces back to the original file.

Anything we have not answered here, ask us directly. A senior engineer replies.
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 rather than a cookie-cutter process.
We are a full-service software development company. Our software development services cover mobile app development for iOS and Android, AI development, web applications, websites, Shopify and Webflow apps, APIs and microservices, AWS cloud infrastructure, cybersecurity engineering, security audits, and custom portals. One senior team handles design, build, release, and ongoing support.
Dude Lemon is a remote-first software development company registered in Cheyenne, Wyoming. We work with clients across the United States, the United Kingdom, Canada, and Australia, run discovery calls by video, and deliver in milestones you can review from anywhere. You work directly with the senior engineers building your product, wherever you are based.
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.
Yes. Our mobile app developers build cross-platform iOS and Android apps with React Native and Expo, including the backend and app store release. Our AI developers build production LLM integrations, RAG knowledge bases, AI agents, and Claude integrations such as MCP servers. Both teams work from the same engineering standards and can be engaged for a single project or ongoing work.
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.
Full-stack software development with React, Node.js, TypeScript, Python, PostgreSQL, AWS, Docker, React Native, Webflow, Shopify app integrations, and AI and ML integrations. Our core strength is building scalable backend architecture, cloud infrastructure, and the production APIs that applications depend on.
Yes. We build Webflow apps and integrations, Shopify apps, storefront customizations, ecommerce automations, subscription flows, checkout extensions, and private operational tools connected to commerce platforms.
