WinTechnology started as a software development firm in 2003 — we've shipped web applications, mobile apps, and custom software through every major technology wave since then: Ajax, mobile-first, cloud, API-first, and now AI-native. We know what lasts and what doesn't.
Today we build AI-integrated web applications, cross-platform mobile apps, and custom business software for Southern California companies that need software built for the specific way their business works — not a configuration of someone else's template.

WinTechnology Inc. provides custom web and mobile app development services across Southern California, including Corona, Riverside, Temecula, Murrieta, Moreno Valley, Anaheim, Irvine, and the greater Inland Empire. Our Corona CA office at 2621 Green River Rd has served the region since 2003.
Applications that solve real business problems — not prototypes, not MVPs that need to be rebuilt, not systems that only work for the demo. Every engagement is scoped with the full production lifecycle in mind from the first conversation.
Full-stack React and Next.js applications: customer portals, internal tools, dashboards, marketplaces, and SaaS platforms. Server-side rendering for SEO, edge-deployed for performance, designed for the users who'll actually use them — not the stakeholders who'll demo them.

iOS, Android, and React Native cross-platform applications. MVP launches, enterprise mobile platforms, and field apps for the contractors, property managers, and service businesses that dominate Southern California's economy. Tested on real devices before they ship.
iOS · Android · React Native · Expo
LLM integrations, intelligent search, predictive recommendations, document processing, computer vision, and natural language interfaces built into your application — where AI adds genuine value rather than surface-level novelty. We scope the AI layer the same way we scope everything else: by the outcome it needs to produce.
OpenAI · Claude API · LangChain · Vector DB
RESTful and GraphQL APIs that connect your systems. Third-party integrations — payment processors, CRMs, ERPs, logistics APIs — internal service meshes, and event-driven architectures that let your business tools talk to each other reliably.
REST · GraphQL · Webhooks · Event-Driven
Custom Shopify builds, headless commerce platforms with Next.js frontends, B2B e-commerce systems, and subscription and recurring billing platforms for retailers and direct-to-consumer brands in Southern California's massive consumer market.

Ongoing development retainers, performance optimization, dependency updates, security patches, and new feature releases. Long-term technical partnership with one team that knows your codebase — not a rotating support queue that reads the ticket with fresh eyes every time.

No feature lists without context. No wireframes before we understand the business. Every engagement starts the same way: we learn how you work before we suggest how to build.
We start by understanding your users, your existing systems, and the business outcomes the application needs to deliver. Not wireframes first — context first. This is where most development projects fail, so it's where we spend the most time.
We design the technical architecture, choose the right stack for your requirements and team, and deliver a scoped proposal with timeline and fixed pricing by milestone. You know the full cost before a line of code gets written.
Two-week sprints with working software at the end of each. You see progress, give feedback, and own the repository from day one. No black-box builds that surface fully-formed six months later and miss half the requirements.
We deploy to your infrastructure — cloud, dedicated, or managed — document the system thoroughly, and train your team. The code is yours, completely and without qualification. Ongoing retainers are available, but never required.
We choose the stack based on your requirements — not on what we happen to prefer this quarter. These are the tools we use in production daily, and we can explain every choice plainly.
We don't force every project into the same stack. The right tools depend on your team's capabilities, your scale expectations, and your long-term maintenance reality. We explain every architectural decision in plain language.
Based in Corona, CA — we work with clients throughout Southern California. Most development work happens remotely, but in-person discovery workshops and sprint reviews are available at our Green River Road office for clients who value face-to-face collaboration.
WinTechnology's home since 2003. In-person meetings available at our Green River Road office — discovery workshops, sprint reviews, and launch meetings.
Learn MoreUC Riverside's innovation ecosystem and Riverside's diverse economy create strong demand for custom software. Healthcare, logistics, education, and professional services — all active markets.
Learn MoreTemecula's rapidly growing business community needs software that scales with them. Healthcare, hospitality, wine country tourism, and professional services all served from our Inland Empire base.
Learn MoreMurrieta's healthcare and professional services businesses frequently need custom portals and workflow software. HIPAA-compliant applications, client portals, and field tools for a growing suburban economy.
Learn MoreDevelopment projects raise real questions about cost, timeline, and ownership. Here's how we answer them — plainly.
Start a ConversationCustom web application projects typically range from $15,000 for focused internal tools to $150,000 and up for enterprise platforms. WinTechnology uses fixed-price milestones — you know the cost before development starts, not after. Contact us for a scoping call and written proposal based on your specific requirements.
A focused React Native MVP typically takes 10 to 16 weeks from signed scope to App Store submission. Native iOS or Android apps with more feature complexity run 16 to 24 weeks. Timeline depends on feature scope, third-party integrations, and App Store review cycles.
Yes. WinTechnology integrates LLMs (OpenAI, Anthropic Claude), vector search, computer vision, and predictive models directly into web and mobile applications. AI features are scoped based on where they create real business value — not added for novelty or to justify a higher project fee.
You own everything. WinTechnology delivers full source code, documentation, and repository access to clients at each milestone. There are no licensing fees, no lock-in, and no dependency on us to maintain your own software — unless you choose an ongoing retainer for continued development.
Yes. WinTechnology offers monthly development retainers covering performance monitoring, security patches, dependency updates, and new feature releases. Many clients start with a project engagement and move to a retainer — one team that already knows the codebase is worth more than a fresh support queue every time something needs attention.
We offer a free scoping call for development projects — 30 to 45 minutes to define your requirements, identify technical risks, and determine whether a custom build is the right path versus a configured solution. Honest assessment, no upselling.
