Andrew is the best possible thing to happen to our business and the definition of a true professional. I could not recommend him enough. Anyone who has the opportunity to work with Andrew should consider themselves extremely lucky. โ I excel at expertly guiding the app dev process to max out your revenue-earning potential in contrast to your costs, and to steer you away from common SaaS app pitfalls. Client Outcome Examples: โก amzalert.com (8-Figure Acquisition - Rebuilt In 4 Months) โก launchcontrol.us (8-Figure Annual Recurring Revenue - ARR) โก GuestBan.com (Concept-To-Live in 5 Months - 1M+ Monthly App Checkins) My support is based on hard-won successes built through more than a decade of SaaS app obsession. Most of my clients are: โ๏ธ Existing Businesses - Post-revenue โ๏ธ Solopreneurs & Small Teams - Wanting to build an MVP app โ๏ธ Funded Startups - Focused on turning funding into MRR โ๏ธ Existing Early Stage SaaS - Want to rebuild and scale up Iโm the founder of a small, hand-picked team of talented humans. Iโm personally involved in all projects, and we only employ senior developers and native English speakers from the US for project management and communication. My team and I are able to consistently reduce dev costs by about 30-40% by leveraging pre-built development frameworks for common app experiences like the user login or checkout, for example, while reserving valuable dev hours for truly custom functionality. Every project we build delivers: ๐ฑCross Device Compatibility - Desktop - Mobile - Tablet ๐ App Speed Optimization ๐งฉ Scaleable - Cost-Effective Feature Addition Potential ๐ก๏ธ Security ๐ User Analytics & Internal Dashboards ๐ Multi-Language Localization ๐ค Quality Assurance - QA ๐ Paid User Subscription, Billing & Renewal Management Thanks for taking the time to learn more about me.

I build SaaS platforms, AI-powered products, and mobile apps โ from first wireframe to production deployment. 300+ projects delivered across 15+ countries. Whether you need a senior developer for a focused build or a full end-to-end delivery with design, development, and QA โ I scale to what your project actually needs. My strongest work happens at the intersection of product thinking and technical execution. I don't just write code โ I start with documented requirements, define acceptance criteria and edge cases upfront, and deliver against specs you've signed off on. Fewer surprises, fewer "that's not what I meant" moments, and software that works the way you expected. ๐ช๐ต๐ฎ๐ ๐ ๐๐๐ถ๐น๐ฑ: ๐ฆ๐ฎ๐ฎ๐ฆ ๐ฃ๐น๐ฎ๐๐ณ๐ผ๐ฟ๐บ๐ โ Multi-tenant subscription products with real billing complexity: free trials, upgrades with mid-cycle proration, downgrades, failed payment dunning, usage-based plan limits, role-based access control, and admin dashboards with analytics, bulk operations, and data export.

LLM-powered chatbots and automation agents using OpenAI, Claude, or Gemini. OCR and document intelligence for invoices, IDs, and forms. For data-sensitive projects, I deploy self-hosted models (LLaMA, Mistral) on RunPod so your data never leaves your environment.
