Product development studio
Authentication, database, payments, deployment, store submission. Built end to end, and live on handover.
Capability
01
Multi-tenant applications with subscriptions, tiers, and usage limits enforced server-side.
02
Native Android, store-ready. Billing, offline capability, and release management included.
03
Model integration, prompt architecture, streaming responses, and generation quotas that hold up under load.
04
Checkout, webhooks, entitlement grants, upgrades and cancellations. Wired correctly, not approximately.
05
Fast, indexable, and built to convert. Analytics and event tracking configured from day one.
06
Dashboards, integrations, and the unglamorous systems that remove manual work.
What complete means
01
Working authentication, a real database, server-side permission checks. Not a front end waiting for someone else to finish it.
02
Payment provider integrated, webhooks verified, entitlements granted automatically. The part most builds quietly skip.
03
Deployed, domain configured, environment variables set. Store submission included where it applies.
Selected work
Web, Android, and everything between the database and the checkout.
Invoicing, contracts, quotations and an AI assistant sold as separately subscribable modules with a team tier. Signature-verified payment webhooks handling seven event types.
Full document toolset with metered anonymous use, account-based quotas and an unlimited paid tier. Limits enforced server-side, not in the browser.
Upload, scoring, ATS evaluation and AI rewriting behind a mixed pricing model: one-time passes alongside a monthly plan.
Category-based generation with tiered limits, DOCX export and premium templates. Shipped to web and Android from a shared product spec.
Workout and nutrition planning with progress tracking, offline-capable free mode, and a subscription unlocking unlimited coaching. Regionally localised pricing.
