Web App & Custom Tool Development
Transform complex spreadsheets and manual operations into responsive, purpose-built web applications, browser tools, and client dashboards designed for speed and reliability.
Overcomplicated SaaS & Fragile Spreadsheets
Generic SaaS subscriptions lock businesses into costly per-user tiers loaded with unused features, while critical custom workflows are left stranded in bloated spreadsheets that slow down and break under multiple collaborators.
Rigid Off-The-Shelf Software
Forcing your unique business processes into rigid pre-built software leads to workaround scripts and frustrating user experiences.
Escalating Per-Seat Costs
Software licenses accumulate month after month even when your team only needs a fraction of the provided feature set.
Data Silos & Concurrency Issues
Spreadsheets lack robust permission boundaries, validation rules, and transactional integrity when edited simultaneously.
Focused Applications That Solve Specific Tasks
We architect single-page applications and browser utilities that focus on exact user workflows. Fast load times, responsive UI controls, and direct database persistence.
Interactive Client Interfaces
Dynamic, zero-refresh browser interfaces with snappy state updates, instant input validation, and clean navigation.
Admin Portals & CMS Tools
Internal administrative tools for viewing records, managing content, updating settings, and monitoring system activities.
Serverless Backend APIs
Global SQLite edge databases (Cloudflare D1) and object storage (R2) that scale on demand with near-zero idle infrastructure cost.
Included Deliverables vs. Exclusions
Honest technical scopes defined by discrete features and verifiable functionality.
Included in Scope
- ✓ Custom single-page web app architecture & state management
- ✓ RESTful API endpoints with structured JSON schemas
- ✓ Secure authentication, session management & role-based access
- ✓ Responsive UI layout tested on touch devices and desktop displays
- ✓ Database schema migrations, backup logic & rollback verification
Explicitly Out of Scope
- ✕ Native Apple App Store (Swift) or Google Play (Kotlin) compiled mobile binaries
- ✕ 24/7 round-the-clock enterprise level-3 operational monitoring shifts
- ✕ Indefinite feature additions outside agreed milestone specifications
- ✕ High-frequency algorithmic financial trading engines
Process & Communication
Collaborate directly with the lead developer from schema design through staging sign-off.
Data Model & UX

API & State Core
Build serverless API endpoints, database tables, and state management controllers.
UI Integration & Auth
Construct interactive panels, modal controls, authentication cookies, and feedback states.
Staging & Cutover
Automated integration testing, administrative credentials handover, and live deployment.
Working Web Applications
Inspect live web applications engineered and operated on this platform:
- Ninomax Admin CMS & Rollback EngineFull-featured administrative portal with authenticated sessions, draft customizer, R2 media asset pipeline, and D1 version snapshots with instant rollback.
- Interactive Browser Tool SuiteClient-side tools including the AI Visibility Checkup, SEO Cost Estimator, and responsive HTML5 canvas games with sound synthesis and state persistence.
Technology & Security
Lightweight, high-speed architectures engineered for operational stability:
Tech Stack
Cloudflare Pages & Workers, Cloudflare D1 (Serverless SQLite), Cloudflare R2, modern ES6+ JavaScript, and responsive CSS.
Security & Data Isolation
Parameterized SQL statements prevent SQL injection, secure HttpOnly/SameSite session cookies prevent credential leakage, and all file uploads are verified for MIME type and size limits.
