FIELD BENCHMARK / FAST INFERENCE
Codex vs Fast Inference: 1m 52s vs 3m 02s
Real-world latency benchmark generating a full landing page with identical prompts and models.
REAL-WORLD BENCHMARK● VERIFIED RUN · −38% LATENCY
Standard coding agent subscriptions cap out at ~38 tok/s and choke on rate limits. In our head-to-head test using the exact same prompt and model, Fast Inference completed a full production landing page in 1m 52s compared to 3m 02s on default Codex—nearly twice as fast with zero subscription quota cuts.

Mobile systems & utilities
Intro Tools ML PRO
Scaled to 1M+ downloads on Google Play with zero file corruption rate across Android 5.0 to 14+.
Open engineering record
- Problem
- Android 11+ scoped storage restrictions (API 30+) cut off direct filesystem access to game data directories, requiring safe media injection without corrupting user installations.
- Ownership
- Engineered Flutter BLoC architecture, authored custom Storage Access Framework (SAF) platform plugin, implemented Dio HTTP transport with Firebase Remote Config dynamic auth, and instrumented Firebase telemetry.
- Constraint
- DocumentFile tree traversal performance, scoped storage URI persistence, and memory budget during heavy ZIP unarchiving on low-memory devices.
Digital creative studio
Artura Studio
Delivered a luxury cinematic digital experience showcasing global campaigns (Porsche, NVIDIA, Beautiful Destinations, MrBeast) with 60 FPS smooth scrolling and automated catalog sync.
Open engineering record
- Problem
- A cinematic visual production house needed a high-performance interactive web platform to showcase 4K showreels, client case studies, and digital asset licensing without frame stutter or layout shift.
- Ownership
- Architected Next.js 16 and React 19 frontend, engineered GSAP + Framer Motion + Lenis hybrid animation engine, built Supabase repository data layer for dynamic catalog management, and integrated AWS S3 presigned asset delivery.
- Constraint
- High-bitrate video payloads, 60 FPS animation fidelity across mixed-blend viewports, scroll normalization, and sub-second page transitions.
Longevity & biotech
Nova Labs
Shipped high-contrast luxury storefront (novalabs.id) and operations portal (novabio.tech) with real-time biological dosage calculations, zero-loss transaction processing, and multi-tier affiliate tracking.
Open engineering record
- Problem
- A precision peptide research brand required an enterprise commerce platform combining lab COA verification, microgram-precision reconstitution calculators, bilingual localization (EN/ID), automated courier logistics, and multi-tier affiliate commission management.
- Ownership
- Architected full-stack ecosystem: Next.js 16 App Router storefront with BFF API proxy boundary, Zustand state, and Midtrans checkout; engineered Laravel 11 backend with Inertia React control plane, Sanctum auth, row-level inventory locking, and Biteship/Telegram dispatchers.
- Constraint
- Microgram dosage accuracy, strict transactional consistency during high-concurrency checkouts, bilingual SEO routing, and secure session boundary between Next.js BFF and Laravel REST API.
Fintech & F&B operations
InKanteen
Reduced crash rate by 95%, accelerated transaction turnaround by 75%, and stabilized operations across 300+ live school and corporate canteen locations.
Open engineering record
- Problem
- Cashless ordering, QRIS payment settlement, kitchen display dispatching, and thermal receipt printing required synchronization across 300+ institutional canteen locations under peak lunch-hour network constraints.
- Ownership
- Led mobile architecture across Customer (com.inkanteen.customer), Merchant/POS (com.inkanteen.merchant), and Kiosk systems using Flutter BLoC/Cubit, custom Bluetooth ESC/POS printing drivers, Dio HTTP clients, and Firebase telemetry.
- Constraint
- Extreme concurrency spikes during lunch rush, intermittent school Wi-Fi connectivity, low-end kitchen tablet devices, and hardware thermal printer compatibility.
Healthcare & clinical ERP
Audy Dental CIS
Saved 40+ hours/week in manual administrative overhead while maintaining 99% appointment booking accuracy across nationwide clinic branches.
Open engineering record
- Problem
- Indonesia's premier dental clinic network required an enterprise clinical operations system (CIS) to synchronize multi-branch doctor appointments, doctor commission splits, patient tag histories, insurance claims, and multi-tier medical inventory.
- Ownership
- Engineered frontend architecture using Next.js 14, TypeScript, Mantine UI 7, TanStack Query v5, and CASL role-based permissions; implemented appointment schedulers, doctor commission engines, Nivo analytics charts, and Excel clinical ledger exports.
- Constraint
- Multi-branch schedule collision avoidance, granular RBAC matrices across clinical and financial staff, JSON:API response normalization, and high data density medical records.
