[PRODUCT ENGINEERING SERVICES]

Ship the product your roadmap is asking for.
With zero agency bloat.

KD Studios provides senior product development across three specialized engineering silos. You work directly with Kiavash Davoodi—a senior systems architect in Copenhagen taking unified ownership from product scope to production code.

SILO 01 // MOBILE PRODUCT ENGINEERING

AI-Native iOS & Android App Development

From concept to Apple App Store and Google Play releases. We engineer cross-platform mobile apps with native hardware performance, strict latency budgets, and seamless in-app monetization.

SwiftUI & React Native Expo SDK 52

We build using modern React Native with TurboModules, Fabric renderer, and direct hardware bridges for camera feeds, biometrics, haptics, and background geolocation.

  • Instant camera shutter processing and local image compression
  • EAS Cloud CI/CD for continuous TestFlight and Internal Testing releases
  • Adapty SDK integration for server-driven subscription paywalls

Vision & LLM Mobile Pipelines

AI on mobile requires tight bandwidth and latency budgets. We integrate sub-1.2s multimodal computer-vision pipelines with deterministic fallbacks (e.g., barcode UPC scanning) when visual confidence is marginal.

  • Streaming token outputs with low mobile battery consumption
  • Offline local caching on food/product taxonomy hashes
  • Production-proven in our flagship application Calibite
SILO 02 // WEB PLATFORMS & SYSTEMS

Autonomous Web Platforms & Next.js Architecture

Modern web applications must be fast, resilient, and observable. We architect end-to-end platforms from typed edge routes down to hardened database isolation.

Next.js App Router & Server-First HTML

Eliminate client-side hydration delays and Core Web Vitals penalties. Every public route is server-rendered for instant sub-100ms TTFB and complete SEO crawlability.

  • Server Components with client interactivity pushed strictly to leaf nodes
  • Strict Zod runtime data validation on all API input boundaries
  • Vercel Edge streaming and global low-latency CDN delivery

PostgreSQL & Row-Level Security

Multi-tenant enterprise data requires real database-level isolation, not just application filter guards.

  • PostgreSQL schemas with fine-grained Row-Level Security (RLS) policies
  • Supabase Realtime WebSockets for live bidding, collaboration, and chat
  • Immutable audit logs and transactional event integrity
SILO 03 // VISUAL CRAFT & IMMERSION

3D WebGL & High-Craft Design Systems

Software does not have to look like a generic corporate template. We create bespoke, atmospheric digital products that convert visitors into believers.

GPU-Optimized WebGL & Three.js

Immersive 3D interactive canvases engineered with strict performance guardrails: DPR capped at 1.5, texture memory budgets, and IntersectionObserver pausing when scrolled out of view.

  • Zero CPU/GPU battery drain during background tab or off-screen states
  • Smooth 60fps particle kinematics and custom GLSL shaders
  • Zero layout shifts (CLS < 0.02) with pre-rendered radial fallbacks

Obsidian Glass & Typography Rhythm

Sophisticated dark obsidian surfaces with multi-tier elevation, crisp 1px specular borders, and mathematical typography rhythm (Space Grotesk + JetBrains Mono + Inter).

  • WCAG AA contrast compliance (minimum 4.5:1 ratio) on slate tokens
  • Concentric border radii and optical alignment discipline
  • Spring physics micro-interactions with tactile visual feedback
[ENGAGEMENT MODELS // TWO WAYS TO BUILD]
