Hi, I'm

Dany Arkham

I turn caffeine into high-perf, gorgeous applications across web and mobile platforms. Get bored in React, TypeScript, and Express technologies with 4+ years of suffering to build thoughtful & user-focused applications.

About Me

Frontend & Mobile Engineer | Product Builder | Tech Dad

I'm a Front-End and Mobile Engineer specializing in building real-time applications across three major domains:

  • ZDLTSolana-based ecosystem for funding rate farming, staking, and arbitrage. Web3/Dev platform with real-time order synchronization integrated with Bybit & KuCoin. Focus on reliable platform and professional UX.
  • AIMIIT in-house engineer managing complete tech infrastructure for health & e-commerce ecosystem under AIMI Group: PWA, mobile apps, admin dashboards, inventory systems, and payment integrations. Serving 100K+ monthly active users.
  • BuddyAI companion app focused on daily check-ins and emotional support, with push-triggered follow-ups and a premium subscription model.

My focus is on creating clean, performant interfaces with maintainable codebases. I leverage modern tools like TypeScript, Zustand, Tanstack Query, and WebSocket to deliver production-ready applications that scale.

Fun Fact: I balance multiple full-time roles, crypto projects, and dad life — and still find time to chase weird ideas that might just work.

Why Work With Me

Full-Stack Versatility

Comfortable shipping across mobile, web, and backend services — so projects stay cohesive instead of siloed.

Modern Tech Stack

TypeScript, React/React Native, and pragmatic state/data tools (e.g., Zustand / Query patterns) with a focus on maintainability.

Performance-First Mindset

Performance and UX are treated as product features: smooth UI updates, sensible caching, and careful rendering.

Production Habits

Instrumentation, safe rollouts, and clear error handling — the boring stuff that keeps apps reliable.

End-to-End Ownership

Can take features from spec → implementation → deployment, while keeping communication tight.
