Amandeep Singh
I build high-performance apps and websites, mostly for small businesses, using Flutter, Next.js, and Cloudflare Workers.
I am a self-taught software developer based in Patiala, India, building full-stack applications and mobile products since 2022.
My current stack focuses on Flutter and Kotlin for mobile, Next.js for web, and Cloudflare Workers with Supabase or Firebase for backend.
Currently, I am also studying Fintech & AI online at Amity University to expand my capabilities in modern financial technology.
Skills & Stack
Edge of Sound
Amandeep Singh
Flutter & Native Android
I build cross-platform apps in Flutter with Kotlin platform channels for deep OS integrations like background audio, camera, and biometrics. I write native Android apps in Kotlin with Jetpack Compose.
Proof
Musio runs background audio with <50ms buffer latency; Shlf syncs 12,000+ books with zero data-loss on network restore.
Creative Web Development
I design & engineer fast responsive pages.
Next.js & TypeScript
My web work starts with Next.js App Router. I handle SSR, SSG, ISR, and static export depending on hosting constraints. UI is built with Tailwind, Framer Motion for micro-animations, and Three.js for immersive experiences.
Proof
ToonStream loads in 0.8s on edge, serves 5,000+ monthly users from Cloudflare edge nodes with no origin server.
$ npm run start:edge
✔ Hono edge API ready on port 8787
➜ POST /api/v1/reply - 200 OK (28ms)
ℹ Cache status: HIT (edge-01-delhi)
✔ D1 database replica synced in 14ms
Cloudflare Workers & Edge APIs
I use Cloudflare Workers with the Hono framework for ultra-low-latency edge APIs. Data lives in Cloudflare D1 (SQLite), KV for caching, and R2 for storage — no cold starts, globally distributed by default.
Proof
ReplyGeniusAI processes 1,500+ AI emails/day with a 1.2s median AI response time running entirely on Cloudflare's edge.
Gemini & LLM Pipelines
I integrate Google Gemini, OpenAI, and open-source LLMs into products using RAG pipelines to constrain outputs. I focus on practical AI — tools that save measurable time, not demos that hallucinate.
Proof
ReplyGeniusAI saves users 4 hours/week on email. RAG context from business FAQs reduced hallucination rate to near zero.
