Mukhriddin S.

Full-stack engineer, ~5 years. I build and run multi-tenant SaaS on Next.js + Supabase, and integrate LLMs into production web apps.

What I ship:

Tasker — live multi-tenant SaaS I built and run solo. Next.js 16 App Router + Supabase (Postgres, RLS, GitHub OAuth, Realtime). Per-tenant isolation with row-level security, credentials encrypted AES-256-GCM, daily sync on a GitHub Actions cron, and a Manifest V3 Chrome extension on the same backend.

ieltstify — Next.js + Supabase mentor marketplace. Per-tenant routes, username namespacing.

IoT security platform — sensor dashboards, live camera feeds (HLS/WebRTC), interactive maps, workflow automation, LLM integrations.

Logistics — ELD device dashboards, truck route mapping, driver event tracking, Stripe payments with webhooks.

Stack:
TypeScript (strict), React / Next.js App Router, Node.js
Supabase / Postgres — schema design, migrations, RLS policies, incremental sync
Tailwind CSS, Vue / Nuxt
Data viz — Recharts, D3, GSAP
Maps — HERE Maps, Leaflet

AI / LLM in production:
Vercel AI SDK — agent chat, streaming, structured outputs
Agentic workflows with LangChain, LangGraph; tracing with LangSmith
Cloud (Claude, OpenAI) and local models (Ollama, llama.cpp)
Tool-calling pipelines, chat interfaces, AI-powered dashboards
