└─$ echo "Software engineer at Cognizant, focused on AI. I build LLM-powered products: agents that call tools through MCP, local models with Ollama, streaming chat, and voice assistants with speech-to-text and safety checks. I also created AI Foundation, 93 free interactive lessons on AI engineering."
echo "I came to AI from Android (Kotlin, Jetpack Compose, apps on Google Play), so I care about shipping AI features people actually use. Open to collaborating on AI agents and LLM products. When I'm not coding, you'll find me swimming or playing ping pong."
live93 free, visual lessons on AI engineering: KV cache, prompt caching, RAG retrieval and reranking, tool calling, evals and guardrails. Each pairs a plain-English explanation with an interactive demo, runnable Python and a quiz.
sourceReal-time observability for OpenCode AI agents: a plugin streams tool calls, idle and permission events over SSE, and each agent appears as a pixel-art character moving around an office.
sourceA fully local AI agent: a FastAPI service lets an Ollama model choose a tool from an MCP server, runs it over SSE, and answers from the result. No cloud LLM, no API keys.
sourceA voice-first AI companion for calming down after a stressful moment: Whisper speech-to-text with live captions, an LLM-guided grounding and reframing flow, text-to-speech, and a crisis check on every message.
sourceA Chrome extension that rewrites any text in 9 tones, from polite to persuasive, using Groq, OpenRouter, Claude, ChatGPT, Gemini or Grok. Your API key stays in local storage.
play storeA modern task management Android app built with Clean Architecture and Jetpack Compose that turns your wallpaper into a dynamic to-do list.
liveA ChatGPT-style chat app with streaming replies from Ollama (local), Groq, Gemini or OpenAI, plus Markdown and code highlighting. API keys stay in the browser.
play storeA Kotlin-based Android app for reading and visualizing device sensor data in real time.
liveA local LeetCode-style coding challenge platform supporting Python and Kotlin. Solve algorithm problems in a web editor, run code against test cases, and get instant feedback.
free server: first load can take ~30 s
