💻Custom Software Development

Full-stack development with a focus on data-driven applications, healthcare analytics, and AI-powered tools. I build fast, ship fast, and use modern stacks that scale.

What I Build

Data Applications

Interactive dashboards, data pipelines, and analytics platforms. DuckDB, Polars, D3.js — I choose the right tool for the scale of your data.

• Real-time dashboards with live data feeds
• ETL pipelines and data enrichment workflows
• Custom visualizations (D3.js, chart libraries)

Web Applications

Modern web apps built with Next.js, React, and TypeScript. Deployed on Vercel with CI/CD from day one.

• Full-stack Next.js applications with server components
• Progressive Web Apps (PWA) with offline support
• API development (REST, GraphQL) with Hono or FastAPI

AI & Automation

Custom AI integrations, MCP servers for Claude, and workflow automation that saves hours of manual work.

• MCP server development (Model Context Protocol for Claude)
• NLP pipelines for clinical and business text
• Web scraping and data collection systems

Tech Stack

• Frontend: Next.js, React, TypeScript, Tailwind CSS, D3.js
• Backend: Hono (Bun), FastAPI (Python), Node.js
• Data: DuckDB, PostgreSQL, Polars, Parquet, DuckDB WASM
• AI/ML: Claude API, spaCy, medspaCy, Transformers
• Deploy: Vercel, GitHub Actions, Docker

Pricing

• Small project (landing page, simple tool) — $100–$300
• Medium project (dashboard, data pipeline, web app) — $300–$800
• Large project (full-stack app, AI integration, multi-phase) — $1,000–$2,000

Timeline: 1–6 weeks depending on scope. All projects include source code handoff and deployment.

Recent Work

• PYAAR.Radio — 41K+ track music library with DuckDB WASM, fuzzy search, YouTube/SoundCloud playback
• FDA CRL Analyzer — 202 FDA Complete Response Letters analyzed with DuckDB + Polars
• NBA Match Dashboard — Play-by-play visualization with D3.js shot charts and advanced boxscores
• FDA Devices MCP — MCP server for FDA device classification, 510(k), PMA, recalls, and adverse events

Let's Build Something

Email prahlaad@pyaar.co with what you're looking to build. I'll scope it out and get back to you within 48 hours.

Project-Based

• Milestone-based — Pay per phase (Design → Build → Deploy). Typical split: 25% / 50% / 25%
• Monthly retainer — $300–$500/month for ongoing development, maintenance, and feature additions
• Revenue share — Reduced upfront + small revenue share. Selective — must align with my interests
