01Earshot
AI agents
A terminal coding agent built around explicit scope, deny-first permissions, steerable tasks, and persistent session context. A shared agent loop powers the inline terminal UI, headless execution, and editor integrations. Extensible through MCP, skills, hooks, and subagents; currently in public beta.
02Sparebar
Products
A Claude Code companion that places a clearly labelled sponsor line in the time an agent spends working. Built around reversible CLI setup, an advertiser campaign flow, payment webhooks, and an append-only earnings ledger. Currently invite-only, with developer payouts manually reviewed during beta.
03PaisaTrack
Products
A personal finance PWA that turns plain-English expenses into categorised transactions, with budgets, trend analytics, and recurring-subscription detection. Its tool-grounded Q&A lets the model select data slices while the server performs every calculation. Built as a single-user app.
04toolharness
Developer tools
An open-source evaluation harness for tool-call reliability in coding agents, including Claude Code, Cursor, and Codex. Scores eight failure modes using deterministic detectors and an independent LLM-judge layer. Includes BFCL validation, JSON reports, an HTML dashboard, and a CI regression gate.
05China Bazar POS
Business systems
An offline-first Windows retail system replacing a legacy VB6 and MS Access application. Covers 12 modules for four stores, including billing, inventory, purchasing, loyalty, and shifts. Includes double-entry accounting, 50+ PDF and Excel reports, barcode scanning, and Argon2id authentication.
06pgvec-studio
Developer tools
A local-first visual explorer for pgvector embeddings in PostgreSQL. UMAP projection turns vectors into a 2D map, with k-NN similarity search, metadata filtering, and cosine-similarity inspection to understand how the data relates.
07Research Agent
AI agents
An autonomous research assistant that plans searches, gathers sources through Tavily, and synthesises reports. Qdrant provides vector memory; server-sent events stream progress, and completed reports can be exported to PDF.
08PromptSH
Developer tools
A natural-language command shell with OpenRouter translation, local Ollama autocomplete, a dynamic command registry, and session history. Generated commands pass through a whitelist and dangerous-pattern checks before execution.
09Rahi App

A backend project covering authentication, role-based access control, rate limiting, Redis caching, product CRUD, mail, and payment integration.
12AI Pantry Tracker
Products
A pantry manager with ingredient tracking and AI recipe suggestions. Built during the Headstarter fellowship using Next.js and Firebase.
