Three projects

1. WatchTower

   Describe something on the web in plain words and get one alert when it happens.

   • ~150 test functions across unit, integration, agent, security, end-to-end and load suites
   • 40+ SSRF bypass attempts the URL guard is tested against

   FastAPI, LangGraph, Postgres, Redis, Groq

   Case studyCode ↗Live ↗

2. GridMind

   A spreadsheet where every cell is researched by its own agent, with sources.

   • ~1 LLM call per cell, by design
   • 2 passes at most before a cell gives its best answer

   FastAPI, LangGraph, Svelte 5, Supabase, Groq

   Case studyCode ↗Live ↗

3. CaseCompass

   Describe a consumer dispute and see how Indian commissions decided similar cases.

   • 0.96 MRR on a 27-story airline eval, up from 0.87 with plain vector search
   • 1.00 hit@5 on the same eval: a relevant case in the top five every time

   FastAPI, Next.js, Postgres, pgvector, Jina embeddings

“Thanks @DEVJHAWAR11, this is the right fix. Bounding the send in the shared connection class means every service that connects through _websocket_connect() is covered without touching any of them. …”
