## Featured projects

### Concize
- Type: realtime audio
- Product: Concize is a meeting workspace for Indian-language and code-mixed calls. It turns live meeting audio into searchable timelines, cited answers, and follow-up context.
- Implementation: The current path uses authenticated WebSockets, separate transcription and speaker lanes, a sequence-derived session clock, append-only Postgres revisions, deterministic chunks, Postgres lexical search, Qdrant dense retrieval, and SSE cited chat.
- Ownership: Co-developed · backend by me
- Stack: Node.js, TypeScript, WebSockets, PostgreSQL, Supabase, Qdrant, Redis, RabbitMQ sidecar, Python services
- Flow: browser audio -> WebSocket lanes -> revisioned transcript -> Postgres + Qdrant -> cited chat
- Source: https://github.com/rx6ru/Concize/tree/v4

### Trecl
- Type: agent workflow
- Product: Trecl is a company-research agent for targeted outreach. It studies a company, finds useful openings or OSS angles, waits for human target selection, and drafts outreach without auto-sending anything.
- Implementation: A LangGraph fan-out/fan-in sends web research into Qdrant, runs parallel job and GitHub branches, lets a curator rank targets, preserves the human pause in SQLite, and keeps the isolated ReAct GitHub path behind tool and input guardrails.
- Ownership: Solo
- Stack: Python, LangGraph, SQLite, Qdrant, PyGitHub, Pydantic
- Flow: ingest -> parallel job analysis -> GitHub analysis -> human selection -> draft
- Source: https://github.com/rx6ru/Trecl

### IcBerg
- Type: data analysis
- Product: IcBerg is a safety layer between AI agents and databases. It reviews proposed SQL, blocks risky actions, routes approval-worthy changes to a human, and allows bounded read-only analysis when the policy permits it.
- Implementation: The system uses sqlglot recursive classification across reads, writes, DDL, CTEs, and subqueries; fail-safe policy decisions; least-privilege reads; PII redaction; approval-gated writes; hash-chained audit; and SDK, REST-SSE, MCP, and LangGraph surfaces.
- Ownership: Solo
- Stack: Python, SQLGlot, Policy engine, PII redaction, Hash-chained audit, REST-SSE, MCP, LangGraph
- Flow: SQL proposal -> classify risk -> policy gate -> approval or read path -> audit event
- Source: https://github.com/rx6ru/IcBerg

### Strata
- Type: agent memory
- Product: Strata is a portable memory system for coding agents. It gives agents and humans one durable project record without mixing namespaces, leaking secrets, or rewriting history.
- Implementation: It uses append-only records, schema and policy checks, content hashes, namespaces, secret rejection, supersede/relocate/split/merge events, export/restore, and CLI, REST, MCP, and skill-pack surfaces for verified handoffs.
- Ownership: Solo
- Stack: Python, MCP, REST, Append-only records, Policy checks, Agent context, Verification checks
- Source: https://github.com/rx6ru/strata

## Additional builds

### Wombat
- Product: Wombat is an API-key vault for teams that need scoped access without exposing raw provider secrets. It handles ownership checks, encrypted storage, rate limits, validation, and documented API contracts.
- Ownership: Co-developed · backend/security by me
- Source: https://github.com/rx6ru/Wombat

### Saturday
- Product: Saturday is a voice search tool for codebases. It indexes a repository, connects a voice assistant to a local webhook, and lets a developer ask spoken questions while working.
- Ownership: Co-developed
- Source: https://github.com/rx6ru/Saturday

### Reclaym
- Product: Reclaym is a UPI AutoPay recovery engine for failed subscription payments. It receives payment events, deduplicates retries, applies deterministic recovery policy, and reconciles payment-state changes.
- Ownership: Solo
- Source: https://github.com/rx6ru/Reclaym

### Headless Ghidra MCP
- Product: Headless Ghidra MCP is a native inspection bridge for reverse-engineering workflows. It exposes Ghidra analysis, decompilation, imports, exports, call graphs, JSON output, pagination, caching, and safer path handling.
- Ownership: Co-developed
- Source: https://github.com/QuiteArpit/HeadlessGhidraMCP
