• TokBurn — Developer Tooling · github.com/lsvishaal/tokburn
  Built and published CLI tool that parses Claude Code's local JSONL session files to surface token waste patterns and cost attribution via a FastAPI dashboard. Zero external API calls — fully local.

  • Launch post hit 67K+ views on r/ClaudeCode; featured in Awesome Claude Tools. Community user analyzed 1,765 sessions revealing $5,209 equivalent API cost — the data story drove adoption.
  • Handles edge cases in Claude Code's session format across versions; published on PyPI (pip install tokburn). Zero external API calls — fully local analysis.

• Document Intelligence System — RAG Pipeline · github.com/lsvishaal/constructure-rag
  Built production RAG pipeline for construction document Q&A with source citations.

  • Designed hybrid retrieval system (vector + BM25 + Reciprocal Rank Fusion) to balance recall vs latency. Handles exact code/identifier matching that pure semantic search misses. Hybrid retrieval completes <100ms; full Q&A responses 5-10 seconds with local LLM inference
  • Optimized ingestion with structure-aware chunking (300 words, 75-word overlap) achieving 30 pages/sec throughput. Reduced multi-document processing from hours to minutes, enabling practical production deployment
  • Production-hardened with LRU query caching (1hr TTL), Docker Compose deployment, structured logging, and comprehensive test suite. Cached queries return in <10ms

• Multi-Agent Code Review System — LLM Orchestration · github.com/lsvishaal/Lyzer_PR_Review
  Automated code review using LLM orchestration to catch issues humans miss in initial reviews.

  • Designed 4-agent architecture (logic, readability, performance, security) with specialized responsibilities and parallel execution. Each agent independently analyzes code changes, with deduplication and severity-based aggregation to consolidate findings across domains
  • Achieved high-precision security analysis using specialized prompts grounded in OWASP Top 10 and CWE standards. Validated on real-world GitHub PRs with structured output enabling human-in-the-loop review workflows
  • Integrated with GitHub API for live PR reviews and standalone offline analysis via raw diff input. Supports multiple programming languages with automatic language detection and binary file filtering
  • Production-grade observability: Structured JSON logging with request tracing, Prometheus metrics (request rate, latency, error tracking), Grafana dashboards, Docker Compose orchestration across 5 services with health checks and non-root execution. 60+ unit and integration tests covering agents, diff parsing, GitHub API client, and endpoints

• AstroHomes — Real Estate Platform (Live) · astrohomes.in
  Built production platform for property management startup, enabling non-technical client to manage 50+ listings without code changes.

  • Designed JSON-driven CMS enabling non-technical client to manage 50+ properties independently. Reduced update cycle from 30 min to 6 min (80% faster), eliminating scaling bottleneck
  • Implemented responsive design with accessibility compliance (WCAG 2.1 AA). 95+ Lighthouse scores, ensuring usability on rural connections and older devices
  • Built analytics dashboard tracking performance, traffic, and conversions. Client used insights to optimize portfolio focus on top revenue-driving properties
