Flutter Engineer · 4+ years · Building apps at scale
Building and shipping features for a retail app with 1.5M+ monthly active users.
| What I Built | Impact |
|---|---|
| Next-gen CMS-driven home screen (Contentful + GraphQL) | 56.7M+ page views (as of March 2026) |
| Shoppable UGC feed (Tolstoy SDK integration) | 1.73M+ video clicks · 5.25% buy-to-detail rate · MAU 1.2M → 1.5M |
From architecture decisions to refactoring legacy codebases — blogs and deep dives coming soon.
Point it at any repo → understand the entire codebase in hours, not weeks.
What it does:
| Feature | How it works |
|---|---|
| 🔍 Module Detection | Auto-groups files into packages/modules by directory structure |
| 🕸️ Dependency Graph | Parses imports across 15+ languages via tree-sitter |
| 💥 Blast Radius | BFS on reversed dependency graph → shows transitive impact of any change |
| 📖 Reading Order | Topological sort → optimal file reading sequence (dependencies first) |
| 🤖 AI Chat | LangGraph agent with 7 query tools, multi-turn conversation with memory |
| 🔎 Semantic Search | ChromaDB vector search on embedded code chunks (RAG) |
| 🔬 Code Review | Multi-stage review: test coverage, blast radius, guidelines RAG, LLM deep scan (OWASP) |
| 🔄 Incremental Reindex | Content hash comparison — only re-embeds changed files, skips unchanged |
| 🧩 MCP Server | 16 tools for VS Code Copilot / Claude Code / Cursor / Codex |
| ⚡ Parallel Embedding | Producer-consumer pipeline — CPU chunking overlaps with GPU embedding |
| 🔄 Execution Flow | Entry points, module-to-module dependency chains with Mermaid diagrams |
Three interfaces, one backend:
| Interface | What |
|---|---|
| MCP Server (FastMCP) | 16 tools — works in VS Code Copilot, Claude Code, Cursor, Codex |
| REST API (FastAPI) | 16 endpoints — /analyze, /chat, /review, /incremental-reindex, /overview, /blast-radius, /reading-order, /execution-flow |
| Web UI (Next.js) | Visual exploration — module browser, diagrams, blast radius viewer, code review, smart reindex |
16 MCP Tools:
| Tool | What it does |
|---|---|
codewalk_analyze_codebase | Scan repo, detect modules + dependencies |
codewalk_scan_files | Batch file listing for smart filtering |
codewalk_submit_filtered_files | Submit relevant files for indexing |
codewalk_index_filtered_files | Embed selected files into vector store |
codewalk_search_codebase | RAG-powered semantic code search |
codewalk_get_module_info | Module details — files, functions, dependencies |
codewalk_explain_function | Line-by-line explanation + blast radius |
codewalk_get_overview | Tech stack, modules, diagram, riskiest files |
codewalk_get_blast_radius_map | Change risk analysis for any file/module |
codewalk_get_reading_order | Dependency-sorted file reading sequence |
codewalk_get_execution_flow | Flow diagram — module-level or file-level |
codewalk_incremental_reindex | Re-embed only changed files (hash-based skip) |
codewalk_refresh_analysis | Re-scan without re-embedding |
codewalk_review_diff | Review git diff — security, bugs, style (LLM + pre-checks) |
codewalk_review_file | Review file against codebase conventions |
codewalk_load_guidelines | Load team coding standards for reviews |
