Building scalable mobile products, full-stack platforms, and AI-assisted engineering workflows that improve delivery quality.
I am a Senior Software Engineer / Technical Lead with 8+ years building mobile, web, backend, and developer-platform systems for enterprise-scale product teams.
- Led 15+ engineers inside 40+ member delivery programs.
- Built and modernized Flutter / React Native applications serving 1M+ active users.
- Migrated a 50,000+ line legacy mobile codebase to Flutter and reduced build time by 20%.
- Improved quality with 90% integration-test coverage, 25% fewer critical bugs, 30% fewer production bugs, and 75% higher POS E2E coverage.
- Built AI-assisted engineering workflows for code review, QA verification, standards-as-code, MCP tooling, and developer productivity.

Portable coding standards and SDLC workflows for AI coding agents.
- TypeScript CLI + MCP runtime for syncing engineering standards into Cursor, Claude Code, GitHub Copilot, Gemini, Kiro, Roo, and Codex-style workflows.
- 259 standards across 20+ frameworks, including Flutter, React Native, Next.js, NestJS, Go, Android, iOS, databases, quality engineering, and specialist agents.
- Runtime enforcement through MCP tools so sub-agents can load relevant standards before editing code.
- Includes release discipline, benchmark reporting, documentation, changelog, generated exports, and workflow compatibility layers.
Public-safe summary of enterprise mobile and full-stack delivery work.
- Led Flutter / React Native architecture for commerce, POS, management, and marketing platforms.
- Built offline-first mobile workflows with NoSQL persistence and native SDK integration through platform channels.
- Applied Clean Architecture, DDD, Bloc, MVVM, dependency injection, CI/CD gates, and release governance.
- Mentored engineers through code review, architecture reviews, testing strategy, and production-readiness checks.
Public-safe summary of internal automation and developer-platform work.
- Built agent-assisted workflows for PR review, acceptance-criteria verification, test-gap detection, Zephyr-linked test generation, LambdaTest report review, and Appium-based mobile verification.
- Measured code-review graph workflows that reduced review tokens by 48%, tool usage by 66%, and review latency by 60%.
- Designed standards-as-code systems so engineering rules are versioned, discoverable, and reusable across AI coding tools.
