About
Backend lead at a stealth startup and builder of MailIQ/MailBox—an automated Gmail inbox digest + cleanup system. Designed secure multi-account email ingestion and cost-efficient LLM-based summarization, and implemented robust unsubscribe automation using Playwright + OpenAI webpage analysis (including captcha-handling) with strong safety guardrails, incremental rollouts, and rollback strategies.

Key Strengths
- Designed an email backend balancing speed, privacy, and Gmail policy constraints
- Strong tradeoff-driven architecture decisions (polling vs push; batch vs per-email summarization; automation safety vs coverage)
- Built safety-guarded unsubscribe automation with retries, reversibility, and rate limiting
- API reliability practices: thin endpoints, background jobs, strict schemas, timeouts/retries, health checks, clear error contracts
- Security-first API design: OAuth/JWT, input validation, rate limiting, audit logs, locked-down CORS
- Led low-risk refactors using parallel old/new logic comparison, gradual traffic shifting, and fast rollback
- Improved robustness by identifying real-world unsubscribe edge cases (captcha/login variability) and adding guardrails/fallbacks
- Reported productivity impact: inbox digest + bulk unsubscribe saved ~60% time managing email
