About

Full-stack developer who owns reliability as much as features.

Eight-plus years shipping web, mobile and platform products end to end — deep in React, Next.js and TypeScript, with backend work in Nest.js, Node and Python.

I build the structured logging, BigQuery dashboards and alerting that catch authentication failures before users report them, and have worked through tens of production incidents from detection to resolution.

Claude Code, Cursor and Codex are part of my daily loop — and I build the rules, prompt libraries and CI review agents that make AI-assisted development dependable for a whole team.

Focus areas

  • Full-stack TypeScript — React, Next.js, Nest.js
  • Reliability & observability
  • AI-assisted engineering workflows
  • Performance & Core Web Vitals

Timeline

Experience

  1. Senior Software Developer

    Tali.aiAI-assisted clinical documentation platform

    Apr 2023 — PresentCurrent
    • Drove platform reliability with the core engineering team through tens of production incidents — root-cause analysis and fixes — cutting repeat authentication failures by roughly 70%.
    • Built the observability layer for authentication and session flows — custom structured logging, BigQuery dashboards and threshold alerts posted into a dedicated Slack channel — cutting detection of user-facing sign-in failures from hours of support tickets to minutes.
    • Turned ad-hoc escalations into a repeatable incident process — alert routing, triage ownership and follow-up tracking — shortening average time to resolution by about 45%.
    • Use Claude Code, Cursor and Codex daily for generation, refactoring, test writing and prototyping, and built the internal tooling, rules and prompt library that made the workflow repeatable team-wide — cutting typical feature turnaround by around 35%.
    • Shipped AI-assisted code review into GitHub Actions, screening every pull request for security and code-quality issues before human review, and authored Cursor rules encoding the design system so generated UI stays on-system and designers can contribute working interface code.
    • Migrated the platform to Next.js 15 across every breaking change with no customer-facing downtime, cutting first contentful paint by 50%.
    • Built the product applications on an Nx monorepo with Storybook, Playwright coverage and the Segment/Mixpanel analytics pipeline, and moved the marketing site to Webflow so content ships without engineering time.

    DigikalaE-commerce marketplace

    Apr 2021 — Apr 2023
    • Refactored a legacy jQuery product serving 10M users to React, cutting page load time by 40% and removing the recurring downtime the old stack produced.
    • Built an internal component library with Rollup and tree shaking, reducing shared bundle size by about 25% across consuming products.
    • Documented the library in Storybook and drove adoption across multiple product teams, standardizing UI patterns in a large multi-team engineering organization with shared release processes.

  3. Front-end Developer

    Apsy.ioAutomated app-building platform

    May 2019 — Dec 2021
    • Developed a Flask service that automated UI code generation, and supported the AI team by extracting and formatting Adobe XD files into structured JSON.
    • Created the platform's Azure CI/CD release pipeline, replacing manual releases with a repeatable automated process.
    • Shipped a project boilerplate that cut new-project start-up time by 30%.
    • Built the company website in Next.js with incremental static regeneration, extensive animation work and an embedded Adobe XD preview.
    • Designed the online coding interview and offline exam used in the company's hiring process.
