I’m a full stack web developer with 10+ years of experience building business web applications end to end—from turning written requirements into working products (data model, APIs, and the screens people use) to shipping safely in stages. My work has been especially strong in React and TypeScript, Node.js services, and Python, typically backed by PostgreSQL and deployed on AWS. I enjoy the less visible parts of engineering that make products reliable and fast: hardening third-party integrations against timeouts and malformed payloads, designing durable workflows for partial failures, and improving performance as data grows through query-plan analysis, indexing, and targeted caching. I collaborate closely with product and non-technical stakeholders to plan releases that start small and scale responsibly.…I’m a full stack web developer with 10+ years of experience building business web applications end to end—from turning written requirements into working products (data model, APIs, and the screens people use) to shipping safely in stages.

Work Experience

Software Engineer at Privy

January 1, 2026 - Present

Build customer-facing features end to end in React and TypeScript, Node.js services, and PostgreSQL, taking work from technical design through production release on AWS. Break broad product requirements into data-model changes, API contracts, screen behavior, and failure cases, then ship improvements in stages with product and engineering. Harden third-party integrations with retries, clear logging, and bounded failure handling. Identify and fix endpoints that slow down as data grows using PostgreSQL execution plans, adding the right indexes and cache where data is read far more than it changes.

Lead Full Stack Engineer at Manifold.xyz

June 1, 2021 - March 1, 2026

Led full-stack engineering for creator and collector products, owning technical decisions across React/Next.js, Node.js, and PostgreSQL. Converted incomplete product ideas into technical designs and staged rollouts while collaborating remotely with product and design. Built reusable React hooks and components around backend APIs and async state to avoid duplicated logic. Designed a transaction workflow with durable states, idempotency, and reconciliation so partial failures recover without duplicate transactions. Improved API performance from multi-second responses back toward sub-second by analyzing query plans, adding composite indexes, removing N+1 patterns, and using selective Redis caching.
