Full Stack Developer in Typescript (Next.js/Postgres/Docker/Cypress)

About

Senior Full-Stack / Backend, Data & AI Platform Engineer with 12 years of experience building production SaaS, AI-powered applications, distributed systems, data-intensive platforms, and consumer-facing web/mobile products.

Strong hands-on expertise across TypeScript, React, Next.js, React Native, Node.js, Python, PostgreSQL, Supabase, Kafka, Redis, Tailwind CSS, REST/GraphQL APIs, and event-driven architectures. Focused on translating product requirements into intuitive, responsive, polished user experiences while ensuring backend reliability, data ingestion, asynchronous processing, API integrations, and production scalability.

Recent work includes Scholarly / AdmitRaven, a college admissions and mentorship platform across two product iterations; Jukebox, a social music discovery and review app published on the Apple App Store; and MSBAI, where I designed hybrid retrieval across vector, graph, and relational stores at ~250 ms p99 and built long-running AI/HPC pipelines with Kafka, retries, recovery, and continuation. Also experienced with Nference’s Kafka/data-processing work.

Built production AI agents and multi-step LLM workflows using retrieval, tool calling, structured outputs, persistent memory, external AI APIs, human review, retries, and resumable execution. Bring extensive experience with multi-tenant SaaS architecture, database design, authentication, Row-Level Security, RBAC, billing, webhooks, automated testing, observability, and production reliability. Comfortable working directly with founders and small teams, independently identifying product/UX improvements, prioritizing technical work, and owning delivery from ambiguous requirements through implementation, deployment, and production stabilization.
