About

Senior Full Stack Software Engineer with 6+ years building scalable SaaS and fintech platforms end-to-end. I work across TypeScript, React, Next.js, Node.js, and NestJS, with a strong focus on the distributed systems behind them — Kafka, BullMQ, gRPC, PostgreSQL, Redis, and AWS. I turn complex business requirements into reliable, high-performance software that holds up under real-world load.

Projects

2026

Cartup Limited→Senior Full Stack Developer

A large-scale, distributed e-commerce platform built to absorb flash-sale traffic spikes, bulk catalog mutations, and the full order lifecycle without dropping a beat. I owned the system's most performance-critical paths end-to-end, a 100K+ SKU ingestion pipeline on BullMQ workers with S3 streaming and backpressure, an event-driven product sync fabric on Kafka, and a constellation of gRPC microservices for inventory, seller validation, vouchers, and logistics — and shipped the React + NestJS seller and admin dashboards that operators run the business on every day.

FundedNext→Senior Frontend Developer

A global proprietary trading platform that evaluates traders and provides funded accounts to qualified candidates across forex, indices, and commodities. I shipped core frontend systems — WebSocket-driven real-time market dashboards, TOTP-based MFA, KYC/AML onboarding via Sumsub, and multilingual support across 5+ locales — and drove compliance-sensitive workflows including server-side PDF certificate generation.

Dorik AI→Backend Developer (Node.js)

A no-code website builder with a public GraphQL API that integrates with Zapier, Notion, and Google Docs. I designed and scaled the developer-facing API surface — OAuth2, token-based rate limiting, fault-tolerant error contracts — cut third-party integration time by 40%, and stood up Datadog-based observability that sustained 99.9% API uptime under daily developer traffic.

Open Source

Luma UI→Contributor

An open-source, accessible Tailwind CSS component library for marketing pages, e-commerce surfaces, and application UI. Built with Next.js, Tailwind, and MDX, with a focus on composable primitives and clean DX for downstream consumers.
