Frontend-heavy full-stack product engineer focused on building complex product UI, reusable frontend infrastructure, and real-time systems with TypeScript, React, Next.js, Node.js, and Python.
I like engineering work where UI, data flow, runtime behavior, and product workflows all matter: editors, dashboards, scheduling systems, trading/runtime tooling, design systems, and performance-sensitive applications.

- Complex product UI: editors, dashboards, scheduling, drag-and-drop workflows, real-time interfaces
- Frontend infrastructure: design systems, reusable component patterns, typed data-access layers, form systems
- State & data architecture: TanStack Query patterns, predictable client state, API boundaries, server/client data flow
- Performance: code splitting, bundle optimization, responsive interaction design, async/runtime optimization
- Real-time systems: WebSockets, task monitoring, exchange/API integrations, health states, recovery flows
- Backend / systems work: Node.js, NestJS, Python/FastAPI, REST/WS integrations, runtime reliability, observability
Private systems project hosted on self-managed GitLab: a Python real-time execution runtime with FastAPI control plane, REST/WS exchange integrations, health monitoring, recovery snapshots, and configurable Liquidity Grid execution policies.
- event-driven task architecture
- health states and emergency pause logic
- snapshot/recovery and warmup flows
- policy-based routing and execution modes
- modify-first order reconciliation
- runtime telemetry and audit logs
Private repository due to proprietary strategy logic. I can share high-level architecture and walk through selected non-sensitive implementation details during interviews.
Worked on an internal platform and AI Proposal Builder, focusing on:
- reusable UI primitives
- Sheet/Modal system
- Form Kit with React Hook Form + shadcn/ui
- typed TanStack Query data-access layer
- calendar and Kanban DnD workflows
- TipTap editor with AI-assisted inline editing
- route/feature-level performance optimization
Worked across frontend and backend systems for internal trading infrastructure:
- React/TypeScript dashboards and task controls
- multi-core Node Worker backtesting workloads
- exchange REST/WS integration layers
- plugin-based strategy tooling
- risk metrics and execution simulation utilities
Personal finance dashboard with bank-like flows, analytics, CSV import, and subscription/payment-oriented product surfaces.
- Next.js / React / TypeScript
- Plaid sandbox integration
- analytics dashboards
- CSV import/export
- subscription-ready architecture

Workspace-based messaging app with real-time communication patterns and collaboration UI.
- React / Next.js
- real-time messaging
- threads and replies
- reactions
- workspaces / RBAC-style flows
