PROFESSIONAL EXPERIENCE

Lead Frontend Developer — DeepXFeb 2024 – Present
Progressed from Frontend Developer to Lead Frontend Developer as the sole frontend engineer on a cross-functional team
(backend, QA, design, business analysts, ML/CV engineers), reporting directly to the team lead/CTO.
• Owned frontend architecture and delivery end-to-end across a portfolio of 7+ production-grade applications, including
video analytics, live monitoring, and AI-assisted operational workflows.
• Built React interfaces for real-time video analytics, including low-latency live streaming, multi-month CCTV archive
playback, AI-assisted object detection/tracking workflows, and dashboards aggregating video events, alerts, and
telemetry across multi-level facility deployments (4–7 camera feeds per site).
• Integrated frontend applications with REST APIs, WebSocket-based real-time data streams, blockchain services, smart
contracts, and cryptocurrency payment systems.
• Designed and maintained a shared NX monorepo (Feature-Sliced Design) for the two most complex products — the
core platform and the Web3 consulting platform — with shared domain libraries and reusable UI packages; additional
products were built as standalone applications following the same conventions.
• Established development standards and reusable application patterns adopted across the team's other frontend
projects, working directly with the CTO/team lead on architecture decisions.

Backend Developer Intern — ProductCraftersMay 2022 – Aug 2022
• Built RESTful APIs, PostgreSQL integration services, and validation/error-handling middleware using Adonis.js.
• Contributed to API documentation and gained hands-on experience with backend architecture and request-lifecycle
management.

PERSONAL PROJECTS
Independent Full-Stack Projects (JavaScript/TypeScript) — Aug 2023 – Feb 2024
• Built independent full-stack projects outside of paid work to deepen end-to-end development skills — responsive
frontend UIs, REST APIs, and database-driven features using JavaScript and TypeScript.
PROJECTS
AI & Blockchain Platform for Consulting and Project Management
• Led frontend development of a full-cycle AI-powered SaaS platform for consulting, project management, and
workflow automation, within an NX monorepo using Feature-Sliced Design.
• Built dashboards, project management workspaces, and client-facing interfaces, integrating REST APIs, AI-powered
services, and blockchain functionality via TanStack Query, wagmi, and viem.
• Established a reusable UI system based on Radix UI, role-based access control, and shared state management
architecture, collaborating closely with backend engineers, product, and design.
Web Application for Review of LLM-Processed Medical Documents
• Progressed from frontend contributor to lead developer on an AI-powered platform for reviewing, validating, and
correcting LLM-processed medical documents.
• Built document review workflows combining PDF rendering with structured data validation, and designed
schema-driven form systems for verifying AI-extracted medical information.
• Integrated real-time processing updates via WebSocket and built operational dashboards for workflow monitoring,
collaborating closely with QA, backend, and AI teams.
Web Applications for Mining Company Performance Tracking
• Developed frontend solutions for a suite of industrial monitoring and video analytics platforms focused on operational
visibility, historical data analysis, and AI-assisted event investigation.
• Implemented video playback with detection overlays, event visualization, and timeline-driven navigation across CCTV
archives spanning multi-level facilities (e.g., 4–7 camera feeds distributed across floors per site).
• Built dashboards and workflow management interfaces, optimizing application performance for data-heavy scenarios.
