Onyx — E-commerce Marketplace (Frontend)

Next.js · React 19 · TypeScript · Tailwind CSS · TanStack Query · NextAuth · Zustand · Cypress

• Built customer-facing marketplace with product listing, detail pages (variants, reviews, carousel), search, category/brand browsing, and add-to-cart with quantity/variant selection.
• Implemented multi-step checkout (shipping, billing, payment options, lender/plan selection) and order confirmation with protected routes and session handling.
• Developed user account flows: profile, orders, credits, notifications, address book, security and payment settings, and review management.
• Delivered sales-agent portal with dashboard, transactions, commission wallet, performance/targets, support & disputes, and notifications.
• Integrated auth (login, registration by user type, forgot password, OTP) and onboarding (e.g. “become a sales agent”) using NextAuth and form validation (React Hook Form + Zod).
• Architected shared UI with Radix primitives, Framer Motion/GSAP, and reusable components; used TanStack Query for server state and Zustand for client state.
• Added E2E coverage with Cypress (smoke/full suites) and CI via GitHub Actions; implemented sitemap and robots for SEO.

Lead development of a full-stack AI-powered marketing & CRO SaaS: architecture (Turborepo monorepo, Prisma/PostgreSQL, Stripe, Google Ads), AI agent design (LangChain/LangGraph, OpenAI & Gemini), and product delivery from auth and billing to analytics and AI chat.

• Architected and led implementation of the full-stack platform: Turborepo monorepo (Next.js 16, shared UI package), Prisma/PostgreSQL with vector support, NextAuth (email/phone, roles, team invites), and Docker-based local dev and database setup.
• Designed and built the AI marketing assistant (“Omo”): LangChain/LangGraph workflows, OpenAI and Google Gemini integration, streaming chat, tool-calling for Google Ads data, and CRO-focused system prompts and guardrails.
• Owned Google Ads integration end-to-end: OAuth, data sync (campaigns, keywords, audiences, performance), analytics dashboard (charts, tables, metrics), and AI-generated optimization recommendations backed by live account data.
• Drove subscription and monetization: Stripe integration (plans, trials, renewals, invoices), usage tracking, and transactional email (Resend + React Email) for onboarding, OTP, and subscription lifecycle.
• Defined technical direction for AI features (agent vs simple chat, tool design, context injection) and ensured consistency across chat, analytics, and recommendations.

• Architected and led front-end development for an AI-driven CRO optimization chat web application using Next.js and a component-driven architecture.
• Pivoted the app from front-end only to full-stack by implementing Next.js server actions and API routes, plus backend integrations, broadening my skills in server-side logic, data handling, and end-to-end feature delivery.
• Created a reusable component library and developer patterns that reduced development time by 20% and improved cross-team consistency.
• Implemented automated testing, CI pipelines, and pre-merge checks, decreasing production bugs by 30%, and accelerating release cadence.
• Partnered with UX designers and backend engineers to deliver end-to-end features, improving usability and retention through iterative user testing.
• Drove performance and accessibility improvements to ensure fast, inclusive user experiences.

• Designed and shipped a Google Sheets add-on using Google Apps Script to automate customer workflows and reduce manual tasks.
• Built multiple Nuxt.js and TypeScript applications, emphasizing scalability, maintainability, and clean architecture.
• Rapidly onboarded new tools and libraries to meet project timelines and product requirements.

• Delivered user interfaces and interactive features that supported business operations and customer-facing products.
• Contributed to the successful launch of a payroll automation system, and ensured cross-browser compatibility and performance.
• Actively participated in code reviews to maintain coding standards, and accelerate onboarding for teammates.

• Translated Figma designs into responsive, production-ready React interfaces using JSX and Tailwind CSS, focusing on pixel accuracy and performance.
• Integrated REST APIs to power dynamic user experiences, and managed source control workflows with Git/GitHub.
• Collaborated within a multi-disciplinary team to ship features on tight timelines.
