Project History
Infin8 - AI-powered Creator Marketing Platform
https://www.infin8.media/I worked across the platform from architecture through production, including the Next.js frontend, NestJS APIs, PostgreSQL data model, creator matching, campaign workflows, payments, OAuth integrations, background processing, and AI features.
I helped evolve Fin, the platform's AI assistant, from earlier LangGraph/OpenAI-based workflows into a production Claude system on AWS Bedrock. The current architecture uses the model for intent interpretation while deterministic TypeScript controls business rules, state transitions, validation, and execution. This makes the AI layer more reliable for workflows that can affect campaigns, users, and payments.
I also worked on Stripe Connect payouts, escrow and wallet flows, search and matching, social integrations, Redis/BullMQ jobs, real-time features, testing, CI/CD, and production debugging.
Key technologies: Next.js, React, TypeScript, NestJS, PostgreSQL, Prisma, AWS Bedrock, Claude, Redis, BullMQ, Stripe Connect, OAuth2, WebSockets, Docker, AWS ECS, S3, and GitHub Actions.
DuroLabs - Product Lifecycle Management Platform
https://durolabs.co/product-lifecycle-management/I worked across a mature React, TypeScript, Node.js, MongoDB, and GraphQL codebase, improving both product functionality and engineering reliability. I refactored Mongoose schemas and complex BOM workflows, worked on data migrations, and integrated Onshape CAD/PDM so engineering data could move more smoothly between systems.
I also built reusable Material UI components in Storybook and strengthened the automated testing setup using Jest, Cypress, and Puppeteer, helping increase test coverage from around 30% to 80%. Alongside feature work, I handled production issues and made changes carefully in an established codebase where regressions could affect existing customer workflows.
AiTube - AI Video Generation Platform
https://aivideostube.com/I built Prompt Battle, one of the platform's core engagement and monetization features. Brands can create sponsored competitions around a theme, creators submit AI-generated videos, and the community votes on the winning entries.
I designed the credit model so battle participation and AI generation costs map directly to platform usage, helping keep the feature commercially sustainable as AI consumption scales. I also integrated Stripe for package purchases and credit allocation, and built the full battle management workflow from front-end interfaces through back-end logic and database models.
On the admin side, I implemented battle creation, activation, featuring, moderation, prize handling, and supporting controls required to operate the feature in production.
Key technologies: Next.js, TypeScript, Node.js, Python, FastAPI, PostgreSQL, Prisma, Stripe, React Query, REST APIs, OAuth2, AWS, and CloudFront.
Arden - Smart Air Travel Tracking System
https://arden.co/I built the airline integration layer, handling different carrier APIs, authentication methods, and response formats. Each airline returned data differently, so I created carrier-specific mappers to normalize flight, pricing, and upgrade information into a consistent internal model. I also handled carrier-specific access constraints and reliability issues to keep data flowing consistently.
To make pricing and upgrade searches fast enough for real-time use, I implemented an Elasticsearch-based search and used BullMQ for background processing across multiple carriers. The platform continuously monitors airline data and surfaces relevant upgrade opportunities without requiring users to manually check individual airline systems.
Key technologies: TypeScript, Fastify, PostgreSQL, Elasticsearch, BullMQ, Redis, Kafka, OAuth2, AWS, GCP, and Cloudflare.
Linvite Life - Hospitality Mobile Application
https://play.google.com/store/apps/details?id=com.webkype.linvite• Built a dynamic referral system using React Native Skia, leading to better visual experience and higher user satisfaction.
