Welcome! I am

Develop. Scale. Simplify.
A Software Engineer dedicated to creating impactful web experiences. I specialize in designing and developing outstanding digital solutions. Right now, I build scalable payment platforms and AI-powered systems at Weiblocks.
About Me
I design, develop, and simplify to deliver scalable platforms built for growth, from high-traffic applications that stay resilient under peak demand to multi-market payment and revenue systems powering fintech and consumer platforms. With a product-first mindset, I focus on solutions that unlock real business impact.
At WeiBlocks, I architected a payment escrow platform across 11 NestJS microservices with Kafka event streaming and a double-entry ledger for full financial auditability. I also built a market data aggregation engine and a marketplace handling 12K+ concurrent user sessions. Before that, at KadiPay, I built and scaled a BNPL fintech platform serving 50K+ active users, with a React Native mobile app and React web portals on a microservices backend.
I’ve developed projects like Escrowly, Coinperps, Kadipay, and other production-grade platforms.
I’m also experienced in AI-integrated applications using LangChain, RAG pipelines, LLM orchestration, and intelligent automation workflows. My stack runs deep across Node.js, TypeScript, NestJS, React, Next.js, PostgreSQL, MongoDB, AWS, Docker, and Kubernetes, but I pick what fits the problem, not the other way around.
Open to remote opportunities.

Where I’ve Worked
Software Engineer @ Weiblocks
July 2024 - Present
- Led 4 engineers to architect and deliver a production payment escrow platform from concept to deployment, featuring 11 NestJS microservices, Kafka with Transactional Outbox ensuring zero-loss payment events, a double-entry ledger for audit compliance, PostgreSQL with schema-per-service isolation, and AWS KMS wallet encryption. Live ↗
- Engineered a real-time cryptocurrency data aggregation platform unifying market data across 20+ exchanges and 6 news sources, processing 5M+ data points daily through a WebSocket/REST hybrid architecture with intelligent reconnection and failover mechanisms to ensure high availability and fault-tolerant delivery. Live ↗
- Architected and delivered a full-stack marketplace using Node.js, Next.js, and RLS-secured PostgreSQL, enabling creators and resellers to trade digital products. Scaled to 12K concurrent sessions, maintained sub-300 ms API latency, and ensured payment event reliability through Stripe Connect.
Some Things I’ve Built
Featured Project
Escrowly
A production-grade escrow platform built on a microservices architecture, designed to handle complex financial transactions reliably at scale. I engineered the core payment infrastructure including a transactional outbox pattern that guarantees zero-loss event delivery to Kafka, even under service failures or network instability. On the consumer side, idempotent processing ensures transactions are never double-counted, no matter how many times an event is retried.
- Node.js
- Microservices
- Kafka
- PostgreSQL
- Docker
- Event-Driven

Featured Project
Coinperps
A real-time analytics platform that consolidates market data across exchanges into a single, fast API. I built the entire data pipeline: funding rates, liquidations, open interest, ETF, and a live news engine that scrapes major outlets and monitors high-signal Twitter accounts in parallel. The engineering challenge was a tiered caching system that serves millisecond-fresh data where it matters and conserves resources everywhere else.
- Node.js
- Express
- MongoDB
- Redis
- WebSockets
- Puppeteer
- Node-Cron

Featured Project
Flyverr
A digital marketplace MVP built and shipped in 4 weeks — designed for creators and resellers of limited digital products. I architected the full backend with database-level Row-Level Security, Stripe payment integration, and async job queues that kept every flow under 300ms even under heavy load. Scaled to 12,000 concurrent sessions in stress tests without breaking a sweat.
- Node.js
- Next.js
- PostgreSQL
- Supabase
- Stripe
- Row-Level Security

Other Noteworthy Projects
Web3 NFT Listing Website
Built a scalable Web3 NFT listing website with a Node.js backend and React front-end. Implemented pagination, lazy loading, and optimized database queries to efficiently handle large volumes of NFTs. Improved backend performance by leveraging caching and asynchronous data fetching for faster, more reliable responses.
Kadipay Fintech Application
Developed a microservices-based Fintech (Buy Now Pay Later) application at scale, featuring a mobile app built with React-Native and four equally important web portals serving over 50k active users. Enhanced a Java backend designed for microservices architecture, supporting seamless code shifts to production through a well-defined CI/CD pipeline. Refreshed the frontend service layer by linking APIs with robust state management solutions, resulting in approximately 25% improvement in load times. Executed end-to-end testing in various scenarios, ensuring system reliability and achieving a 95% pass rate for all testing filter effects.
Next.js News Blog Application
Developed a highly efficient news blog application using Next.js and React, focusing on superior SEO performance. Utilized server-side rendering and static props to enhance loading times and search engine visibility. Integrated efficient image handling and selected a user-friendly template to improve user experience. Added text-to-speech functionality using browser features and implemented a player for user controls. Organized news content into categories for better navigation and readability.
Holding Hands Community Platform
Created a platform for the Holding Hands Community to support families financially in times of need.
