I’m a Senior Full-Stack Engineer and Founding Engineer with over 8 years of experience building SaaS products and web applications from scratch. My core expertise lies in end-to-end product development — frontend, backend, architecture — combined with a strong business and product mindset.

While I primarily specialize in SaaS development, I also have a deep passion for web3, crypto and blockchain, which has driven me to build numerous experimental and production-ready tools in that space. Alongside my personal projects, I have also contributed to freelance projects, both in web3 and outside of web3, helping startups and companies deliver reliable, scalable solutions.

Some of the projects I’ve built include:

• Stellar (in progress) — a SaaS AI-driven HR recruitment platform that matches candidates with job descriptions.

• Multiple crypto trading bots using different strategies (RSI, price spikes, pump-and-dump detection, volume simulation).

• Neumorphism — a React component library for modern UI design (https://react-neumorphism.benao.io/).

• A Pinterest affiliate automation bot generating 300k+ monthly views (https://pin.it/194ds8vT2).

• Sunland — an Ethereum NFT collection built from scratch with Solidity smart contracts and a minting application (https://sunland.benao.io/).

I excel at transforming ideas into complete products, blending engineering, product thinking and business awareness. Whether for SaaS platforms or innovative web3 initiatives, I bring the versatility of a senior full-stack engineer ready to build from zero to launch.

As a Senior Founding Engineer at Suby, a Web3-focused startup, I contributed to building the core platform and payment infrastructure designed for private Web3 communities. I worked closely with the founders to shape the product architecture, define technical standards, and deliver scalable features from the ground up.

My work spanned the full stack, using React, TypeScript, Next.js, NestJS, and Node.js, with a strong focus on reliability, security, and a seamless user experience. I helped Suby lay the technical foundation for a new kind of payment system tailored to decentralized and gated online communities.

As a Senior Fullstack Engineer at Dialog, I contributed to developing a SaaS platform leveraging AI to help e-commerce businesses boost sales. I worked on building and scaling features that enhance user experience and streamline sales processes, collaborating closely with the product and data teams.

My work covered the full stack, using Node.js, TypeScript, NestJS, React, PostgreSQL, and AWS, focusing on performance, reliability, and delivering AI-powered solutions that drive measurable business impact.
