I help startups and SaaS companies build software that continues to scale as the product grows. I enjoy joining projects at the point where things stop being simple. Maybe your product has grown faster than expected. New features are getting harder to ship, technical debt is slowing the team down, or the architecture that worked for the first version is starting to show its limits. That's usually where I can help. For the past 12+ years, I've been helping teams turn ideas into production software - and, just as importantly, keep that software maintainable as the business evolves. I work across the entire stack, from modern frontend applications to backend architecture and infrastructure. But clients don't hire me because I know React, Laravel, Vue, or any other framework. They hire me because I can quickly understand a complex system, make sound technical decisions, and build solutions that other engineers can confidently extend months or years later. Over the last few years, AI has naturally become part of my work. I've integrated LLMs into existing SaaS platforms, built AI-powered features and internal tools, automated workflows, and used AI to speed up development without sacrificing engineering quality. I don't build AI for the sake of it - I use it when it solves a real problem and delivers measurable value. One thing clients often tell me is that they don't have to manage me. I communicate clearly, ask the right questions early, and take ownership of the work. If I see a simpler solution, I'll suggest it. If I think a decision is likely to become technical debt six months from now, I'll raise that concern before we write the code. Beyond web development, I also work with Rust and systems programming, including Solana smart contracts, SDK development, asynchronous programming with Tokio, concurrency, and performance-critical software. That experience has shaped the way I think about performance, reliability, and software architecture across every project I work on. Whether you're building a new SaaS product, scaling an existing platform, modernizing a legacy application, or adding AI capabilities to your product, I'd be happy to help.

Hi, I'm George, a full stack software engineer with 4+ years of professional experience based in the San Francisco Bay Area. Things I recently worked on: - Frontend web development at Virufy, a medtech AI non-profit. I developed the marketing web app from the ground up to support internationalization and deployment to Github Pages using Next.js. I also transformed Figma designs into responsive web pages using React, Typescript, and Tailwind CSS. I was formerly at: - Tigo Energy, a mid-size renewable energy company, modernizing the tech stack for their flagship software product, Energy Intelligence (EI), designing and implementing new classes and schemas for their auditing tool using PHP and SQL, and writing PHP scripts to migrate data from Postgres to Clickhouse, which has shown to improve query performance by up to 10x. - Northwestern Mutual, a massive financial services company, building internal web search tools with NestJS, React, Typescript, and Apollo GraphQL to fetch insurance policy data in real-time from various data sources (ie. AWS RDS, IBM Db2), and a PII data masking application in Golang. Although most of my experience has been backend and full-stack, frontend web development is becoming my newfound passion. I find collaborating with UI/UX designers and building professional and engaging user interfaces and experiences to be fun and rewarding.
