About Me

I’m a SaaS architect, full-stack developer, and AI product engineer with over 15 years of experience building SaaS products, marketplaces, and data-heavy applications end to end. I work with startups and product teams to ship reliable systems that scale, perform well, and are easy to maintain.

What I Work On

My work spans the full stack: designing clean backends with Node.js, NestJS, and GraphQL, building fast user-focused interfaces with React and Next.js, and deploying production systems on AWS using infrastructure as code and CI/CD pipelines.

I’ve delivered web, mobile, desktop, and cloud-native products across fintech, AI, SaaS, Web3, and automation, often owning systems end to end and working directly with founders where clarity and accountability matter.

Experience & Impact

Over the years, I’ve helped teams improve performance, reduce cloud costs, and stabilize production releases. This includes rebuilding applications to cut load times dramatically, designing scalable services, integrating AI APIs, and shipping features used by real users in production.

I’m comfortable working across the entire lifecycle, from early MVPs to mature products, and I focus on technical decisions that balance speed today with flexibility tomorrow.

How I Approach Engineering

I prefer simple, well-structured solutions backed by clear architecture. Before writing code, I spend time understanding the problem, constraints, and trade-offs so the system fits both technical and business goals.

My day-to-day approach includes performance profiling, secure coding practices, and pragmatic testing where it adds real value. I aim to leave teams with systems they can confidently evolve, not brittle codebases.
