Full Stack Product Engineer turning complex product operations into secure scalable solutions with Node.js (Express.js, Nest.js), Ruby On Rails, and React.js

Full-stack software engineer with 13+ years of production experience, specialising in Ruby on Rails backends and React frontends - with growing Node.js/NestJS depth in TypeScript-native projects.
Individual contributor, owning product feature delivery end-to-end - driving architecture decisions, mentoring juniors.

I help companies turn business requirements into production-ready software: from MVPs that need to launch fast to enterprise systems that need to scale, stay secure, and keep shipping under pressure.

Across 30+ delivered projects, I’ve built and extended platforms used by millions of users, contributed to SOX-compliant systems, shipped real-time and high-load applications, and led delivery across complex
product environments. My work has supported measurable business outcomes, including 7% conversion growth, faster go-to-market, lower maintenance overhead, and reliable scaling in production.

I work across the full stack, with a strong focus on architecture, execution, and business alignment. That includes React, Next.js, Node.js, Ruby on Rails, NestJS, AWS, distributed systems, payments, integrations, and cloud infrastructure.

What clients get from working with me:
- Clear technical decisions, not endless options
- Strong ownership and high agency
- Clean, maintainable code with production standards from day one
- Fast adaptation to new tools, changing scope, and delivery pressure
- A bias for experimentation, iteration, and measurable results

What I deliver:
- Product and system consulting
- Custom web application development
- SaaS platforms and multi-tenant systems
- API design and third-party integrations
- E-commerce platforms and payment flows
- Performance optimization and scaling
- AWS infrastructure and architecture
- UX/UI improvements that support engagement and conversion

I’ve worked with companies such as Svitla, Seeking Alpha, Apriorit, Yalantis, LoopMe, and The Skills, building systems where reliability, speed, and business impact all matter.
If you’re looking for someone who understands both the technical side and the business side, and can turn complexity into working software, let’s talk.

Work Terms

A senior or lead-level full-stack role on a product that solves a real problem for real users - ideally with a Rails or Node.js/NestJS/Next.js backend and a React frontend. I'm most effective on teams that value clean architecture, test coverage, and thoughtful code review - not just shipping features fast and fixing them later.
I want meaningful technical ownership: contributing to architecture decisions, not just implementing tickets. A team where senior engineers have a voice in how things are built, not just what gets built next sprint.
Domains that genuinely interest me: fintech, developer tooling, data-intensive platforms, IoT/real-time systems, and anything with non-trivial complexity - subscriptions, multi-tenancy, event-driven pipelines, high-throughput APIs.
I'm also drawn to teams that are actively integrating AI tools into their engineering workflow - not as a buzzword, but as a practical multiplier on delivery quality and speed.

Remote is preferred. Async-friendly culture matters more to me than a specific timezone overlap.
