My Services

01
Technology Leadership
When companies need senior technical direction but not a permanent CTO, I provide leadership as interim CTO, align technology with business goals, mentor teams, and set a clear path forward.
02
Scalable System Architecture
I design modular, future-proof systems including microservices, APIs, event-driven workflows, and offline-first patterns. The goal is always performance today with maintainability tomorrow.
03
Hands-on Software Development
I stay hands-on because good architecture is proven in code. I focus on clarity and maintainability while guiding teams to deliver software they can trust and evolve without friction.
04
Cloud and DevOps Foundations
I design infrastructures that scale smoothly, stay resilient under pressure, and recover quickly from failure. Automation and monitoring keep systems predictable while controlling complexity and cost.
05
Product-Driven Technical Guidance
I bridge business goals with engineering reality, shaping roadmaps and priorities through a builder’s perspective. This ensures product decisions are grounded in what can scale, evolve, and deliver real value.
06
Emerging Technologies in AI and Web3
I guide teams in applying new technologies where they create real value, from embedding AI into workflows to turning blockchain concepts into usable products.

About Me

I’m a Software Architect with more than ten years of experience turning complex challenges into scalable solutions. My work has spanned media, publishing, e-commerce, real-time streaming, and geospatial technology, each demanding reliability, performance, and adaptability.

I focus on modern frontend platforms and cloud-native backends that are fast to build, resilient in production, and sustainable over time. React, React Native, GraphQL, AWS, and event-driven systems are tools I use often, but the real value lies in choosing the right patterns and trade-offs to serve business goals.

Over the years I have rebuilt mission-critical systems, guided architectural migrations, and introduced DevOps practices that helped teams deliver faster with greater confidence. I have worked with startups racing to launch and with enterprises scaling globally, always aiming to create environments where developers can thrive.

What I enjoy most is connecting business vision with technical execution. I am known for pragmatic leadership, clear communication, and mentoring engineers to think in systems rather than in isolated pieces of code. For me, great architecture is not only about technology but also about enabling teams and products to grow without friction.

I re-architected a customer-facing sales web application for a manufacturer-focused company, ensuring scalability and a modern user experience. On the frontend, I led development with React and Next.js, supported by a custom UI library built on MUI. On the backend, I developed the platform with Nest.js and MongoDB and deployed it on a serverless AWS architecture for robustness and cost efficiency. I also led the overall architecture and AWS infrastructure design, implementing infrastructure-as-code, DevOps practices, and GitOps deployments to deliver a fully automated and reliable delivery pipeline.
