Ruslan Alekseyev
Senior Technical Partner for Building & Scaling Software Products
I help founders turn ideas into production-ready products — architecture, backend, DevOps, AI integration and hands-on development. Not just advice. Not just code. Architecture + execution.
Not just advice. Not just code.
Most founders do not need just another developer. They need someone who can understand the product, design the architecture, build the core system, set up the delivery foundation and make technical decisions that will not break the product six months later. I work as a senior technical partner who combines architecture and execution — from product idea and MVP to backend systems, DevOps, AI integrations and scalable production delivery.
How I Help Founders & Software Teams
Product Architecture & MVP Build
For founders who need to go from idea to a production-ready MVP — designed and built properly.

Build faster with AI-assisted workflows — guided by senior architecture and code review.
Backend & Microservices Architecture
Design backend systems, service boundaries and APIs that fit the product, team and stage.
Technical Architecture Audit
For founders and CTOs who feel their engineering team is slowing down but do not know exactly why.
AI Production Integration
For teams that already have an AI prototype but need to turn it into a reliable production system.
Fractional CTO / Architecture Partner
Part-time senior technical leadership for teams that need direction without hiring a full-time CTO.
Technical Rescue Sprint

About
I help software teams reduce technical risk.
Over the last 13+ years, I've worked across FinTech, HealthTech, Banking, AI and SaaS systems — leading teams, modernizing legacy platforms, designing backend architecture, building CI/CD pipelines and integrating AI into production products.
My work is focused on one thing: turning technical complexity into systems teams can actually ship, maintain and scale. Based in Barcelona, working with founders and engineering teams worldwide.
