Acobe — Software Architecture Studio · Gothenburg, SE
Senior fullstack engineering and software architecture for high-stakes products — payments, enterprise platforms and real-time systems. Built to survive production, not just the demo.
01 / Mission
I'm Alexander Sopov — a senior fullstack engineer and software architect with a decade of shipping production systems for companies that can't afford to get it wrong: Schibsted, Emerson, Dun & Bradstreet and Qamcom, plus my own payments platform. Chalmers-trained, equally at home in the backend (Node, Java, Kafka, AWS) and a polished React or Vue front end.
Acobe is a one-person studio by design. You work directly with the architect writing the code — no handoffs, no account managers, no telephone game. I embed with your team or run the build end-to-end, from system design to the last pixel.
02 / Services
Scalable React, Vue and Next.js applications, design systems and component libraries — engineered for teams of one to one hundred.
Swish, Autogiro and card flows, Stripe integrations and event-driven money movement. I've built a donation platform end-to-end — I know where payments break.
APIs, microservices and event-driven backends in Node and Java/Spring — Kafka, AWS and Kubernetes, built to scale and stay observable.
System design, codebase audits, TDD discipline and team mentoring. I've led teams and trained 100+ developers to industry standard.
Data-dense, real-time UIs for industrial and operational tools — and increasingly, motion and WebGL for products that need to feel as good as they work.

04 / Process
Goals, constraints, users and success metrics. We define the mission — and the risks — before touching the launchpad.
System architecture, data contracts and technical proofs. The parts that can sink the project get de-risked first.
Short cycles, weekly demos, tested production code from day one. You see working software, not promises.
Ship, measure, iterate. Handover with docs and tests — or stay in mission control with your team.
