Senior Software Engineer | Marketplace & Distributed Systems | Matching, Staffing, Experimentation | Kafka, Temporal, Data-Driven Systems
Senior software engineer with ~10 years of experience building and operating marketplace, matching, and decision engines under real-world constraints. I currently work at Zenjob, where I’ve spent several years designing and running mission-critical systems at scale — including matching pipelines, staffing engines, ranking algorithms, and automation workflows that handle millions of events per day. My work sits at the intersection of distributed systems, data-driven experimentation, and product decision-making. I specialise in problems where supply and demand need to be balanced dynamically: fulfilment vs quality, speed vs correctness, automation vs control. I’m comfortable owning systems end to end — from system design and rollout strategy to observability, operations, and iterative optimisation. Technically, I work mostly on backend and data-heavy systems: event-driven architectures, Kafka, transactional workflows, PostgreSQL performance tuning, and data pipelines that make system behaviour observable and explainable. I care deeply about incremental delivery, reversibility, and using data to guide decisions rather than opinions. Earlier in my career, I worked on large-scale serverless systems at StudyPortals and led my first zero-downtime migrations while still at university — which set the foundation for how I approach system design today. I’ve spent most of my career working on marketplace systems, where real-world constraints, bursty traffic, and human behaviour directly shape system design.

Cultural Fit Analysis
The candidate has worked in diverse companies (Zenjob, FlixBus, Studyportals) and on varied projects, from marketplace mechanics to data engineering and serverless platforms. However, the target role is 'Frontend Developer,' while the candidate's experience is almost exclusively backend and data engineering. This significant mismatch in core domain expertise suggests a potential cultural fit challenge for a dedicated frontend role, unless there's an unstated desire to transition or a broader full-stack expectation.
Soft Skills & Operational Fit
The candidate's experience descriptions highlight leadership, collaboration with product and data teams, and mentoring, indicating strong soft skills relevant for senior roles. Their work on complex, high-throughput systems suggests a robust operational fit for demanding technical environments.
