ZeroNorth
Senior Software Architect / Technical Lead
- Modernised legacy monolithic systems to an event-driven microservices architecture (EDA), resulting in a 30% increase in deployment frequency and reduced technical debt.
- Led engineering implementation of ML/AI voyage optimisation models, contributing to a 15% reduction in fuel consumption and driving environmental sustainability.
- Built the Fleet Telemetry service that ingests vessel events and pre-computes metrics, cutting platform load time from ~8s to under 1s.
- Designed and built the notification delivery system from scratch — Go microservices on AWS (SNS/SQS) powering web and email notifications across the product.
Qlik
Senior Software Engineer
- Established technical standards for Golang microservices, enhancing code quality and maintainability across the engineering organisation.
- Mentored junior developers; implemented best practices that reduced defect injection by 80% during QA cycles.
- Diagnosed and resolved critical performance bottlenecks, yielding a 10% improvement in API response times.
- Led migration of the platform's core event distribution infrastructure to a new message broker — zero downtime, no disruption to downstream services.
Boozt
Engineering Manager
- Scaled the warehouse logistics engineering org to one team in Lithuania and three teams in Sweden (3 → 17 engineers, 96% retention over 7 years).
- Led the full removal of the Element Logic system, replaced by a direct integration to the AutoStore Bin Task System — delivered in 3–4 months with major gains in picking and packing speed.
- Integrated an automated shelf storage system (for perfumes and similar goods) and Toyota robotic forklifts into the Boozt WMS.
- Architected a zero-downtime migration strategy for warehouse software relocation — 0% impact on fulfilment operations.
Boozt
Team Lead
- Led a team of developers in Sweden building core e-commerce and logistics platform features.
- Replaced the slow, unreliable Boxon FTP integration with a direct conveyor integration over OPC-UA — rewritten from C to Go — unlocking weight-based sorting and dynamic distributor-to-exit slide assignment.
- Worked closely with the AutoStore R&D team on robot upgrades and platform-side changes to keep pace.
Boozt
Senior Software Engineer
- Joined as the second engineer in the logistics department, building the core WMS from the ground up.
- Built the AutoStore integration (Element Logic, file-based) into Boozt's WMS, powering the move from a fully manual warehouse to a new robotic one with zero items out-of-stock during the transition.
- Wrote a custom low-level label printing service in ZPL for Zebra printers, significantly accelerating the packing flow.
- Designed and refined picking strategy across the WMS, driving higher warehouse throughput and lower error rates.
Ivy Exec
Senior Software Engineer
- Acted as the team's Solr search expert on a specialised job ads service built for the US market.
- Re-engineered Solr search infrastructure, improving candidate matching relevance for 10,000+ hiring managers.
- Optimised platform for high-concurrency US market traffic, ensuring stability during peak recruitment seasons.
Infostud
Software Engineer
- Owned analytics for the job serving service, turning user behaviour data across 1M+ users into feature decisions — lifting engagement metrics by 5%.
- Contributed to a ground-up rewrite of the job serving service in PHP and MySQL, migrating off the legacy codebase onto a cleaner foundation.
