👤
Senior🎓
Top SchoolGrzegorz Kawka is a Senior PHP Developer with 11 years of experience designing and delivering web applications and mobile integrations from Warsaw, Poland. He has progressed from junior roles to senior/architect and team lead positions, shaping architecture, mentoring teams, and driving agile practices at companies including Shoplo (acquired by SumUp) and GoldenLine.pl. His strengths include backend optimization, stability engineering, and end-to-end feature delivery, with hands-on experience in testing strategy and technical documentation. Grzegorz often bridges development and operational concerns—covering server administration, R&D and performance tuning—so solutions are both robust and maintainable. He pairs an engineer’s rigor (MSc in IT Project Management and an engineering degree in Software Engineering) with practical leadership that elevates team capabilities. Less obvious: he has repeatedly shifted between individual contributor and people-leader roles, signaling both deep technical craft and a talent for mentoring.
