Summary
👤
Senior🎓
Top SchoolMatas Šeimys is a Senior Software Engineer with 12 years of hands-on experience building full-stack, data-driven web platforms and AI-enabled automation tools from Vilnius, Lithuania. He blends a physicist’s analytical rigor with practical product sense—co-founding Polltix and leading engineering at Genus AI to automate creative production and optimize ad campaigns using TypeScript/React frontends and Python/Django backends integrated with OpenAI and Kafka. Comfortable across frontend, backend and DevOps, he has scaled services on AWS (CloudFormation, ECS), implemented GraphQL, Celery workflows and real-time pipelines, and worked on medical imaging and ML‑adjacent stacks earlier in his career. Known as a clean coder who won’t accept “it works” as good enough, he enjoys tackling “unsolvable” problems and improving processes from CI/CD to data pipelines. His background in theoretical and biophysics informs a measured, model-driven approach to engineering trade-offs and optimization.
