I build backend systems that scale — and teams that deliver them. Over 10 years, I've architected high-performance infrastructure for SaaS platforms, AdTech networks, and e-commerce marketplaces across India, Sweden, and the US. I specialize in solving the hard problems: high-concurrency databases, distributed caching, legacy-to-cloud migrations, and the cross-timezone team dynamics that make or break a delivery. What I've shipped: → 30–50% backend performance gains via Redis caching and MySQL query tuning → Multi-vendor marketplace built on top of a single-seller SaaS core — complex data isolation and transaction routing at scale → Kubernetes-led containerization of legacy monoliths at Admedia, targeting 99.9% uptime → Real-time Elasticsearch with auto-suggest across millions of records → Payment & logistics integrations: Stripe, Klarna, Nets Easy, PostNord, nShift Currently at Admedia, architecting backend services for AdCenter, Stockprices.com, and Items.com — managing real-time ad delivery pipelines with PHP 8+ and MySQL HeatWave. Previously at Textalk Group/Abicart India for 5+ years as Senior Developer and Lead — owning checkout systems, leading a distributed India–Sweden team, and driving DevOps maturity through CI/CD and containerized deployments. I'm actively exploring Staff Engineer, Backend Architect, and Engineering Lead roles at product companies across India and anywhere in the World(Remote). Open to relocation.
