About Karan Pahlani
Senior Software Engineer and Team Lead with a passion for transforming complex technical challenges into measurable business value. I specialize in architecting and building scalable, high-impact backend systems, with deep experience in evolving legacy monoliths into modern, distributed architectures.My core focus is on delivering results. I drove the multi-year strategic migration of a monolithic Java/MongoDB application to a robust ecosystem of Go microservices, using a polyglot persistence strategy with PostgreSQL, DynamoDB, and Redis to optimize for performance and cost. This wasn\'t just a technical exercise; it was about enabling the business to move faster, scale reliably, and unlock new opportunities for growth.Some of my proudest accomplishments include: Extreme Scalability: Engineered systems to handle over RPS (a 10x increase) during Super Bowl ad campaigns, ensuring flawless performance under massive load. Cost Optimization: Architected a data aggregation service that cut monthly cloud costs by over $30K while simultaneously improving data accuracy for partners. Developer Velocity: Built a self-service authentication platform that empowered 25+ partners to onboard independently, reducing engineering integration time by 90%. Product Impact: Led the development of a universal product catalog that became the central source of truth for product data, boosting offer matching accuracy by 35%.I believe the best software comes from a deep understanding of the business problem and a collaborative, team-oriented approach. I am always looking for opportunities to mentor teammates, improve engineering processes, and build products that have a real and lasting impact.Specialties:Backend Development | Distributed Systems | Microservices Architecture | Cloud Architecture (AWS)Monolith to Microservices MigrationHigh-Availability & Scalable SystemsLanguages: Go (Golang), Java, PythonDatabases: PostgreSQL, DynamoDB, Redis, Snowflake, MongoDBInfrastructure & DevOps: Kubernetes (k8s), Docker, Kafka, Terraform, CI/CD (BitBucket Pipelines)Observability & Monitoring: OpenTelemetry, Grafana, PagerDuty, Hosted Graphite
