I focus on end-to-end ownership, from architecture and technical design through delivery, production support, and continuous improvement. My background combines applied mathematics with strong analytical thinking, which helps me solve complex engineering problems and make sound technical decisions. I have deep experience with microservices, REST and GraphQL APIs, event-driven systems, cloud infrastructure on AWS, and modern backend practices such as test-driven development, domain-driven design, and clean architecture. I also enjoy working closely with stakeholders, mentoring engineers, leading teams, and turning product ideas into reliable software that delivers business value. I am AWS Certified Solutions Architect and comfortable working across backend engineering, system design, performance tuning, and production operations. ## Skills ### [AWS](https://jobicy.com/talent/aws.md)[Java](https://jobicy.com/talent/java.md)[React](https://jobicy.com/talent/react.md)[Docker](https://jobicy.com/talent/docker.md)[CI CD](https://jobicy.com/talent/ci-cd.md)[Git](https://jobicy.com/talent/git.md)[Team Leadership](https://jobicy.com/talent/team-leadership.md)[Agile](https://jobicy.com/talent/agile.md)[PostgreSQL](https://jobicy.com/talent/postgresql.md)[MySQL](https://jobicy.com/talent/mysql.md)[Mentoring](https://jobicy.com/talent/mentoring.md)[Kafka](https://jobicy.com/talent/kafka.md)[Jenkins](https://jobicy.com/talent/jenkins.md)[Microservices](https://jobicy.com/talent/microservices.md)[MongoDB](https://jobicy.com/talent/mongodb.md)[GraphQL](https://jobicy.com/talent/graphql.md)[Distributed Systems](https://jobicy.com/talent/distributed-systems.md)[Redis](https://jobicy.com/talent/redis.md)[Code Review](https://jobicy.com/talent/code-review.md)[Grafana](https://jobicy.com/talent/grafana.md)[Kotlin](https://jobicy.com/talent/kotlin.md)[Prometheus](https://jobicy.com/talent/prometheus.md)[Airflow](https://jobicy.com/talent/airflow.md)[Serverless](https://jobicy.com/talent/serverless.md)[REST](https://jobicy.com/talent/rest.md)[Elasticsearch](https://jobicy.com/talent/elasticsearch.md)[Spring Boot](https://jobicy.com/talent/spring-boot.md)[Design Patterns](https://jobicy.com/talent/design-patterns.md)[DynamoDB](https://jobicy.com/talent/dynamodb.md)[S3](https://jobicy.com/talent/s3.md)[RabbitMQ](https://jobicy.com/talent/rabbitmq.md)[Lambda](https://jobicy.com/talent/lambda.md)[IAM](https://jobicy.com/talent/iam.md)[Test Driven Development](https://jobicy.com/talent/test-driven-development.md)[Performance Tuning](https://jobicy.com/talent/performance-tuning.md)[gRPC](https://jobicy.com/talent/grpc.md)[New Relic](https://jobicy.com/talent/new-relic.md)[Event Driven Architecture](https://jobicy.com/talent/event-driven-architecture.md)[Kibana](https://jobicy.com/talent/kibana.md)[Gradle](https://jobicy.com/talent/gradle.md)[Maven](https://jobicy.com/talent/maven.md)[Hibernate](https://jobicy.com/talent/hibernate.md)[OWASP](https://jobicy.com/talent/owasp.md)[Kinesis](https://jobicy.com/talent/kinesis.md)[Domain Driven Design](https://jobicy.com/talent/domain-driven-design.md)[OpenAPI](https://jobicy.com/talent/openapi.md)[Swagger](https://jobicy.com/talent/swagger.md)[Database Optimization](https://jobicy.com/talent/database-optimization.md)[JPA](https://jobicy.com/talent/jpa.md)[JBoss](https://jobicy.com/talent/jboss.md)[Spring Data](https://jobicy.com/talent/spring-data.md)[Java EE](https://jobicy.com/talent/java-ee.md)[JSP](https://jobicy.com/talent/jsp.md)[Kafka Streams](https://jobicy.com/talent/kafka-streams.md)[Event Sourcing](https://jobicy.com/talent/event-sourcing.md)[Dropwizard](https://jobicy.com/talent/dropwizard.md)[JProfiler](https://jobicy.com/talent/jprofiler.md)[Claude Code](https://jobicy.com/talent/claude-code.md)[Copilot)](https://jobicy.com/talent/copilot.md) ## Experience Senior Software Engineer @ S0$#WS0 Jul 2025 - Jun 2026 Built a cloud SaaS for wealth planning using ownership graphs and full point-in-time history.
