Satwika Hotwani

Software Engineer with 3+ years designing, building, and scaling production-grade Java backend systems — including a Kafka-based pipeline processing 500K+ transactions/day and mission-critical microservices at Bank of America. Strong foundation in data structures, algorithms, and system design (HLD/LLD), with hands-on experience making distributed-systems trade-offs (idempotency, fault tolerance, high availability) at scale. Follows rigorous engineering practices — JUnit/Mockito testing, peer code reviews, CI/CD — and has integrated AI-assisted development tools (GitHub Copilot) into real engineering workflows, including code generation and legacy-code migration.

Comfortable working across the stack, with self-directed exposure to React and component-based UI development, and a track record of mentoring junior engineers.

Software Engineer 1A at Bank of America (2024-09 – Present)

Stack: Java, Spring Boot, Kafka, IBM MQ, REST APIs, SQL, Jenkins, AWS, Linux

• Designed and operated a Kafka-based event-driven pipeline for high-value payment clearing, processing 500K+ transactions/day with real-time monitoring — engineering trade-offs around throughput, consistency, and fault tolerance at scale.
• Built and maintained high-availability backend microservices for mission-critical payment clearing, owning system reliability, scalability, and observability end-to-end.
• Implemented AES-based encryption for secure transmission of 1,000+ daily payment transactions, meeting enterprise security and authentication standards.
• Led peer code reviews across 5+ backend services, establishing coding standards and CI/CD quality gates that reduced post-release defects and raised overall code quality.
• Mentored 3 junior engineers on Java/Spring Boot best practices and collaborative engineering workflows, cutting onboarding time by 30%.

Software Engineer 1B at Bank of America (2022-07 – 2024-08)

Stack: Core Java, Spring Boot, MuleSoft (Anypoint), RESTful APIs, Oracle SQL, IBM MQ, JUnit, Mockito, SonarQube, Git, Maven, Jenkins, CI/CD

• Developed and enhanced 10+ RESTful APIs on the MuleSoft Anypoint platform, and owned a full platform migration (Mule 3.9 → 4.0) end-to-end with zero downtime — including design, testing, and rollout.
• Designed an idempotent Retry API using unique transaction IDs to safely reprocess failed payments — a system-design decision applying distributed-systems fundamentals (idempotency, fault tolerance) to eliminate duplicate-charge risk.
• Improved system stability by refactoring message-handling logic and tuning database interactions, reducing recurring production incidents by 20%.
• Built and optimized Java Spring Boot RESTful APIs and backend business logic (Core Java, OOP, data structures & algorithms) for payment-processing workflows, improving transactional throughput.
• Maintained 90%+ SonarQube coverage via JUnit/Mockito test suites in automated CI/CD gates — embedding testing and code-quality discipline into the full release cycle.
• Partnered with stakeholders and architects across a multi-team platform environment to translate business requirements into secure, scalable technical designs (HLD/LLD).
