Senior Backend Engineer | Java, Spring Boot, Snowflake, Azure, Kubernetes, Kafka | Healthcare Platforms

About

I am a Senior Member of Technical Staff at athenahealth with 6+ years building production systems using Java, Spring Boot, SQL, Kubernetes, Snowflake, Azure Cosmos DB, Azure, and REST APIs. Strong in event-driven systems, cloud data pipelines, distributed systems, performance optimization, production debugging, security remediation, and AI developer tooling. My strongest work is at the intersection of Java/Spring backend engineering, SQL-heavy data systems, cloud platforms, and production debugging. I have built and maintained services and pipelines using Java 8/17, Spring Boot, SQL Server, Snowflake, Azure Cosmos DB, Azure storage, Docker, Kubernetes, Jenkins, and Azure Pipelines. Recent work includes optimizing large Snowflake processing workflows, reducing a major processing job from roughly 14 hours to roughly 30 minutes; building SQL Server to Snowflake to Cosmos DB data movement; improving high-volume sync workflows with streaming reads and keyset pagination; adding memory guardrails and Kubernetes resource tuning; and improving observability through metrics and record-level error logging. I also have deep healthcare domain experience across clinical quality reporting, FHIR, CCDA, QRDA, QDM, CQL, MIPS, MVP, PI, IA, and quality measure workflows. I have worked on regulatory reporting updates, QRDA compliance, quality scoring, dashboard workflows, and clinical-data debugging automation. Outside day-to-day product work, I focus on mature developer tooling and engineering-system projects. Public work includes a Zed workspace snapshot CLI for repeatable local workflows, a TypeScript VS Code extension for navigating code comments during review and cleanup, a Java logging library focused on reusable API design, and Rust rendering-engine experiments that show systems-level learning beyond backend application work.

Work experience

Senior Member of Technical Staff at athenahealth, Aug 2023 - Present · 3 yrs 1 mo, Bengaluru, Karnataka, India, • Led production microservices and data workflows using Java 17, Spring Boot, Kafka, SQL Server/T-SQL, Snowflake, Azure Cosmos DB, Docker, Kubernetes, Helm, Jenkins, and Azure Pipelines. • Led adoption of an AI-assisted SDLC using spec-driven development, OpenAI Codex, Claude Code, project knowledge bases, agent- compatible codebases, and code-specific skills. • Created LLM-Wiki-style project knowledge bases and GPT bots using context engineering; implemented guardrails, human-in-the-loop workflows, and MCP integrations. • Built an automated AI code-review tool supporting review guardrails and human-in-the-loop engineering workflows. • Designed and supported event-driven Java microservices using Kafka, REST APIs, Kubernetes, Azure services, and CI/CD pipelines, with integrations across AWS services and Prometheus-based monitoring. • Built and maintained cross-platform data pipelines from SQL Server to Snowflake to Azure Cosmos DB using Azure Blob/Table Storage. • Added streaming mode to a large Snowflake processing workflow, reducing runtime from ~14 hours to ~30 minutes. • Refactored high-volume synchronization logic using streaming reads, shard-by-shard keyset pagination, memory guardrails, JVM heap settings, and Kubernetes resource tuning. • Added dynamic SQL Server shard routing, profile-driven query loading, pre-checks, Prometheus metrics, and improved record-level error logging for Kubernetes workloads. • Partnered with product managers, mentored junior developers, and reviewed code for maintainability and production readiness. • Investigated production issues across application code, SQL queries, cloud resources, generated artifacts, and downstream consumers; improved data correctness and regression confidence with focused proof cases, JUnit, and Mockito. • Supported cloud-backed workflows across Azure and AWS service integrations, including S3, Lambda, and EKS.

Member Of Technical Staff at athenahealth, Nov 2021 - Aug 2023 · 1 yr 10 mos, Bengaluru, Karnataka, India, • Designed and developed Java 8/Spring Boot REST APIs and service integration workflows across APIs, shared libraries, SQL/T-SQL scripts, Maven builds, and release branches. • Refactored frontend and backend code, remediated Checkmarx findings, reduced cross-site scripting risk by 90%, upgraded vulnerable dependencies, and improved maintainability across legacy Java and JavaScript code paths. • Maintained shared libraries, service dependencies, version updates, and cross-service compatibility across a large healthcare platform ecosystem. • Developed JavaScript and jQuery components for data-heavy production workflows and supported Jest/integration testing across service boundaries.

Associate Member Of Technical Staff at athenahealth, Mar 2020 - Nov 2021 · 1 yr 9 mos, Bengaluru, Karnataka, India, • Developed and maintained JavaScript, Play Framework, Java 8, Spring Boot, and REST API web applications. • Improved system performance and availability by 50%+ through optimization and reliability-focused changes. • Worked across requirement gathering, implementation, testing, bug fixing, and Agile delivery with product and engineering stakeholders.
