Software Engineer III
Foundry Digital
- Developed and deployed microservices in Kotlin and Spring Boot, integrating AWS Secrets Manager to secure credentials and decreasing network calls using Spring cache.
- Refactored Kafka consumer using Spring Kafka with Semaphore-based backpressure to cap records and keep heap memory stable under spikes. Switched to batch upserts to cut down on DB invocations. Added Testcontainers integration tests for Kafka & DB to pave the way for future changes.
- Automated the financial reconciliation workflow in Spring Boot (Kotlin) using Spring Scheduler (cron jobs), Transactional boundaries, JPA/Hibernate on MySQL, and Flyway migrations saving the Accounts team 16+ hours/week.
- Designed and Dockerized payments E2E test framework in Robot (Python) with reusable keyword libraries and profiles. Integrated with GitLab CI (Jacoco XML + HTML reports) to accelerate releases and lift code coverage to 80%.
- Implemented end-to-end observability on Datadog by instrumenting services with Datadog APM, correlated metrics/logs and provisioned dashboards, created monitors with burn-rate alerts and anomalies, hardening reliability and giving stakeholders clear visibility.

Senior Software Engineer
SHS Viveon AG
- Implemented single sign-on using Keycloak, OIDC with ID Tokens: configured realm settings (redirect URIs, scopes, exp/iat), claim mappers, and Spring JWT validation. Enforced server-side token exchange (back-channel) to eliminate front-channel token leakage.
- Identified critical CVEs using Snyk and remediated by upgrading vulnerable dependencies via Gradle, replaced risky transitive dependencies and added CI steps and security gates to automate vulnerability detection.
- Optimised DB interactions across the hibernate layer eliminating N+1 queries, adding composite indexes, tuned to batch writes reducing latency and network calls.
- Orchestrated MR-triggered pipelines with GitLab CI: semantic-versioned Docker images, Helm charts, Readiness probes, auto-rollback on failed probes eliminating the need for manual monitoring during deployments.

Senior Engineer (Payments)
Deutsche Bank
- Designed type-safe Kotlin DSLs to model payment orchestration and compliance rules; compiled DSL into executable Spring components eliminating scattered boilerplate code, increasing maintainability and robustness.
- Developed regulatory payment flows across Spring Boot/Kotlin microservices implementing idempotency keys, safe retry logic, and audit logging increasing system transparency and reducing error scenarios.
- Improved data consistency and reporting by performing root-cause-analysis for redundant datasets and fixed SQL queries with Clickhouse DB.
- Collaborated with geographically distributed teams and Business analysts to understand real-time challenges and discussed different implementation tradeoffs to reduce multiple iterations on existing issues.

Modifi
- Designed and developed an Invoice Management microservice in Java / Spring Boot with PostgreSQL, JPA/Hibernate. Improved transaction reliability using idempotency keys, keeping clear Transactional boundaries making it highly fault tolerant.
- Refactored the shipment tracking service with modularised design and clear logs to make failures transparent. Reduced downtime and enhanced stability by introducing retry logic for external API calls with Seagate.
- Improved developer workflow and deployment speed through GitLab CI/CD pipeline optimization and built Grafana dashboards to increase operational visibility for stakeholders.
- Raised code quality and delivery standards by documenting best practices with other team members.

Infogain / Solunus
- Revamped airline seat management microservices enabling partner bookings and scaling availability.
- Upgraded existing microservices to Java 11 and revisited container images (to Alpine) for right-sizing, lowering infra costs and minimising security threats.
- Developed a custom logging and tracing framework using Logback, reducing incident resolution time by 30%.
- Built pipelines and automated CI gates with Jenkins enhancing automation.
Dec 2019 - Aug 2020
