Available to hire
I am a senior backend engineer with 13+ years designing high-performance systems using Python, Django, Airflow, Next.js, MongoDB, and cloud-native AWS architectures. I specialize in building scalable microservices, optimized data pipelines, and resilient APIs with a strong foundation in distributed systems, DevOps automation, and performance tuning.
I focus on delivering product-ready backends that scale while reducing costs and improving reliability. I thrive in cross-functional teams, emphasize clean API design, and continuously improve observability and security to meet enterprise requirements.

Senior Software Engineer (Python) at Walmart Global Tech
September 1, 2025 - September 1, 2025Re-architected a legacy healthcare platform into distributed microservices (Python/Go), enabling incremental domain deliveries under HIPAA constraints. Designed and scaled patient-facing APIs serving ~3M daily users with 99.99% uptime; owned SLAs and incident response metrics. Introduced Kafka-based asynchronous claims and eligibility workflows, improving median response time by ~35%. Built a Kubernetes developer platform for clinical services; cut release cycles from hours to minutes using Helm and CI/CD pipelines. Deployed Prometheus, Loki, and Grafana dashboards with alerting tied to operational SLOs. Implemented zero-downtime deployments with canary releases and automated rollback scripts. Secured APIs with OAuth2/OIDC and fine-grained IAM; added rate-limiting and idempotency controls for critical operations. Optimized async I/O and PostgreSQL queries to sustain sub-50 ms p95 latency on key endpoints. Drove reliability culture via contract testing, chaos drills, and load tests; red
Senior Backend Developer (Python) at LCG, Inc
April 1, 2023 - April 1, 2023Built high-throughput Python and Go services for transaction logging and fraud detection with strict latency SLAs. Designed Kafka pipelines for near real-time alerts and immutable audit logs (SOC 2/PCI compliance). Engineered resilient data layers with PostgreSQL and Redis, maintaining sub-50 ms latency for financial workflows. Migrated legacy Java components into Python microservices, reducing infrastructure costs by ~60%. Established SRE practices — monitoring, on-call, incident playbooks, and postmortems — reducing downtime by ~40%. Automated deployments with Ansible, AWS CloudFormation, and Jenkins CI/CD. Implemented tracing with Zipkin and structured logs to speed root-cause analysis. Defined protobuf-based APIs and backward-compatible contracts for partner integrations. Built integration tests validating fraud-detection pipelines and service interfaces.

Developed shared Python libraries for authentication, retries, and metrics used by multiple teams. Optimized SQL queries and indexing; improved database throughput by ~40% on payment tables. Implemented rate limiters, circuit breakers, and idempotent APIs for safe and reliable transactions. Added monitoring and tracing using StatsD, Graphite, and ELK Stack; built dashboards for latency and success rates. Supported incident triage, postmortems, and security reviews meeting global compliance. Enforced API versioning and schema migrations for cross-team compatibility. Implemented canary deployments and shadow testing for safe production rollouts. Collaborated with SRE to optimize AWS EC2 infrastructure and auto-scaling policies.
Python Backend Developer at Mosaic
January 1, 2015 - January 1, 2015Designed and implemented a fund P&L distribution service with complete audit history. Developed a risk-profiling QA module for compliance scoring. Integrated third-party banking APIs for debit-card reissuance and tracking. Built asynchronous workers using Kafka and Celery for event-driven workflows. Implemented monitoring with Nagios, Graphite, and ELK Stack. Optimized data access via Redis and PostgreSQL, improving performance on high-traffic paths. Strengthened auth via OAuth2 and LDAP, enforcing least-privilege access. Automated builds and releases with Jenkins and Docker. Authored performance and regression tests ensuring latency targets pre-release.
