Senior Software Development Engineer | Java & Scala | AWS & Microservices | API INTEGRATION

I am a senior backend engineer with deep expertise in designing, building, and scaling high-performance backend systems for SaaS products, data platforms, and API-driven businesses. I specialize in distributed systems, microservices, and data pipelines that handle large volumes of traffic and data with reliability and security.

My core backend stack includes Java, Scala, and PHP, with strong experience building RESTful and GraphQL APIs using Spring Boot, Spring Cloud, and modern API gateway architectures. I have worked extensively with microservices, service discovery, rate limiting, authentication, OAuth, and API security, designing systems that are resilient, fault-tolerant, and production-ready.

I have strong experience in API integrations and data ingestion pipelines, especially for marketing, e-commerce, and analytics platforms. I have built and maintained integrations with Shopify, Facebook Ads (Meta), Google Ads, and Appsflyer, handling complex data models, pagination, incremental syncs, and error-tolerant retries. I specialize in building ETL and ELT pipelines that pull data from third-party APIs, transform it, and load it into data warehouses or internal systems with accuracy and consistency.

I am highly skilled in event-driven and asynchronous architectures using Kafka, queues, and background workers, enabling systems to scale while keeping latency low. I design systems with CQRS, idempotency, retries, backoff strategies, and dead-letter queues to ensure reliability even when external APIs fail.

My database expertise includes PostgreSQL, MySQL, and NoSQL stores like Redis, where I design schemas, indexes, caching strategies, and consistency models to support high-throughput applications. I have deep experience using Redis for caching, session storage, rate limiting, locks, and real-time presence systems.

I work heavily in cloud-native environments and have built systems using Docker, Kubernetes, AWS, and CI/CD pipelines. I focus on observability and reliability using logging, metrics, alerting, and tracing to keep production systems stable.

From a software design perspective, I focus on clean architecture, SOLID principles, domain-driven design, and scalable system design. I have designed API gateways, authentication systems, multi-tenant SaaS platforms, and data synchronization engines that support thousands of customers.

I also bring strong experience in testing and quality engineering, including unit tests, integration tests, and API mocks, ensuring systems remain stable as they grow. I am comfortable working with Google Ads API, GraphQL APIs, REST APIs, and large SDKs, including mocking and validating complex integrations.

I work closely with product and data teams to turn business requirements into reliable backend systems. Whether you need a new API, a data pipeline, an integration, or a system redesign for scale, I bring a production-focused, startup-friendly engineering mindset that delivers results quickly and safely.
