• Built a retrieval-augmented WhatsApp support agent (Azure OpenAI + ChromaDB, per-tenant isolation) with an automated web-crawl → chunk → embed ingestion pipeline and confidence-gated human escalation. • Built the backend for an autonomous AI SEO content agent in a multi-tenant e-commerce platform, orchestrating an LLM microservice to generate catalog-aware, market-targeted blog articles that auto-publish to merchant storefronts. • Designed a unified payment-gateway abstraction in Java/Spring Boot integrating 5+ providers including Razorpay, PayU, Cashfree, PhonePe and PayPal, allowing merchants to configure payment providers without code changes. • Built the Kafka order sync consumer that pushes order events to merchant webhooks, with 5 concurrent listeners, retries, and a dead letter topic, backed by a per store webhook configuration service and a payload transformer for per merchant formats. • Built secure server-to-server webhook processing with HMAC signature validation and idempotent charge handling to prevent duplicate order fulfilment during callback retries. • Engineered asynchronous transactional file-processing workflows for POS inventory systems, resolving data-race issues during concurrent high-volume updates. • Designed Elasticsearch SKU indexing and an event-driven Kafka pipeline processing ~100K records/day for fast and consistent cross-system catalogue lookups. • Built a multi-country address configuration system supporting 140+ countries with country-specific fields and validation for localized checkout and shipping workflows.

About

Software Engineer | Java Backend | Spring Boot | Microservices | Kafka | AWS I'm a Software Engineer with 1.2+ years of experience building production backend systems using Java, Spring Boot, Microservices, PostgreSQL, Kafka, Elasticsearch, and AWS. At Shoopy, I work on business-critical backend systems involving payments, concurrency, event-driven processing, search, and analytics. Some of the systems I've worked on include: • Designed a unified payment gateway abstraction integrating 5+ payment providers • Built idempotent webhook processing with HMAC validation to prevent duplicate order fulfilment • Designed an event-driven Kafka pipeline processing ~100K records/day • Worked on concurrency-safe file processing and transactional workflows • Built Elasticsearch-based SKU indexing for fast catalogue search • Built a Spring AI/RAG analytics service for querying transactional business data My core backend stack includes Java, Spring Boot, Spring Security, REST APIs, Microservices, Kafka, PostgreSQL, MySQL, Elasticsearch, Docker, Kubernetes, and AWS. I enjoy solving problems around distributed systems, backend architecture, scalability, concurrency, and system reliability. Currently open to SDE / Backend Engineer opportunities, particularly roles involving Java, Spring Boot, distributed systems, and scalable backend engineering.
