Lead a cross-functional team of 8 (2 business analysts, 2 backend engineers, 2 frontend engineers, 1 QA engineer, 1 DevOps engineer) building an e-commerce platform from the ground up, owning delivery end-to-end. •​ Run daily stand-ups, sprint planning, and retrospectives; translate analysts' requirements into technical specs the backend and frontend squads can build against. •​ Decoupled frontend and backend workstreams by introducing mocked API contracts, letting UI development continue in parallel while backend integrations were finalized. •​ Reworked the core data model to resolve schema conflicts between backend and analytics requirements, unblocking parallel work across sub-teams. •​ Set up direct channels between previously siloed sub-teams, cutting handoff delays and keeping feature delivery on schedule.

Project: LLM-powered competency assessment platform (HR-Tech) •​ Designed a 5-microservice architecture (Go, gRPC) for an LLM-based competency assessment system. •​ Built an LLM Gateway with Redis caching, rate limiting, and a circuit breaker, cutting paid LLM API calls by 40%. •​ Tuned PostgreSQL (connection pooling, indexing, partitioning) to sustain 5,000 RPS at <50ms p95 latency. •​ Set up CI/CD (GitHub Actions) and observability (Prometheus, Grafana); kept unit-test coverage at 85%.

•​ Built Lock-and-Mint smart contracts (Solidity) and a Go backend orchestrator for event monitoring and transaction management. •​ Added multi-signature approval for critical operations and an alerting system; supported 100+ cross-chain transactions/hour. Project: Logistics OLAP platform (data engineering) •​ Built a Go + Apache Airflow ETL pipeline processing 1M+ events/day. •​ Re-modeled ClickHouse schema and queries (partitioning, materialized views), cutting analytical report runtime 12x. Project: Third-party REST API integration (retail) •​ Built an async integration service using worker pools, exponential-backoff retries, and a PostgreSQL-backed dead-letter queue.

•​ Built the core mortgage-application processing engine, integrating with credit bureaus and legacy ERP systems. •​ Built OCR-based document validation, rate-calculation, and PDF report-generation modules. •​ Optimized SQL queries and schema, cutting processing time for key operations by 25%.

•​ Designed and built the backend for an analytics platform, integrating with SAP via RFC/BAPI interfaces. •​ Cut complex report-generation time by 35% through query optimization and parallel processing.

•​ Built ETL pipelines consolidating Oracle DB data across 8 regional markets. •​ Built REST APIs for sales-metrics access; automation cut data-prep time by 40%.
