Golang Software Engineer
April 2024 – Present
Worked across multiple production backend services including a multi-channel notification platform, profile search indexing, fiscal receipt processing, domain validation, and internal dictionaries. Contributed both at the architectural level through RFCs/ADRs and at the implementation level across distributed services built in Go.
- Developed and maintained a multi-channel notification system (email, SMS, FCM, HMS), contributing to both channel services and the central routing service.
- Built an APR proxy service integrating with external SOAP APIs.
- Implemented a fiscal receipts service (NPD) handling OCR ingestion, MongoDB storage, S3 image persistence, and analytics via Change Streams.
- Designed and implemented Meilisearch synchronization for profile entities via NATS, including tenant-based search token issuance.
- Developed a user synchronization service integrating Profiles with Keycloak and managing external identity mapping.
- Implemented a domain checker service using WHOIS lookups.
- Built a dictionaries service with item relationships, normalization, and validation logic.
- Authored RFCs and ADRs for selected services to standardize architecture and communication patterns.
