About

Work Snapshot: - Built a secure opaque-token issuance and verification system along with a complete client-onboarding API - Implemented an event-gateway buffering system to decouple deployments from upstream services, ensuring no upstream traffic is lost and all events are processed without failure - Working on implementing customized APIs around Exotel's Voice APIs, Messaging APIs while enhancing the offerings of cloud telephony API suite by Exotel Tech Stack: Languages --> Go, Python, C++, Rust Libraries/Crates/Modules --> serde, tokio, tonic (Rust ecosystem); go-redis, zap, go-co-op/gocron/v2, aws-sdk-go-v2 (Go ecosystem) DB drivers --> pgx (in golang) Cache & DB --> Redis, MySQL, Cassandra ORMs --> GORM, Diesel others --> git, Docker, pprof, OpenTelemetry, Jaeger, Prometheus, Grafana/Loki, Bash Scripting

Team: co-creation
Developed an automated call-campaign creation workflow for IDFC Bank by integrating their OAuth access_token generation API along with AES-256 encrypted Mule Data Query API (ensuring secure encryption of request payloads and proper decryption of responses) and then triggering AWS Lambda executions to add contact-lists and to handle call campaign logic. Scheduled four distinct daily cron jobs (one for each BU) using the go-co-op/gocron/v2 scheduler
Built REST APIs for a doctor’s appointment booking system. An automated daily call-campaign creation service ingests appointment data and dynamically triggers outbound calls to patients to reconfirm the appointment status via integrated telephony APIs by Exotel.
Created a Passthru in the IVR flow to integrate the client's callback appointment confirmation API, triggered when a patient presses the button for appointment confirmation, to send real-time confirmation updates to the client
Instrumented OpenTelemetry for end-to-end error tracing across http handlers, services, repositories, and background jobs, exporting http events, error traces to Jaeger for real-time visualization of API request flow across different service layers.
Working on integrating Manage Engine's Ticket Creation and Updation APIs along with Zoho's access_token generation API whenever a call occurs.
Developed a high-throughput system to automate the daily migration of over 100K inbound and outbound call records, including MP3 call recordings, for HDFC Bank.
