Professional experience:
Jun.2025 - Present
Software Engineer - Dhiraagu Plc, Male', Maldives
- Built an integration middleware layer between core APIs (CBS billing system,
  CRM, inventory management), exposing RESTful APIs for service inventory,
  balance adjustments, and lifecycle management. Implemented an API aggregation
  layer and a Redis-style cache layer that reduced call latency by ~40%.
- Built an AI-powered document generation service with a React TypeScript
  frontend (TanStack Router/Query, Jotai, Tailwind CSS, shadcn), integrated
  into HR systems and backed by Redis for conversation history management.
- Architected microservices and event-driven systems processing 6+ million
  daily messages via RabbitMQ, ensuring high availability and fault tolerance.
- Built a comprehensive observability platform with the LGTM stack: Loki for
  centralized log aggregation, Tempo for distributed tracing, Mimir for
  high-volume metrics, and Grafana for unified visualization — enabling
  end-to-end request tracing and rapid debugging across multi-service systems.
- Built the reverse-proxy layer for multiple production applications using
  Caddy, automating the full TLS certificate lifecycle via Cloudflare DNS and
  handling service routing and SSL termination.
- Served as primary technical liaison for third-party vendor API gateway
  integration with core systems.
- Built a Kafka event consumer for the Huawei CBS billing platform, processing
  10+ real-time event types (subscriber activations, recharges, billing
  transactions, offering lifecycle changes, threshold notifications) and
  routing events to downstream systems for automated processing and reporting.
- Deployed and optimized LLMs using llama.cpp with model quantization for
  efficient low-resource deployment.

Jan.2022 - Jun.2025
Software Developer - Dhiraagu Plc, Male', Maldives
- Optimized API performance by 30x through asynchronous processing with
  RabbitMQ and the Hangfire job scheduler.
- Containerized applications using Docker with orchestration via Compose,
  Swarm, and Kubernetes pod management across production environments.
- Developed the ESME API for USSD gateway integration and built a testing
  simulator for multiple service numbers using Python and NiceGUI.
- Deployed and scaled Mayan EDMS and KYC application to handle 10,000+
  documents per day.
- Resolved PostgreSQL database bloat, reclaiming 40GB through index
  optimization and automated vacuuming procedures.
- Maintained a Java-based message consumer bridging JMS queues to RabbitMQ for
  reliable inter-service communication.
- Developed a real-time network data scraping solution using Playwright,
  exposing internal APIs for system integration.
- Authored technical documentation for integration procedures and development
  best practices.
