Abdulrahman Khalid Ibrahim
Senior Software Backend Engineer
Senior Software Backend Engineer with 5 years building and operating high-throughput, low-latency distributed systems in production. Deep expertise across Go, TypeScript/Node and Python with a strong reliability mindset — mission-critical service ownership, incident root-cause analysis, and scaling backends for 10x growth. Hands-on production experience integrating AI/LLM systems (OpenAI SDK, CrewAI, RAG with Qdrant/pgvector, MCP) into real engineering workflows.
Experience
Senior Backend Software Engineer · SoumJan 2026 — Present
- Rolled out OpenTelemetry + SigNoz across 15+ microservices — unified traces, metrics and log correlation, closing long-standing cross-service debugging gaps and reducing mean time to detection.
- Shipped the post-payment NPS system end to end — event schema, ingestion, aggregation and product surfaces — documented with Mermaid specs adopted as a team standard.
- Own backend services in the Car category, a high-value expansion vertical — pricing/summary calculation and listing flows.
Senior Backend Engineer, AI Lead · GoalngoFeb 2026 — Present
- Architected and shipped Gino (Goalngo Mind), the platform's AI agent — ingests user profiles and activity to generate AI-driven talent reports for coaches, intent-based actions and personalized fitness plans.
- Built semantic retrieval on PostgreSQL + pgvector with multi-LLM serving — OpenAI in production plus a self-hosted local-LLM path for cost control and data residency.
- Reinforced production stability on return, resolving several long-standing production bugs.
Senior Backend Software Engineer · VxLabsMar 2025 — Jan 2026
- Designed and operated high-throughput telemetry pipelines (MQTT → Kafka → Elasticsearch) processing 1M+ events/day, tuned for low latency and fault tolerance.
- Led cloud-native services in a Turborepo monorepo, enforcing Clean Architecture and DDD boundaries across production systems.
- Built multi-tenant SaaS provisioning and lifecycle workflows, converting on-prem systems into a scalable cloud platform.
Senior Backend Engineer · GoalngoOct 2023 — Mar 2025
- Led migration of high-traffic backend services from AWS Lambda to Kubernetes using the strangler pattern, improving availability and scalability for 60k+ MAU.
- Optimized feed and ranking pipelines with fan-out and batching strategies — ~90% throughput improvement under peak load.
- Designed event-driven services on RabbitMQ for user actions, notifications and background processing; cut deploy and rollback times 65% via container and CI/CD optimization.
Senior Software Engineer, Backend · CMPNov 2023 — Mar 2025
- Architected services and REST APIs on DDD + Clean Architecture with maintainable module boundaries.
- Built resilient, idempotent RabbitMQ consumers with guaranteed delivery; producers used the outbox pattern for fault tolerance.
- Implemented real-time chat synchronization across web dashboards with SignalR.
Software Engineer (Fullstack) · ProCrewNov 2021 — Oct 2023
- Built and shipped Python/FastAPI backend services across multiple SaaS platforms — AI prediction, insurance marketplaces and productivity tools — owning REST API design, data modeling, persistence and integration testing.
- Integrated Bayesian ML prediction services into production APIs for weekly sports lineup optimization — model serving, request batching and accuracy monitoring.
- Designed data pipelines and persistence across PostgreSQL, MongoDB, Firestore and Redis, applying Clean Architecture for testability.
