What I'm looking for

I am looking for a role that challenges me technically and offers opportunities for mentorship and leadership.

As a Backend Developer with over 4 years of professional experience, I have honed my skills in building scalable and resilient backend systems primarily using Go. My journey has taken me through both startup and enterprise environments, where I have thrived in remote and on-site roles, collaborating with diverse teams. In the last two years, I have stepped into senior and leading positions, where I not only guided architectural decisions but also mentored team members to foster a culture of continuous improvement.

At beyim.ai, I upgraded our event delivery system to NATS JetStream, significantly enhancing real-time tracking capabilities. My efforts in optimizing our AI content job queuing with Redis Streams led to a remarkable boost in throughput during peak hours. I also implemented advanced testing strategies using K6 and Grafana, ensuring our systems could handle 10x scale. My commitment to efficiency is evident in my work, such as integrating Bloom filters into our quiz engine, which reduced database reads by 60% for duplicate checks.

Previously, at INXY Payments, I introduced distributed tracing with OpenTelemetry and Jaeger, which helped identify bottlenecks and reduce bugs by 20%. My technical acumen extends to optimizing gRPC balancers and configuring logging systems, which have resulted in significant cost savings and performance improvements. I am passionate about leveraging technology to solve complex problems and am always eager to take on new challenges that push the boundaries of what is possible.

Upgraded to NATS JetStream for persistent, real-time event delivery in student activity tracking. Switched to Redis Streams for faster AI content job queuing, boosting throughput during peak hours. Used K6 + Grafana to test for 10x scale, optimizing load thresholds. Added Bloom filters to the quiz engine, cutting DB reads by 60% for duplicate checks.

Introduced distributed tracing (OpenTelemetry + Jaeger), identifying bottlenecks and reducing bugs by 20%. Switched from the default gRPC balancer to Consul + Envoy, lowering API Gateway load. Configured Loki + Promtail to replace the ELK stack, cutting log storage costs by 5x. Separated event processing into hot and cold paths, speeding up critical flows (e.g., payments).

Optimized data serialization in Protocol Buffers, reducing message size by 15.6%. Implemented connection pooling for gRPC, decreasing overhead from connection establishment. Tuned batch.size and linger.ms configurations, improving Kafka producers' throughput. Configured keepalive parameters for long-lived connections, which reduced call latency.
