Muhammad Faisal Affan

Dear Hiring Team,

I am writing to express my strong interest in the Solutions Architect / Senior Platform Engineer position. With over 8 years of software engineering experience specializing in high-throughput Go microservices, Kubernetes platform design, distributed event streaming, and resilient banking architectures, I am confident in my ability to make an immediate impact on your engineering organization.

Throughout my career, I have thrived on taking end-to-end ownership of mission-critical systems. In my current role at Bank Mandiri, I serve as Solutions Architect (KOPRA), architecting active-active multi-site platforms and Kafka stretch cluster streaming for 15M+ merchants with a target capacity of ~210,000 TPS. Previously at BTPN Syariah, I served as the sole architect and backend engineer for two mission-critical banking products serving 4.1M+ customers. I built an offline-first micro-finance platform solo in 30 days, which reduced loan approval times from 7 days to under 24 hours, and designed an ISO 8583 bridge for the mobile banking app Sitepat (10K+ downloads) that slashed balance inquiry times from 30 minutes to under 2 seconds while maintaining a 99.7% uptime SLA.

My technical expertise is paired with a strong focus on platform resilience, system observability, and cost optimization. I am an AWS-certified solutions architect with deep production experience in OpenShift/Kubernetes clusters, ArgoCD GitOps, and unified telemetry systems using the LGTM (Loki, Grafana, Tempo, Mimir) and VictoriaMetrics stack.

I am eager to bring my background in high-performance fintech architectures and containerized cloud platforms to your company. Thank you for your time and consideration. I look forward to the possibility of discussing how my experience aligns with your team's technical goals.

Sincerely,
