Mastering Large-Scale & AI System Design
Evolving from a code-centric engineer to a systems architect by mastering high-throughput distributed systems and the specialized infrastructure required for production-grade AI/ML.

The Architectural Gap
While my implementation skills were strong, I identified a bottleneck in my ability to architect systems. Transitioning into technical leadership required moving beyond writing clean code to managing complex state, consistency models, and the specific hardware-software interplay required for modern AI workloads.
Technical Deep-Dive
To close this gap, I executed a rigorous, multi-disciplinary study plan focusing on two fronts:
1. Distributed Systems Fundamentals
I moved beyond theoretical patterns to study real-world trade-offs in high-stakes environments:
- Storage Engines: Analyzing LSM-trees vs. B-Trees for write-heavy vs. read-heavy workloads.
- Consistency Models: Evaluating the operational cost of strong consistency vs. eventual consistency in global deployments.
- Observability: Implementing structured telemetry to identify bottlenecks in microservices architectures.
2. AI/ML System Design (The New Frontier)
Designing for AI introduces unique constraints that standard web architecture doesn’t cover. I focused on:
- Inference Optimization: Implementing model quantization and caching strategies to minimize P99 latency.
- Data Pipelines: Architecting feature stores and ETL pipelines that handle petabyte-scale datasets for training.
- GPU Orchestration: Understanding resource scheduling and memory management for distributed training clusters.
The Resulting Framework
System design is no longer a checklist; it is a discipline of Trade-off Analysis. My methodology now prioritizes:
- Hardware-Aware Software: Designing with an understanding of GPU/CPU interconnects and memory bandwidth.
- Operational Durability: Factoring in deployment strategies (Blue/Green, Canary) and graceful degradation from the initial design phase.
- Decision Documentation: Utilizing ADRs (Architecture Decision Records) to capture the why behind the what, ensuring long-term maintainability.
Looking Forward
As I continue learning, these skills allow me to bridge the gap between low-level performance and high-level system reliability.
