Engineering case studies,
browse like films.

Each project is a full case study — the problem, the architecture, and the decisions that made it hold. Shipped work and system-design concepts, clearly marked.

Featured

Distributed Compute Platform

A control plane built so the decision layer scales horizontally and stays fast — orchestrating millions of transactions across distributed compute without becoming the bottleneck.

Real work
1

Self-Healing Infrastructure

Failover that doesn't wait for a human

GEICO · Uber·Failover · Replication · Recovery-Oriented
ProblemWhen a node or service fails at 3 a.m., waiting for a person to notice turns a blip into an outage.
SolutionBuilt automation layers in Go on Kubernetes that detect failure, fail over, and restart services on recovery-oriented policies.
Impact99.98% uptime across 40+ production microservices at GEICO; 47% fewer cascading-failure incidents at Uber.
2

Linux Container Runtime Platform

One standard way to run a workload

GEICO · Uber·Containers · Scheduling · Standardization
ProblemEvery team running workloads its own way makes provisioning slow and operations inconsistent.
SolutionBuilt Linux-based container runtime management on Docker and Kubernetes schedulers to standardize workload orchestration.
Impact63% faster provisioning across 500+ containerized service instances at GEICO; 47% faster deployments across 20+ services at Uber.

Fault-Tolerant Kafka Pipeline

500K+ events a second, nothing lost

GEICO · Uber·Replication · Cross-Region · Delivery Guarantees
ProblemA pipeline moving hundreds of thousands of events a second can't drop data when a broker or a region has a bad day.
SolutionBuilt Kafka event pipelines with replication and synchronization across regional clusters, tuned for delivery guarantees.
Impact500K+ events/sec at 99.97% delivery reliability with zero data loss at GEICO; sub-5 second propagation at 99.94% at Uber.
4

Observability Stack

From “something's wrong” to root cause

GEICO · Uber·Tracing · Telemetry · Incident Response
ProblemIn a distributed system, an alert that says “slow” without saying where costs hours.
SolutionBuilt observability on OpenTelemetry and Datadog APM with custom dashboards and alerting, then closed the loop with runbooks and RCAs.
Impact51% lower MTTR across 8M+ monthly requests at GEICO; 43% and 39% fewer repeat incidents at GEICO and Uber.
5

Terraform & Helm IaC Suite

Environments you can rebuild from a commit

GEICO · Uber·Infrastructure as Code · Reproducibility · Automation
ProblemHand-built environments drift, and every new one is a day of manual, error-prone work.
SolutionBuilt Terraform and Helm automation suites that describe infrastructure and service releases as reviewed, versioned code.
Impact58% less provisioning and management overhead across 30+ services at GEICO and 20+ at Uber.
6

Load & Fault-Injection Framework

Break it on purpose, before production does

GEICO · Uber·Load Testing · Fault Injection · Brown-Out Testing
ProblemSystems that pass functional tests can still fall over the first time a dependency slows down or load doubles.
SolutionBuilt load, performance, and fault-injection test frameworks in Python and Go to find scaling limits and failure modes early.
ImpactSurfaced 23 critical scalability bottlenecks at GEICO and 15 critical infrastructure vulnerabilities at Uber before they hit production.
7

Multi-Tenant Security & Compliance

Isolation and audit trails built into the platform

GEICO · Uber·Encryption · RBAC · Audit Logging
ProblemOn a shared platform, one tenant's data and permissions have to stay invisible to every other tenant — and provably so.
SolutionApplied multi-tenant security controls: encryption, RBAC access policies, and compliance audit logging with documented remediation.
ImpactProtected 500M+ monthly records at GEICO and $2.1B in annual transaction volume at Uber.

Concepts & explorations

System design

How I'd approach classic problems — designs and explorations, not shipped products. Marked as concepts so nothing here pretends to be more than it is.

Concept

Real-time Analytics Pipeline

From raw events to live dashboards

System design·Event-Driven · Stream Processing · Real-Time
ProblemDashboards need fresh numbers, but re-querying raw events every time is too slow.
SolutionAggregate events in a streaming layer and serve pre-rolled metrics.
ImpactDashboards read pre-aggregated rollups instead of scanning raw history.
Concept

API Gateway Platform

One front door for many services

System design·Routing · Auth · Limits
ProblemEvery service re-implementing auth, limits, and logging is duplicated risk.
SolutionA gateway that owns cross-cutting concerns once, in front of everything.
ImpactServices focus on their domain; the edge handles the shared machinery.
Concept

Log Aggregation & Search

Find the one line that explains the outage

System design·Ship · Index · Query
ProblemLogs scattered across a hundred machines are useless during an incident.
SolutionShip every log to one place, index it, and make it searchable in seconds.
ImpactDuring an outage, the answer is one query away instead of a hundred SSH sessions.
Experience

Two seasons of building things that had to stay up.

Architect and operate distributed compute and infrastructure platforms for enterprise-scale workloads. The work spans a Java 21 control plane orchestrating 8M+ daily transactions at sub-18ms p95, Go and Kubernetes automation that keeps 40+ production microservices at 99.98% uptime, a Linux-based container runtime platform across 500+ service instances, and the Kafka, observability, IaC, and security layers that make it all reliable — alongside SRE and platform teams in Agile sprints.

01
Problem

Enterprise-scale transaction volume needed a compute platform that could scale horizontally without the orchestration layer becoming the bottleneck.

Solution

Architected a horizontally scalable Java 21 distributed compute platform with a control plane and distributed state management, handling 8M+ daily transactions at sub-18ms p95.

02
Problem

Failures in production microservices depended on people noticing and responding, stretching outages and risking cascades.

Solution

Engineered a self-healing automation layer in Go on Kubernetes — automatic failover, replication, and recovery-oriented restart policies — delivering 99.98% uptime across 40+ microservices.

03
Problem

Provisioning and running workloads varied by team, slowing delivery and making operations inconsistent across hundreds of services.

Solution

Built a Linux-based container runtime management platform on Docker and Kubernetes schedulers, standardizing orchestration across 500+ containerized instances and cutting provisioning time by 63%.

04
Problem

Event data had to move at very high volume across regions without loss, and incidents had to be understood and repaired quickly.

Solution

Developed a fault-tolerant Kafka pipeline (500K+ events/sec, 99.97% delivery, zero data loss guarantees) and an OpenTelemetry + Datadog APM observability stack that cut MTTR by 51%.

Experiments you can actually run.

Small, honest demos of the patterns behind the work — a token-bucket limiter, exponential backoff, a cache — running right here in your browser. Plus the deeper case studies they come from.

About

I build for the day it breaks — not the day it demos.

Most software works on the happy path. I spend my time on the other one — the 3 a.m. spike, the retry storm, the dependency having a bad day. The systems I'm proud of aren't the ones that never fail; they're the ones that fail in ways you can see, contain, and recover from.

That turns into a way of working. I start from the failure and design backward, so the good day takes care of itself. I'd rather ship something simple and correct than clever and occasionally wrong. And I try to leave every system more legible than I found it — explicit states, honest names, runbooks that actually get used — so the next engineer, or the next on-call, can move without fear.

How I work01 / 05
Principle 01

Design from the failure backward

Start at what breaks under load, then work back to the architecture. The happy path takes care of itself.

Let's build something that stays calm when traffic doesn't.
