Work

Client delivery, not a catalog.

Anonymized until we have permission to name names. Each story is a problem, what we built, and what changed.

01 — Cloud migration

Confidential software platform

From a hand-managed VPS to EKS, without taking the product down

Business result

production kept running through the cutover; capacity and cost now follow traffic.

Situation
The product platform ran on a manually managed VPS and needed a controlled move to automated cloud infrastructure.
Firebrik’s responsibility
Moved the product platform to Kubernetes on AWS EKS and implemented the deployment, scaling, event, and event-sourcing foundations.
Constraints
The production product had to remain available throughout the cutover; the client name remains confidential.

Architecture and delivery

Moved a company’s operation of the entire product platform off a manually managed VPS onto automated Kubernetes on AWS EKS. Zero-downtime deploys, autoscaling, scale-to-zero for cost, Kubernetes events, and event sourcing as the backbone. They went to the cloud. The name stays off the page.

100%Uptime through cutover

Availability observed through the production cutover; no maintenance window was introduced.

02 — Same-day delivery platform

Confidential same-day prescription delivery platform

Prescription delivery without in-house drivers

Business result

same-day delivery as a product, without standing up a private fleet.

Situation
Businesses needed to offer same-day prescription delivery without operating their own driver fleets.
Firebrik’s responsibility
Built the courier-network integration and live rate-selection workflow across multiple external courier APIs.
Constraints
The platform coordinated several external systems and had to present current courier options at order time.

Architecture and delivery

Built the courier-network integration for a platform that orchestrates same-day prescription delivery. Companies without their own drivers could pick external couriers at order time, with live rates from multiple courier APIs. AWS serverless, event-oriented, talking to several external systems. Client unnamed.

MultiCourier rate comparison

The delivered workflow compares live rates from multiple courier providers during order placement.

03 — A City’s Metropolitan Archives

A city’s metropolitan archives

1,000 years of archives, searchable in under a second

Business result

the archive team can serve records instantaneously instead of through a slow lookup.

Situation
Digitized holdings spanning 1,000 years needed to become immediately searchable rather than remain a slow lookup process.
Firebrik’s responsibility
Made archive metadata and extracted content indexable, filterable, and available through a sub-second search experience.
Constraints
The search had to work across heterogeneous digitized records, metadata, and extracted content accumulated over a millennium.

Architecture and delivery

For a city’s metropolitan archives, digitized holdings spanning 1,000 years were made searchable: metadata, extracted content, indexed and filterable, so a query comes back in sub-second time and anyone who needs the record can have it immediately.

< 1.0sSub-second archive query

Search queries across the indexed archive returned in under one second.

04 — Multi-tenant SaaS core

Growing multi-tenant SaaS platform

Tenant isolation without sacrificing product velocity

Business result

stronger isolation and a predictable path for onboarding and scaling tenants.

Situation
Tenant growth required stronger isolation without slowing product delivery or making operations unpredictable.
Firebrik’s responsibility
Designed the hybrid schema-isolation engine, explicit tenant context, safe background-work patterns, and operational tooling.
Constraints
Isolation had to cover request handling and asynchronous work while preserving an efficient onboarding path.

Architecture and delivery

Designed a hybrid schema-isolation engine with explicit tenant context, safe background work, and operational tooling for a growing SaaS platform.

HybridSchema isolation model

The delivered model combines isolation boundaries with shared operational tooling; this is an architecture descriptor, not a performance metric.

05 — Monolith decoupling

Confidential high-traffic software product

A controlled cutover with no maintenance window

Business result

independent deployment without a risky big-bang rewrite.

Situation
A high-traffic workflow needed independent deployment without a disruptive big-bang rewrite.
Firebrik’s responsibility
Separated the workflow behind stable contracts and introduced shadow traffic, observability, and controlled migration checkpoints.
Constraints
The existing product had to stay live while behavior moved behind the new boundary.

Architecture and delivery

Separated a high-traffic workflow behind stable contracts, shadow traffic, and observable migration checkpoints while the existing product stayed live.

ZeroMaintenance window

The production cutover completed without scheduling a maintenance window.
