Re-Architecting a Payments Core for Linear Scale

We decomposed the ledger into an event-sourced core on an append-only PostgreSQL event store partitioned by merchant, with idempotent command APIs and Redis projections, replacing pessimistic locks with optimistic concurrency.

900→12k TPS — Sustained throughput
840ms→64ms — p99 latency
0 — Reconciliation drift

A mid-market healthcare analytics company under HIPAA and SOC 2.

Lift, Re-Platform, and Optimize for a Healthcare Data Provider

We ran a phased strangler-pattern migration to AWS, shifting traffic per service behind a routing layer with per-service rollback. All infra was Terraform-defined with encryption by default and audit logging mapped to SOC 2…

9 months — Zero-downtime migration
−38% — Infrastructure cost
0 findings — SOC 2 Type II

"They moved our entire platform under us and our customers never felt a thing." — Marcus Lindqvist, VP of Infrastructure

B2B SaaS / Collaboration
An early-growth B2B SaaS whose single-tenant pilot landed three enterprise accounts.

Multi-Tenant Re-Platform for a B2B Collaboration Product

We re-architected to multi-tenant with row-level isolation, per-tenant encryption keys, and a self-service provisioning service, rebuilding the frontend in Next.js and adding tenant-scoped metering for billing.

2 wks→10 min — Tenant provisioning
6→40k — Paid seats in 14 mo
3/3 — Security reviews passed

"The platform stopped being the bottleneck to enterprise deals — it became the reason we won them." — Sophie Aldridge, Co-Founder & CEO

Media / Consumer streaming
A venture-backed streaming startup with spiky viewership.

FinOps and Reliability Engineering for a Consumer Streaming App

We instrumented cost and performance telemetry, moved stateless workloads to Kubernetes with demand-driven autoscaling and Spot pools, added multi-tier caching, and codified capacity policies in Terraform.

−44% — Monthly cloud spend
5/wk→<1/mo — Surge incidents
99.99% — Peak-event uptime

"We halved the bill and stopped getting paged at 2am — I didn't think we could have both." — Reuben Castellanos, Head of Platform

Enterprise software / Customer support operations
An enterprise B2B software company fielding 30,000+ monthly tickets.

Retrieval-Grounded AI Automation for an Enterprise Support Operation

We built a retrieval-grounded agent over the client's docs with strict citations and confidence-gated escalation, integrated through a typed tool layer for scoped account actions, validated in shadow mode against 20,000…

61% — Tickets auto-resolved
14h→<2min — First response
−52% — Cost per ticket
