A few engagements we're proud of. Some clients named, some under NDA, numbers kept real either way: happy to walk through the details on a call.

Cloud spend cut 50%, 24,000 errors a day eliminated

The problem. A carbon accounting platform was outgrowing its infrastructure: a rising cloud bill, thousands of daily database errors, and data pipelines held together by an external scheduler.

What we built. We led backend engineering across an integration-heavy platform: accounting system and energy data integrations, real-time ingestion on distributed task queues, and scheduled pipelines migrated to serverless functions.

  • Cloud costs halved through database right-sizing, query optimization, and 36 missing indexes
  • Around 24,000 daily SQL errors traced to a single lookup bug and eliminated
  • Database reads cut from 67M to under 20M per month
  • P99 database CPU brought back to baseline

Event-driven microservices moving money at scale

The problem. A global invoicing and payments platform needed high-throughput payment flows that stayed reliable as the number of services grew.

What we built. We designed and built Python microservices with FastAPI and async I/O, connected by Kafka event streams, with strict schema contracts and full observability: distributed tracing, metrics, and dashboards.

  • High-throughput payment and invoicing flows in production
  • Services decoupled via Kafka event streaming
  • Distributed tracing and Grafana dashboards for incident diagnostics
  • Automated test coverage across unit, integration, and contract tests

Bookkeeping automated across QuickBooks, Xero, and on-chain data

The problem. A crypto invoicing startup needed accounting data flowing between blockchains and traditional bookkeeping tools, reliably and in real time.

What we built. We built backend services and REST APIs for invoice generation and bookkeeping automation, with event-driven pipelines syncing third-party financial APIs and real-time wallet transaction ingestion.

  • Real-time blockchain wallet transaction fetching
  • Two-way sync with QuickBooks and Xero
  • Performance bottlenecks resolved under high transaction load

Two consumer mobile products, idea to app store

The problem. Two products needed building end to end: a news app for the Albanian market and a community platform for an organization with more than 500 members.

What we built. We designed, built, and shipped both apps cross-platform with React Native: a news aggregator, Buletin, that summarizes and groups stories by topic, and a community platform mapping member interests and skills.

  • Both apps shipped to iOS and Android
  • News from every major Albanian source, grouped by topic
  • Collaboration efficiency up 25% for a 500+ member community
