Experience
AlumaOct 2025–Mar 2026
Platform Software Engineer · Cambridge, UK (mainly remote)
- Hired in this role to help the company trim computing costs, enhance reliability and bring networks
expertise to projects with potential clients.
- Redesigned network topologies handling a GB of structured data daily, e.g. gcp-to-site IPsec VPN
connecting, including enforcement of safe handling of psk keys.
- Optimized Go services by reducing memory overhead, redundant network calls and object download latency,
enabling smaller compute instances and lower infrastructure costs.
- Reshuffled parts of the system architecture to bring redundancy for same-region outages and database auto failovers.
BlacklaneMar–Sep 2025
Site Reliability Engineer · London / Berlin (hybrid)
- Got tasked to reduce latency impacting clients finishing their books. Profiled the architecture and network calls, pinning the underlying issue to an overuse and hitting limits on aws dns resolution. Fixed the issue by exposing services in-cluster and changing applications to rely on
- Migrated an undocumented bare-metal service to Kubernetes, standardising its deployment and operational
lifecycle.
- Built a Terraform provider in Go that made data from multiple internal systems available to engineering
teams through Terraform configurations.
Cutover2021–2024
Senior Platform Engineer / SRE · London, UK (hybrid)
- Provisioned and managed infrastructure across 8 AWS accounts using Terraform, with dedicated accounts for
customers requiring isolated environments.
- Built private log ingestion paths using AWS Transit Gateway and VPC routing, keeping customer log traffic
off the public internet.
- Architected a ~100-node Kubernetes platform serving 40 customer tenants, combining sandboxed runtimes,
node isolation and network controls to enforce tenant boundaries.
- Automated Kubernetes environment provisioning through Slack and Argo CD, reducing lead time from
approximately one week to four hours for ~40 engineers.
- Built EC2 deployment workflows using AWS Step Functions and Lambda to update launch templates and trigger
rolling instance replacements through Auto Scaling Groups.
- Led P0 incident response and introduced SLOs and postmortem practices across engineering teams.
Catawiki / Salonized2020–2021
Senior Platform Engineer / SRE · Amsterdam, Netherlands
- Reduced P95 booking query latency from multiple seconds to under one second through database schema and
indexing changes.
- Established a test-gated GitOps release process, using GitHub Actions for validation and automated Argo CD
manifest updates after merge.
Creditas2017–2019
Senior Software Engineer · São Paulo, Brazil
- Reengineered a Ruby loan-pricing system handling ~200K requests/day, implementing financial calculations
involving fixed-point iteration, based on “spreadsheet” models.
- Built its production infrastructure on AWS using ALB, WAF and ECS, validating the new implementation
through automated tests and A/B testing.
- Reduced memory consumption to lower the required instance count and improve application gross margin;
implemented graceful degradation to maintain responsiveness under heavy load.
