Professional Summary
Senior Software Engineer with 10 years of experience spanning product engineering, platform infrastructure, and site reliability — operating at scale at companies like Zalando and Delivery Hero. I have a strong foundation in distributed systems and backend engineering, and a track record of owning high-impact work across the full stack: from ML-powered ranking systems and real-time delivery infrastructure to edge networking, Kubernetes platform tooling, and reliability programmes across large engineering organisations.
I'm at my best working on complex, ambiguous problems at the intersection of software engineering and infrastructure, where system design decisions have direct product and business consequences.

Engineering Experience
Global food and grocery delivery platform operating across 70+ countries, processing millions of orders daily.
Senior Software Engineer — Logistics, Deliveries Tribe (Jul 2025 - Present)
The Deliveries tribe owns the systems coordinating real-time delivery at global scale — a domain combining high traffic, strict reliability requirements, and a mix of legacy and modern systems serving millions of orders worldwide.
- Took ownership of core delivery flow architecture, identifying and resolving deep-rooted reliability issues that had been causing order losses across multiple markets.
- Designed and shipped a geospatial system to detect mall entrances, directly improving courier routing accuracy and cutting delivery times and operational costs at scale.
- Conceived and built automated phone-call agents that let couriers resolve delivery issues independently, eliminating language barriers and removing a persistent source of operational friction across international markets.
- Delivered a QR-code payment flow enabling customers to pay at the door via the courier app, expanding last-mile payment flexibility across markets.
- Proactively ran chaos experiments across tier-2, tier-3, and tier-4 production services ahead of high-traffic market launches, surfacing and eliminating failure modes before they reached customers.
- Drove observability and alerting improvements across delivery services to reduce MTTR and increase deployment confidence; took end-to-end ownership of medium- and long-term post-mortem action items to harden system resilience.

Senior Software Engineer — AdTech, New Verticals Tribe (May 2024 - Jul 2025)
Joined the new-verticals AdTech team at an early stage, contributing to the design, implementation, and infrastructure of an ads platform for groceries and pharmacy verticals — work that shaped the foundation before both AdTech teams were consolidated.
- Reduced AdRanker relevance component latency by 50% by tuning CPU request and limit parameters to eliminate throttling — a targeted intervention with immediate, measurable impact on the ads serving pipeline.
- Designed and implemented a feature cache to pre-process and store ML model inputs, enabling real-time product catalog ranking with very low latency.
- Developed a multi-category ranker service incorporating product popularity, user preferences, and promotions across different vendor categories.
- Implemented ML model versioning to support parallel model versions in production, and built a model monitoring solution to continuously measure and track model accuracy.
- Implemented an A/B testing framework with end-to-end tracking to support data-driven experimentation across the ads platform.
- Migrated infrastructure for several AdTech components to support a new Kubernetes version and Delivery Hero's internal global development platform.
- Technologies: Go · Kubernetes · GCP · Redis · Terraform · gRPC · OpenTelemetry · Grafana
Europe's leading online fashion and beauty platform, operating at massive scale across 200+ Kubernetes clusters.
Site Reliability Engineer (Dec 2021 - Apr 2024)
Worked across Zalando's core platform as part of the Embedded SRE programme — where SREs join product tribes to uplift reliability practices across entire engineering ecosystems — and later within the Gateway & Proxy team, owning edge infrastructure and platform tooling across Zalando's entire engineering organisation.
- Identified, designed, and drove a company-wide rate limiting and bot protection initiative for cart and checkout flows: built the mitigation strategy from scratch, developed statistical analysis tooling, authored documentation and training material, and reviewed a new leaky bucket rate limiting middleware — collectively cutting incoming bot traffic by over 50%, saving significant infrastructure costs and preventing load-induced outages.
- Conceived and shipped an internal risk register tool that gave engineering teams a direct line to surface reliability risks to senior leadership, creating cross-team accountability on post-mortem action items and meaningfully reducing toil across the department.
- Took ownership of distributed tracing and adaptive paging configurations for web experience and checkout teams, sharpening alert signal quality and eliminating a chronic source of false-positive incident pages.
- Contributed to Skipper, Zalando's open source reverse proxy in Go, and took an active role in rolling out Fabric Gateway — an API gateway enabling teams to configure routing, AuthN/AuthZ, rate limiting, and traffic shaping through OpenAPI specs and Kubernetes CRDs.
- Extended a Kubernetes metric adapter with external hostname-based metrics collection, unlocking richer Horizontal Pod Autoscaler signals beyond standard CPU/memory thresholds and giving teams more expressive autoscaling primitives.
- Overhauled the e2e test suite for Zalando's Kubernetes ingress controller, significantly improving reliability and coverage of a component sitting in the critical path of all cluster traffic.
- Facilitated post-incident reviews and served in 24/7 on-call rotations, using each incident as an opportunity to strengthen playbooks and drive cross-team learning.

Brazil's leading online real estate platform, enabling end-to-end rental and purchase transactions fully digitally. Site Reliability Engineer (May 2021 - Oct 2021)
- Designed and implemented a distributed, decoupled authorization and authentication layer for all back office applications, leveraging Open Policy Agent (OPA), Kubernetes instrumentation, and Kong proxy.
- Built Fluent Bit log pipelines to capture access logs across all company APIs, alongside a long-term log retention system to support data access auditing and compliance requirements.
- Technologies: Go · Kubernetes · Terraform · AWS · Shell Scripting
Healthtech specialized in corporate and hospital health care solutions.
Platform Engineer (Apr 2020 - May 2021) · Software Engineer (Sep 2019 - Apr 2020)
- Founding member of the Platform team as the company scaled — built core infrastructure from scratch including an ETL egress system, OAuth2/Envoy-based SSO, and a service mesh with distributed tracing and service IAM.
- Designed and built a microservice-based preventive healthcare platform serving physicians, hospitals, and patients, owning the full lifecycle from application development through deployment and infrastructure.
- Technologies: Go · Kubernetes · Istio · Envoy · Terraform · GCP · AWS · JavaScript · PostgreSQL
Software Engineer (Aug 2016 - Jun 2019) — Software outsourcing and R&D company focused on innovation projects across aerospace, energy, and consumer electronics.
- Worked on safety-critical avionic software under DO-178B — the international certification standard governing software in airborne systems — including formal verification of a communication protocol and building a test tool that reduced verification cycles from days to seconds.
- Built client-facing applications across multiple industries: a React/Django back office tool, a web application for smart grid monitoring, and a desktop application for digital audio processing.
