Dear Hiring Manager,

I've rarely had the background on paper for the roles I've taken. What I do bring is a habit of walking into unfamiliar systems and quickly becoming someone the team relies on. Finding what's actually broken, fixing it, and leaving things in better shape than I found them.

My current role is senior technical support on an enterprise platform. Client escalations end-to-end, plus the scripts and automation I write around the role to cut down on repeat work. Before that, platform and microservice work on a regulated core banking product.

I pick things up fast, work well under pressure, and prefer fixing the cause over closing the ticket. Happy to talk if that sounds useful.

Yours sincerely,
Alex Susanu

Support and platform engineer. Work spans enterprise technical support, DevOps, and software development — and I move across all three without handing off.

Experience

Support Engineer · Clinisys — LIMS Platform
Jul 2025 – Present
Senior technical support role on an Oracle-backed Laboratory Information Management System serving global clinical and scientific clients across the UK, US, and APAC. Covers client-facing escalations alongside internal tooling and engineering work that comes out of them.
Client-facing
  • Primary technical contact across a global client portfolio spanning multiple regulated laboratory environments.
  • Took complex multi-day escalations across Oracle, IIS, Telerik, and C# layers to full resolution independently.
  • Identified and fixed systemic root causes across recurring failure patterns, reducing repeat ticket volume.
  • Maintained relationships with enterprise clients in regulated industries where downtime carries direct operational risk.
Engineering & internal tooling
  • Built PowerShell automation for IIS log collection and parsing, replacing a manual, error-prone investigation process.
  • Developed Chrome extensions to fill functional gaps in the native LIMS platform; adopted across the support team.
  • Wrote XML parsers automating audit-trail extraction from LIMS exports for compliance and investigation workflows.
  • Co-authored Oracle PL/SQL procedures covering report generation, custom functions, and client-specific logic.
  • Built Oracle SQL diagnostic scripts isolating database-layer issues ahead of DBA escalation, shortening resolution time.
Associate Software Engineer · 10x Banking — Core Banking Platform
Nov 2021 – Jul 2024
Platform-side role on a regulated core banking product. Started supporting feature teams across the CI/CD and Kubernetes stack, then moved into the Data Analytics team building and maintaining internal microservices. Worked across Java / Spring Boot, Python, Kubernetes, Helm, Docker, Jenkins, and AWS in a production environment with real regulatory stakes.
Platform support for feature teams
  • Internal support for feature engineering teams across the platform stack — Kubernetes, Helm, Docker, Jenkins, AWS.
  • Debugged Kubernetes workload failures and helped feature teams unblock deployments and pipeline issues.
  • Maintained Jenkins CI/CD pipelines and Docker-based test environments used across the product.
  • First-line response for production incidents on live banking services, monitored via New Relic and CloudWatch.
Data Analytics — microservice development & client support
  • Contributed to upgrades and maintenance of existing Java / Spring Boot microservices inside the Data Analytics team.
  • Built an internal-facing Java / Spring Boot microservice from scratch to automate a recurring data workflow, reducing manual effort for the team.
  • Handled support tickets from clients consuming analytics services — triaged, reproduced, escalated, and followed fixes through to release.
  • Wrote Python and Bash tooling around the service layer to cut down on manual data-engineering overhead.
Freelance Technical Consultant · Independent (Remote)
2018 – 2024
Custom technical solutions for small and medium businesses across automation, integrations, and internal tooling.
  • Automated reporting workflows replacing hours of weekly manual processing, typically recovering project cost within the first month.
  • Connected incompatible business systems via custom REST API integrations, eliminating manual data transfer.
  • Built Chrome extensions adding missing functionality to tools clients already relied on.
  • Delivered Python and Bash automation across invoicing, data entry, and operational workflows.
  • Built Spring Boot APIs and Bash monitoring scripts for clients without in-house engineering.

Portfolio

I keep a public site (alexsusanu.com) of the tools I build for my own support work, write-ups of problems I've debugged, and notes as I study toward cloud-native and security certs. Built to show, not tell.
