Senior backend engineer with 10+ years building Java, Spring Boot, and Kubernetes microservices for telecom and finance.
Data Engineer · Toronto
Hired to modernize data-intensive paths on AKS. Owned the upload pipeline and source-onboarding experience end to end — from batch windows that stalled operators to config-driven loaders and latency outcomes a hiring manager can probe in an interview.
OWNED
End-to-end ownership of the file-upload path and API source onboarding for platform consumers.
BEFORE → AFTER
Multi-minute batch upload windows and week-scale API source onboarding → 60% ↓ upload latency and 40% ↓ feed onboarding via a config-driven API Source Loader, with OTel → Datadog so regressions surface in ops.
TALKING POINT
"How did you keep the loader config-driven without turning every new feed into a deploy?"

Software Developer · Toronto
Built a Spring Boot recovery console operators actually use: detect inconsistencies, emit actionable reports, and remediate without opening an engineering ticket for every incident — cutting operational overhead instead of adding queue noise.
OWNED
Designed and delivered ART for ops inconsistency detection and remediation workflows.
BEFORE → AFTER
Manual chase of inconsistent billing/ops data → 25% ↓ operational overhead with a detect → report → remediate loop.
TALKING POINT
"What's the difference between a recovery tool operators trust and one they ignore?"

Systems practice (self-hosted)
Long-running self-hosted platform used to rehearse the same habits as production backends: named blast-radius boundaries, ingress + identity at the edge, and observability you actually look at. The Selected Builds card shows the fleet topology; this study is about the operating posture.
OWNED
Sole operator — design, secure, and run the fleet end to end.
BEFORE → AFTER
Single-box ad-hoc containers → named hosts, plane separation (edge / apps / data), and fleet monitoring you can query when something breaks.
TALKING POINT
"What did running your own edge teach you that a cloud tutorial did not?"

Self-hosted platform
Six-host fleet with Traefik/CrowdSec/Authelia at the edge, app nodes, media as a workload line, and Beszel/Dozzle/Homarr across the board — not "I run Plex."
OWNED
Sole operator of a six-host edge / apps / data fleet with shared monitoring.
BEFORE → AFTER
Ad-hoc containers on one box → named hosts, ingress + authz, observability, and clear blast-radius boundaries.
TALKING POINT
"Walk me through how you'd isolate a compromised edge node without taking the media or app planes down."

Owned the path from slow batch uploads and week-long source onboarding to config-driven loaders and measurable latency wins — Spring on AKS, with observability wired for real ops.
OWNED
End-to-end ownership of upload path + source onboarding UX for platform consumers.
BEFORE → AFTER
Uploads stuck in long batch windows; new API sources took weeks to land → 60% ↓ upload latency, 40% ↓ feed onboarding time via config-driven API Source Loader.

Built a Spring Boot recovery console that detects inconsistencies, produces actionable reports, and supports remediation — cutting operational overhead instead of adding another ticket queue.

Full-stack product surfaces — secondary to platform work above.
Multi-tenant admin dashboard for managing products, orders, and analytics. Built with Next.js, integrated with Stripe for payments and Clerk for authentication.
Modern e-commerce storefront with product catalog, shopping cart, and checkout flow. Headless CMS architecture consuming admin API.
In the ThreadLocal leak post, ScopedValue was the third fix — two paragraphs and a filter snippet. This is the full treatment, because JDK 25 changed its status: after an incubator round in JDK 20 and previews in JDK 21–24, JEP 506 made java.lang.ScopedValue final in JDK 25. No …
Vercel's developer experience is genuinely excellent — push to Git, get a URL, previews for every pull request. The bill is the problem: per-seat pricing plus usage, and it scales with your success. Dokploy is the self-hosted answer that's been eating that market: an …
Google "Spring Boot JWT tutorial" and the top results still hand you the 2019 recipe: a custom OncePerRequestFilter that parses the Authorization header by hand, a third-party JWT library, a UserDetailsService, and five config classes of glue. It works — the way a …
Every Spring codebase has its own API versioning story, and they're all slightly embarrassing: /v1 and /v2 prefixes baked into paths, a custom header parsed by hand in an interceptor, or two parallel controller classes that drift out of sync. Spring Framework 7 — the …
