Senior Software Engineer
I turn complex problems into software that works simply.
Backend engineering, thoughtful systems, and a habit of automating the repetitive stuff.
Business workflows you can explore, and the engineering behind them.
B2B operations
From signed customer to ready to launch.
A shared workspace for customers, reviewers, and account managers. Collect documents, resolve corrections, and activate an account when every requirement is approved.
Try thisRequest a correction, switch to the customer, and submit a revision.
Access control, Document versioning, Approval workflows
Commerce & payments
A return resolved. A refund accounted for.
Follow a partial return through support, warehouse inspection, and finance. Recover a payment whose response was lost while keeping the original refund intact.
Try thisExplore refund recovery and check the original payment status.
State machines, Transaction boundaries, Payment reconciliation
Event processing
Accepted is only the beginning.
An incoming webhook inbox that separates receipt from processing. Investigate failed attempts, handle duplicate or older events, and replay a failure with its history preserved.
Try thisSelect a failed event, repair its cause, and request a replay.
Event deduplication, Stale-event handling, Audited replay
Explore with fictional data, no sign-up needed. The hosted demos run in your browser; the source code includes the full backend implementations.
Try a delivery, interrupt a job, fix a mismatch, or drag the rollout slider.
A failed delivery is not a lost event
Same event. Another chance to arrive.
Signed webhook delivery with durable retries and a complete attempt history. The same saved event gets another chance when the receiving service recovers.
HMAC signatures, Retry backoff, Destination policies
Source code for Webhook RedriveProgress that outlives a worker
Keep completed work. Retry the unfinished activity.
A Go library that saves completed activities and recovers abandoned work. A replacement worker retries the unfinished activity using a stable effect key.
Worker leases, Crash recovery, Workflow compensation
Source code for Durable Task RunnerMake two systems agree again
Find the drift. Review it. Then repair it.
Compare records without changing either input. Review the differences, approve a bounded repair plan, and retain the evidence of every change.
Conflict resolution, Checkpointed syncs, Conditional repairs
Source code for Data ReconcilerRelease gradually, without reshuffling users
A wider release. The same users stay selected.
Stable percentage targeting expands a feature to a wider cohort. A local SDK evaluates cached configuration and uses explicit defaults when it becomes stale.
Deterministic targeting, Percentage rollouts, Offline evaluation
Source code for Feature Rollout ServiceInteractive illustrations of backend behavior. Everything runs in your browser.
A little about me
I’m a software engineer who enjoys figuring things out, building useful tools, and making complicated work a little simpler.
My experience on LinkedInI start with the problem. The goal is a useful result and a system people can understand and maintain.
I look for repetitive tasks that software can take care of, so people can focus on the parts that need their attention.
My focus is backend engineering and system design. I’m also exploring Go and building across the stack.
