Selected engineering work.

Internal deployment platform replacing manual SSH-based releases for a multi-environment SaaS.

Problem

Releases required a senior engineer on a call and took 90 minutes on average. Rollbacks were destructive and rare.

Solution

Designed a Git-driven deployment pipeline with environment promotion gates, immutable artifacts, and one-command rollback. Documented the operator runbook end-to-end.

Outcome

Average deploy time reduced from 90 minutes to under 6. Junior engineers shipping to production within their first week.

Event ingestion and aggregation system for a high-volume consumer product.

Problem

Product analytics relied on a daily batch job. Decisions on shipped features lagged 24–48 hours.

Solution

Built a streaming pipeline that ingests events through a managed queue, aggregates in-flight, and surfaces dashboards updated every 30 seconds.

Outcome

Time-to-insight cut from 36 hours to under a minute. Three product experiments shipped in the time the old pipeline produced one report.

Tearing out a noisy monitoring stack and replacing it with a small set of signals that mattered.

Problem

The on-call rotation was burning out. 80% of pages were false positives; real incidents were lost in noise.

Solution

Redefined SLOs based on actual customer impact, rebuilt dashboards around four signals, and pruned 60% of legacy alerts.

Outcome

False-positive page rate dropped below 10%. On-call satisfaction measurably improved in the next survey cycle.

AI-assisted extraction service turning scanned operational documents into structured data.

Problem

An operations team manually keyed information from PDFs into a CRM. The work was error-prone and consumed an entire role.

Solution

Built an extraction service combining OCR with a constrained LLM step, with a human review queue for low-confidence outputs.

Outcome

Manual entry time fell by 85%. The reclaimed role was redirected to higher-leverage customer work.

Replacing six spreadsheets with a typed, observable system of record for an operations team.

Problem

The operations team manually reconciled six spreadsheets every morning. The reconciliation was the bottleneck; errors compounded weekly.

Solution

Modeled the workflow as a typed state machine, built a thin internal UI, and connected each step to an audit log. The spreadsheets became read-only exports.

Outcome

Reconciliation dropped from 2 hours daily to a 5-minute end-of-day verification. Zero compounding errors in six months.

• PostgreSQL
• Nuxt
• TypeScript

Pre-launch security review and remediation for an early-stage fintech.

Problem

Launch was blocked on a compliance review the team did not know how to pass. The codebase had no centralized secrets management and inconsistent input validation.

Solution

Audited the surface area against OWASP Top 10, introduced a secrets vault, standardized validation at the edge, and documented the threat model.

Outcome

Compliance review cleared on first submission. Time-to-launch unblocked.
