About

Senior Software Engineer with 7+ years shipping cloud-native apps, scalable backends, real-time systems, and full-stack products. I optimize for maintainable architecture, clear performance characteristics, and delivery that matches what stakeholders actually need.

Day-to-day AI engineering: Cursor-style assisted development, multi-model LLM workflows per task, and agent-style support for exploration and review—without lowering the production bar.

What I deliver

Systems and software engineering first; AI where it creates clear product value.

Build and scale

Production-grade backends, APIs, real-time systems, and cloud-native architectures on GCP and related stacks. Reliability, performance, and cost-aware operations for products that must hold up in the real world.

AI and intelligent features

LLM integration, intelligent workflows, and automation inside real products—not slide decks. Pragmatic patterns for prompts, evaluation, and guardrails, aligned with user trust and business constraints.

Lead and deliver

Hands-on technical leadership: architecture decisions, mentoring, stakeholder alignment, and predictable delivery across enterprise and startup contexts — while remaining deep in implementation and production systems.

AI in production standards

Practical rules I follow to ship AI features that are measurable, reliable, and safe under real usage.

Evaluation before rollout

I define quality checks up front (task accuracy, failure patterns, and acceptance thresholds) so AI features are shipped against evidence, not demos.

Guardrails and fallback paths

Every AI flow has constraints (input/output checks, policy boundaries, and fallback behavior) to keep user experience stable when models drift or fail.

Observability and traceability

Prompt versions, model choices, and key outcomes are tracked to make regressions visible and speed up incident debugging.

Cost and latency discipline

I tune model usage, caching, and orchestration patterns for predictable response time and cloud cost under real traffic.

Human review where risk is high

For sensitive decisions, AI assists but does not finalize alone. Human-in-the-loop review is explicit in the workflow.

Incremental release strategy

I ship in stages (pilot, monitor, expand) with rollback plans, so AI capabilities improve safely in production.
