Computer Science student at Cal State San Marcos, working across cloud infrastructure, backend applications, computer vision, and GPU inference. I like owning things end to end — application code, the infrastructure under it, deployment, testing, and keeping it running. Open to software engineering internships and part-time development work.

Paste a TCGplayer link, get a sticker price for every condition — Near Mint through Damaged — as whole dollars. The figure is what the card actually costs a buyer online including shipping, so a customer walking out with it today is not paying more than they would waiting a week for the mail. Sole engineer across product, infrastructure and testing.

The pricing engine is written twice on purpose — a Python reference and the TypeScript port that actually runs — with golden tests asserting the port reproduces the reference byte for byte from shared fixtures. 359 automated tests across both.

Built and deployed, not yet in service: auth and billing are wired against Clerk and Stripe in test mode rather than running in production.

Took AWS's multi-provider GenAI gateway from an empty repository to a live, TLS-secured production endpoint — ~120 AWS resources provisioned with Terraform, and ownership of the deployment lifecycle after it was running. LiteLLM fronts Amazon Bedrock behind one OpenAI-compatible endpoint; VPC, ECS Fargate, ALB, RDS, ElastiCache, WAF, Secrets Manager and Bedrock VPC endpoints, with a remote S3 state backend, Route 53 + ACM, least-privilege IAM and per-key cost observability. Bedrock Guardrails plus a Presidio PII-masking sidecar — where I traced a masking defect to a dependency version and fixed it with a controlled upgrade and regression testing.

Scope and credit: the architecture is AWS's own reference design, not mine. My work was the deployment and the operation of it — a real production task set by Cisco professionals at Riffyx Labs.

A closed loop against real hardware: capture an Android device's screen over ADB, locate the target with a fine-tuned YOLO11 detector, decide, and actuate a gesture back to the phone. A self-supervised flywheel has the running agent label its own training data (5,400+ frames), corrected through a human review UI and fed back through a train → validation-gate → ship pipeline with ONNX export. Per-frame capture taken from ~600 ms to ~1.3 ms, each tap from ~200 ms to ~20 ms, with multi-device orchestration and self-healing recovery. 127 automated tests.

_{Source is private — happy to walk through the architecture and the training pipeline.}

Written from scratch in Java 21 rather than wrapped around an existing engine. The storage layer is the same shape as LevelDB and RocksDB — write-ahead log, in-memory memtable, sorted on-disk SSTables, leveled compaction, bloom filters — behind a TCP server speaking Redis's RESP protocol, so redis-cli, redis-py and Jedis connect unmodified. TLS, multi-user auth, pub/sub and snapshots. 203 automated tests, ~5,200 lines.

7 pull requests merged into repositories totalling 42,000+ stars. Fixes in codebases I do not maintain — found by reading unfamiliar code, diagnosed by measurement, and defended in review.

_{Two worth reading in full: rakazo #322, where the reporter wrote "I cannot explain the root cause" and I narrowed it by elimination; and trueforge #464, where a reviewer questioned whether an abort was needed and I measured it rather than argued it — Promise.race frees the caller but leaves the socket open.}

Built a card-pricing product end to end as sole engineer — product, infrastructure and testing. Deployed and live at landedcards.com; auth and billing are wired but not yet running in production.

Riffyx Labs — Engineering Mentee · 2025 – 2026

Deployed and operated a multi-provider GenAI gateway on AWS, provisioning ~120 resources with Terraform across ECS Fargate, RDS, ALB, WAF and Bedrock, with Guardrails and PII masking. Given a real production task by Cisco professionals and completed it end to end.
