Encrypted Inference Gateway

A privacy-preserving ML inference gateway with formal API contracts, encrypted request handling, and reproducible benchmark tooling.

Python FastAPI Pyfhel OpenAPI JSON GitHub Actions Jupyter Notebook

More details

Designed and implemented a privacy-preserving inference gateway for ML inference with formal JSON Schema and OpenAPI 3.1 contracts to ensure wire-level correctness, interoperability, and safe client-server workflows.
Built layered validation pipelines for CKKS-based encrypted inference, separating schema, envelope, and ciphertext checks to enforce safe deserialization and parameter compatibility before execution.
Developed a Pyfhel-based reference backend and Python client SDK for model discovery, local session creation, client-side encryption/serialization, inference submission, encrypted result retrieval, and local decryption.
Verified protocol behavior with end-to-end integration, ciphertext round-trip, and plaintext/encrypted agreement tests, then built reproducible benchmark tooling and GitHub Actions CI to quantify latency, throughput, payload growth, and output agreement while improving regression detection and release reliability.
Optimized the encrypted inference path by caching reusable CKKS contexts across requests, cutting mean encrypted infer time from ~311.9 ms to ~85.0 ms and improving end-to-end throughput by ~2.5x.

More details

Architected and built a full-stack mobile application that ingests, normalizes, and serves official legislative, policy, and representative data across multiple Canadian jurisdictions.
Designed a PostgreSQL/Supabase data layer with scheduled refresh jobs, serverless ingestion functions, public read views, and caching strategies for low-latency access to frequently updated public datasets.
Built server-driven push notification workflows for user-relevant civic changes, including device token registration, subscription synchronization, queued dispatch, and delivery test infrastructure.
Implemented email/password authentication, password reset, and backend-synced user state for preferences, saved content, and tracked civic activity.
Developed internal observability surfaces for refresh-status monitoring, data freshness validation, and backend debugging, improving confidence in scheduled ingestion and notification pipelines.
