Software Developer
DarioHealth
- Built cross-region Apache Kafka event pipeline spanning 6 AWS regions with clusters centralized in us-east-1; developed an internal Python package for Kafka producers and consumers and implemented Celery workers to publish events asynchronously; researched and defined IAM and VPC peering requirements for secure cross-region MSK access.
- Executed eligibility file fallout reporting pipeline for million-record datasets, generating structured error reports with column-level validation, standardized error codes, and descriptive messages for invalid records.
- Migrated Dario Eligibility system from legacy infrastructure and built a reusable, CMS-controlled user-blocking modal supporting dynamic ineligibility messages via Flask-Admin.
- Leading Hygraph CMS unification across multiple products into a single project, eliminating redundant content management workflows and enabling clinical and content teams to manage all products from one platform.
- Led accessibility overhaul of DarioMind application, resolving 100+ WCAG 2.1 violations—added NVDA screen-reader support, improved voice-control accessibility, and resolved high-zoom reflow issues—resulting in VPAT certification and fulfilling Amazon’s renewal requirements.
Associate Software Developer
DarioHealth
- Supported Node.js v16 to v20 upgrade across multiple serverless microservices, ensuring backward compatibility and zero-downtime deployment to production.
- Developed and executed data-migration scripts to transition legacy user-flow datasets to the new system architecture, maintaining data integrity throughout.
- Resolved 100+ Ox-Security flagged vulnerabilities across 5 microservices (20 per service), hardening security posture and optimizing backend performance across the platform.
Projects
FlowGuard — Distributed API Gateway & Rate Limiter
- Built an API gateway in Flask that proxies requests and enforces configurable rate limits using three algorithms: fixed window, sliding window log, and token bucket— with documented tradeoffs for each.
- Stored rate limit rules in PostgreSQL with Redis caching; implemented rule precedence (specific IP + endpoint beats wildcard) and hot-reload on rule updates without gateway restart.
- Load tested with Locust (20 concurrent users) — 429 responses return in ~11ms by short-circuiting at the Redis layer, achieving 91% block rate on rate-limited endpoints.
AI-Powered Personal Finance Tracker
- Integrated AI function calling via Google Gemini API and Model Context Protocol (MCP) server for structured expense operations, enabling natural language transaction management.
- Designed a Flask-based Feature Flag microservice using SQLAlchemy and PostgreSQL to gate AI feature rollout at the user level, enabling safe A/B experimentation.
- Containerized entire stack (React, Express.js, Flask, MongoDB, PostgreSQL) with Docker and Docker Compose, enabling one-command deployment with isolated networks and persistent volumes.
