• Conducted code reviews on all incoming PRs, maintaining quality and consistency across the codebase;
• Provided pair programming support to unblock engineers on complex implementation tasks.

A B2B SaaS platform for the multifamily rental industry that provides airport-grade identity verification, income and employment qualification, and lease approval in a single workflow. The platform integrates biometric identity checks, real-time income verification, and a Verified Renter Network to help property operators reduce fraud, accelerate leasing decisions, and improve portfolio performance.

• Architected and built the full platform from scratch using Django Ninja, React/Vite, TypeScript, PostgreSQL, and Docker;
• Designed and implemented 140+ REST API endpoints across 6 Django apps, organized with a service-layer architecture;
• Built an income review queue system with priority scoring, significantly reducing application processing time;
• Implemented a custom granular RBAC permission system with role-based access control, permission decorators, and audit logging;
• Engineered a shared database architecture mapping 35+ unmanaged Django models to a centralized Supabase instance;
• Delivered production-ready dashboards with queue analytics, trend visualization, aging analysis, and assignment workflow tracking;
• Consolidated 9 external third-party services into one unified internal application, reducing operational overhead across the team;
• Led the engineering team and coordinated delivery milestones with the product manager.

A decentralized residential energy management platform that enables homeowners to monitor, control, and monetize solar panels and battery storage assets through a unified web and mobile interface. The platform integrates with utility providers, payment processors, and document-signing services to automate onboarding and payout workflows, and serves both homeowners and solar installers through dedicated portals.

• Developed the backend from scratch, architecting scalable REST and GraphQL APIs integrating Stripe (payments & identity), Twilio (OTP), PandaDoc (document signing), and Arcadia (utilities);
• Engineered an automated image validation system using Google Cloud Vision, Vertex AI, and OCR — reducing manual review time by an estimated 80% and preventing fraudulent submissions via geofencing, reverse image search, and appliance detection;
• Designed and optimized GraphQL queries and mutations for the native iOS app, enabling real-time energy monitoring and minimizing data payload;
• Built custom Django-based portals for solar installers and customers, streamlining job creation and onboarding workflows
• Developed React/Vite and Next.js frontends connected to the backend APIs;
• Trained a custom Vertex AI model for the solar equipment image validation feature.

A B2B marketplace platform for the property and construction industry, connecting property vendors with project teams to facilitate procurement partnerships and contractor coordination.

• Led end-to-end development from concept to launch as a founding engineer, architecting the backend with Django/PostgreSQL and the frontend with Next.js/TypeScript;
• Directed and mentored a distributed team of 5–8 engineers across time zones, maintaining consistent delivery of product milestones;
• Integrated Stripe Connect for secure, compliant financial transactions across all platform users;
• Orchestrated a backend migration from Django 3 to Django 4.2, reducing infrastructure costs and improving stability;
• Led the frontend migration from Vue 2 to Next.js/TypeScript, significantly improving performance and developer experience;
• Established engineering foundations — documentation, coding standards, and CLI tooling — reducing new engineer ramp-up time by 50%.
