Kolya – Python, React, Django

From idea to email in 30 seconds. Inspired by the best in SaaS.

• Built a B2B email campaign platform (Python/FastAPI, React/Next.js) with a custom campaign editor, multi-tenant REST APIs, AI personalization features, and webhook integrations.
• Implemented structured LLM generation (system prompts + schema-driven outputs) to produce HTML email variants across hundreds of use cases, with validation and fallback logic to prevent broken templates and formatting regressions.
• Deployed and operated a production AWS platform (EKS/Fargate/EC2/Lambda/S3) with Terraform, Docker, and GitHub Actions CI/CD, supporting scaling, reliability, and Stripe billing.

Dispensed Australia is a patient-first platform committed to providing trusted, personalised healthcare support that’s easy to access and understand.

• Owned the backend architecture (Node.js/TypeScript, Supabase, PostgreSQL, Edge Functions): event-driven workflows for patient onboarding, prescription polling, billing, and PDF document generation.
• Implemented asynchronous processing patterns (scheduled polling, idempotency, retries with fallbacks, workflow state tracking) to keep clinical and billing flows reliable under failures and high traffic.
• Built the mobile app (React Native/Expo) covering onboarding, prescriptions, payments, document delivery, and user communications. Integrated external systems: Typeform, Semble (clinical), Chargebee (billing), and Resend (email).

United States high-traffic e-commerce platform.

• Drove design system work, UI/UX redesign, and new customer-facing services (Node.js, TypeScript, React, Storybook).
• Migrated legacy services to a Kafka-driven architecture, increasing system resilience and scalability to handle 1M+ daily events.
• Owned search and product discovery improvements using Algolia (indexing, relevance tuning, facets), supporting catalog flows.
• Set up product analytics instrumentation (events, funnels, dashboards) and strengthened reliability and observability with Sentry monitoring and performance tracing.

An innovative AI-driven design-to-code plugin.

• Built and scaled core backend APIs (Python, Flask, MongoDB, Redis, Docker) to support high-volume AI workloads.
• Owned the AI code generation layer: maintained a library of system prompts and personalization rules, and built a Python engine that converts Figma nodes into an intermediate AST for consistent, structured output.
• Delivered CI/CD and release automation (Travis CI), E2E automation (Cypress, Ghost Inspector), and production monitoring (Sentry).

A significant media platform with over 20 million monthly users.

• Developed serverless microservices in Python/Flask and AWS Lambda, integrating with Kafka, SQS, and REST APIs for content publishing workflows.
• Built frontend UIs in React and TypeScript, integrated with backend APIs, and deployed with CI/CD automation.

A UK-based financial services platform, encompassing multiple initiatives including a crypto solution, a finance management system, and an investment platform

• Developed backend services in Python (Django, Flask) and modernized legacy systems to Python 3, improving maintainability and performance.
• Designed RESTful APIs and managed relational databases with PostgreSQL.
• Collaborated with frontend teams, integrating APIs into modern JavaScript frameworks.
