Project history
Currently working on AI-powered products and full-stack capabilities for an online real estate platform serving more than 100 million unique users.
As a part of my job, I design and develop scalable web applications using TypeScript, React, Next.js, Node.js, Python, and FastAPI. I build frontend experiences, backend services, REST APIs, data-processing workflows, and integrations with large language models.
I develop AI features involving retrieval-augmented generation, semantic search, embeddings, prompt workflows, structured outputs, and automated evaluation. I also contribute to application architecture, authentication, performance optimization, testing, observability, Docker-based development, CI/CD, and AWS deployment.
I collaborate closely with product managers, designers, data specialists, QA engineers, and software engineers to transform complex real estate requirements into secure and reliable production solutions.
Worked in the CRM and Marketing team for a global B2B SaaS platform serving more than 70,000 businesses and 300,000 professionals.
As a part of my job, I developed scalable frontend and backend functionality for customer management, marketing automation, promotions, bulk operations, automated messages, appointment notifications, reviews, and partner-referral workflows.
I built reusable React and TypeScript components, developed Node.js services and APIs, worked with SQL data models, and implemented asynchronous workflows for communication and marketing operations. I also contributed to automated testing, code review, application monitoring, Docker environments, and continuous delivery.
Worked closely with product, design, QA, data, and engineering teams to turn complex operational requirements into reliable SaaS capabilities.
Worked on Wheely’s B2B platform and related internal products for premium mobility operations.
As a part of my job, I developed customer-facing and internal web applications, backend services, API integrations, company onboarding, authentication, account management, and operational workflows. I also helped establish reusable frontend components and shared engineering standards across the platform.
Worked with a cross-functional team of more than 20 people to launch a new version of the B2B portal, contributing to a 78% increase in active companies and a 50% increase in revenue.
I contributed to system architecture, code reviews, testing, release automation, production monitoring, and cloud deployment while collaborating with business leaders, product managers, analysts, designers, and engineers.
