A payments business needed one platform to run initiation, authorization, capture, refunds, settlement and reconciliation across several payment providers. It could never double-charge a customer or lose an event.

• Designed independent microservices for initiation, authorization, transaction processing, refunds, settlement and reconciliation.
• Implemented the Saga pattern with compensating actions, and idempotent payment APIs so retries never cause a duplicate charge.
• Used the Outbox pattern, with event flows on EventBridge, SNS, SQS and Lambda: retries, backoff and dead-letter queues.
• Put each provider's gateway behind one internal contract, and built reconciliation that flags mismatches with automated recovery.
• Set up CI/CD and CloudWatch observability, and led design reviews and technical standards.

Website visitors with early questions had to wait for a sales rep. The business wanted them to get answers straight away on a live video call with an AI agent.

• Built the RAG pipeline end to end, including the chunking strategy and embeddings, so the agent answers from the company's own product content.
• Built the real-time video call experience on LiveKit.
• Made the agent show relevant product images and videos on screen as the conversation moves.

Surgery records arrived as PDFs, while compensation and physician schedules (QGenda) sat elsewhere. There was no single view of who covered which surgeries where.

• Built OCR extraction that turns uploaded surgery PDFs into structured data in PostgreSQL.
• Combined surgery, compensation and QGenda schedule data into reports, such as anesthesiologists per facility per month and facility-level summaries.
• Led the frontend team.

Teachers spend hours preparing lessons, question papers, presentations and assessments. The platform gives them AI tools built for those tasks, rather than a general chatbot.

• Led a 10-person team across frontend and backend.
• Wrote the prompts and guardrails behind the platform's generation tools.
• Built the RAG pipeline.

Buyers now ask ChatGPT, Claude and Gemini what to buy. This platform shows B2B companies how AI tools describe their brand, recommend their products and compare them with competitors.

• Led the full-stack team from the first commit, while coding in React.
• Built a HubSpot-integrated dashboard with form builders and insights.
• Delivered a CMS and reporting module for admins, guiding the frontend and API work.
• Ran requirement gathering directly with the founders.
