Leading backend architecture and LLM integration work in Python and FastAPI, with retrieval and agent-integration work built as proof-of-concept.

• →Leading backend architecture decisions across LLM integrations and FastAPI services, and owning technical direction for the backend team
• →Building a single orchestration layer over three agent platforms (Salesforce and Boomi over REST, and Azure AI Foundry over the DirectLine API), so the client talks to one interface regardless of which agent the user selects
• →Conducting code reviews, enforcing engineering standards, and guiding team members to build and adopt reusable backend components
• →Leading technical knowledge-sharing sessions and mentoring team members, raising overall engineering capability across the backend team
• →Participating in RFPs and client requirement gathering, providing technical solutions and effort estimates to support pre-sales and project scoping
• →Collaborating with cross-functional stakeholders to translate AI product requirements into maintainable backend solutions, consistently delivering on schedule

Built backend services and LLM-backed APIs in Python and FastAPI, including a document retrieval proof-of-concept on Azure.

• →Owned the Python processing pipeline in a rebuild of an insurance claim-comparison service that cut a 400-600 claim run (~5,000 claim lines) from 30-45 minutes to 10-15. Eliminated redundant claim fetches that were repeating 4-5 times per run, corrected data handling across worker threads, and moved PDF generation into separate web jobs.
• →Built a document RAG proof-of-concept on Azure (Azure AI Search + Azure OpenAI) over HIPAA-sensitive patient records, with Presidio-based PII redaction ahead of the model. Caught retrieval returning source documents across patient-record boundaries during testing, and enforced record isolation with metadata-scoped query filters. Discontinued before production on compliance grounds.
• →Developed retrieval-augmented generation pipelines as proof-of-concept, using semantic search over document sets to ground model responses
• →Integrated OpenAI and Azure OpenAI APIs into backend workflows, enabling LLM-powered automation pipelines
• →Built and maintained FastAPI services with a focus on reliability, performance, and maintainability

Led full-stack architecture and delivery for web platforms, driving performance work and scalable backend solutions.

• →Architected and maintained web platforms using React, Next.js, and Node.js, profiling and reworking the slow paths as they surfaced
• →Built robust RESTful APIs with NestJS enabling modular, maintainable backend services integrated with frontend applications
• →Defined and enforced code quality standards, testing practices, and CI/CD pipelines that improved team velocity
• →Conducted system analysis to identify bottlenecks and architectural improvements for more scalable, resilient solutions

Drove full-stack development and system architecture across web platforms, translating business requirements into scalable technical solutions.

• →Partnered with stakeholders to translate business requirements into detailed technical specifications, consistently delivering on schedule
• →Led architectural decisions across the stack, improving system scalability and long-term maintainability
• →Built and scaled React and Node.js applications with a focus on performance and reliability
• →Introduced testing and deployment standards that reduced release friction across the engineering team

Drove cross-platform mobile and web development, delivering polished user experiences across React Native, React.js, Android, and iOS.

• →Built and maintained shared React Native codebases, reducing time-to-market for cross-platform releases while preserving native-level performance
• →Analyzed and enhanced system functionalities across mobile and web surfaces, reducing defects and improving end-user experience
• →Applied platform-specific best practices from mobile to React.js projects, bridging the gap between the two surfaces
• →Operated effectively in a fully remote environment with strong async communication and consistent on-time delivery

Led end-to-end design, development, and delivery of mobile products across Android and iOS, managing a team and owning the full product lifecycle.

• →Directed cross-platform mobile development using React Native, Android (Java/Kotlin), and iOS (Swift), shipping products to production
• →Established code review processes and structured deployment pipelines, improving code quality and reducing release cycle time
• →Designed and shipped product features in close collaboration with product and design teams, improving user satisfaction and retention
• →Mentored junior engineers, fostering a culture of technical excellence, accountability, and continuous learning
• →Managed sprint planning and backlog prioritization across multiple concurrent mobile workstreams

Spearheaded Android development within an agile team, taking ownership of delivery from sprint planning to production release.

• →Collaborated directly with clients to establish program specifications and ensure clear, measurable deliverables
• →Resolved complex Android-specific challenges including performance bottlenecks, device compatibility, and architectural decisions
• →Facilitated Scrum ceremonies including sprint planning, daily standups, and retrospectives to keep the team aligned
• →Worked across the full delivery cycle from requirements through testing, QA, and production release

Led a mobile engineering team in the design, development, and delivery of Android and iOS applications, owning both technical direction and project outcomes.

• →Managed end-to-end delivery of mobile products across Android (Java) and iOS (Objective-C), ensuring quality and on-time releases
• →Conducted rigorous code reviews and established deployment processes that raised engineering standards and reduced post-release defects
• →Coordinated between engineering, design, and product stakeholders to align technical execution with business goals
• →Designed and shipped features with a strong focus on performance, maintainability, and user satisfaction

Contributed as a senior individual contributor on Android development, working across the full feature lifecycle from requirements to release.

• →Designed and developed Android applications in Java, applying best practices in architecture, performance, and code quality
• →Expanded into iOS (Objective-C) development, broadening platform coverage for the team
• →Partnered with product, design, and QA to define requirements, craft intuitive UIs, and deliver polished user experiences
• →Contributed to architecture discussions and helped define technical standards adopted across the mobile team

Delivered high-quality Android applications while leading bug triage and performance optimization efforts across the team's mobile products.

• →Owned core Android modules end-to-end from architecture through deployment
