Architect and hands-on lead to design and build domain-driven Node.js/TypeScript microservices. Own greenfield systems, APIs, CI/CD, observability, and production readiness. Lead incident triage and RCAs, mentor engineers, drive standards, and collaborate cross-team to deliver scalable, secure customer-facing digital experiences.

Build and maintain a scalable design system: reusable, accessible UI components and tokens; translate Figma/Sketch specs into production code; enforce design standards, accessibility (WCAG/ARIA), versioning, and improve developer experience through tooling and documentation while collaborating with designers, product managers, and engineers.

Lead end-to-end UX design: create wireframes, prototypes and mock-ups (Figma); conduct user research and usability testing; use data and AI tools to inform decisions; present to stakeholders; facilitate workshops; integrate design systems into engineering workflows and ensure smooth handoffs.

Lead and operate CI/CD pipelines and cloud infrastructure using IaC (Terraform/ARM/CloudFormation) across Azure/AWS/GCP. Automate provisioning, monitoring, and scaling; implement logging and alerting (App Insights, Splunk, Datadog, Prometheus); enforce security and compliance; partner with dev/QA/security/release teams; troubleshoot production incidents and perform root cause analysis.

Develop, test, debug, and maintain software applications and tools using Agile methodologies. Participate in design, architecture, and build phases; evaluate compatibility with existing communications hardware/software; resolve problems and roadblocks; collaborate with internal and external peers and managers; work as both individual contributor and team member to deliver high-quality deliverables.

Design, develop, and maintain scalable Java/Spring Boot backend and Angular frontend applications. Build microservices, RESTful APIs, event-driven solutions with Kafka, implement fault tolerance (Hystrix/circuit breakers), observability (SLI/SLO), and deploy on Kubernetes/AWS. Collaborate with cross-functional teams, mentor junior developers, and ensure reliability and performance.

Lead QA Automation for agentic AI products by designing eval pipelines, golden datasets, and automated tests for tool-use, hallucination detection, latency/token monitoring, and regression across models and prompts. Integrate performance testing into CI/CD and collaborate with AI engineers to convert requirements into measurable automated evaluations.

Build and maintain Java Spring Boot microservices and serverless functions. Design RESTful APIs, integrate with Vue.js front-end, write unit tests (JUnit/Mockito), deploy containerized apps to AWS EKS and Lambda, and maintain CI/CD pipelines for reliable releases.

Design, develop, and maintain scalable full-stack web applications using React, NestJS, TypeScript, and Node.js on GCP. Architect REST APIs and microservices, model NoSQL data with Firebase/Firestore, implement CI/CD and deployment automation, ensure security and performance, conduct code reviews, troubleshoot production, and collaborate on technical design.

Lead design, build, and maintain scalable ML infrastructure and CI/CD pipelines. Collaborate with data science and operations teams to deploy containerized models (Docker/Kubernetes), optimize cloud resource usage and security, apply IaC (Terraform), and mentor junior engineers.
