01 — Experience
Six companies. Six definitions of “production.”
A startup platform team, fitness SaaS at scale, Fortune 50 retail, fintech, big tech, and a full-stack start in Kathmandu — each one sharpened a different engineering muscle.
ACE Virtual Shooting
Tech lead for the platform-services team — authentication, identity, shared infrastructure, and the product’s Gen AI features. Primary on-call for platform services.
- Drove the end-to-end migration of the customer-facing platform from Bubble.io to NestJS for 60K+ users — architecture, execution, and rollout.
- Designed and hardened serverless magic-link authentication on AWS Lambda, Cognito, and DynamoDB, spanning web, VR, and mobile deep-link flows.
- Built Gen AI features end-to-end with Anthropic Claude: customer-facing LLM capabilities, RAG pipelines over internal data, and AI agents powered by custom MCP servers.
- Built auth-error observability from scratch (Terraform + DynamoDB + Grafana), then used it to detect and mitigate a live WAF attack — hardening WAF rules and retry logic in response.
- Owned the AWS estate as Terraform code — Lambda, DynamoDB, RDS PostgreSQL, Cognito, S3, WAF, SES — with Grafana/Prometheus observability and GitHub Actions CI/CD.

ABC Fitness
Java/Spring Boot microservices at scale for a platform processing memberships and billing for thousands of gyms.
- Built secure RESTful APIs with JWT and AWS Cognito; deployed Spring Boot services on Kubernetes (EKS) with GitHub Actions CI/CD.
- Ran high-throughput workloads on RabbitMQ messaging and Redis caching; tuned schemas, indexes, and caching to harden APIs.
- Carried on-call and led production incident response across distributed services; upgraded legacy Spring Boot services and remediated CVEs.

The Home Depot
Full-stack work on the appliance e-commerce experience — React components in front, Java services and GraphQL behind.
- Built reusable React components with Redux and SCSS to internal design standards for a high-traffic retail surface.
- Developed Java/Spring Boot REST APIs and integrated GraphQL services on GCP for product data.
- Investigated and resolved traffic spikes and performance regressions across staging, beta, and production during peak retail loads.

Fiserv
Internal financial-data applications and a platform modernization — from legacy JBoss to React, Spring Boot, and OpenShift.
- Developed Node.js/Express and React applications used daily for financial data processing and calculations.
- Migrated legacy applications to React + Java/Spring Boot and rebuilt deployment pipelines from JBoss to OpenShift on AWS.
- Established CI/CD automation on Azure DevOps, built a reusable core-UI React library, and mentored junior developers.

Apple
Internal engineering tools and services supporting product programs — with Apple’s bar for polish, privacy, and performance.
- Shipped React + TypeScript interfaces and Node.js (Express) services used daily by engineering and operations teams.
- Worked in a privacy-first culture where data handling, accessibility, and detail-level UX review were table stakes.

Ambit Techno
Where it started: full-stack delivery across React, Angular, and Spring + Hibernate.
- Built full-stack web applications with React, Angular, and JSP frontends over Spring/Hibernate REST APIs.
- Modernized legacy codebases to current standards — cutting operating costs by ~35% — and wrote UNIX shell scripts for scheduled batch jobs.

04 — Approach
How I work.
Enterprise discipline
Six companies taught me the same lesson six ways: production is the only environment that matters. I write code that survives compliance review, on-call, and the engineer who inherits it.
Startup velocity
On a startup platform team, shipping this week beats perfect next quarter. I scope ruthlessly, choose boring technology, and keep the product working while the platform matures.
Full-stack ownership
I don’t hand off at the API boundary. Schema, service, pipeline, interface, dashboard — owning the whole slice is how I keep systems coherent and postmortems short.
AI-augmented, human-reviewed
Agentic tools multiply output, not judgment. I build LLM products for users and use Claude Code daily myself — and keep design decisions, reviews, and merges firmly human.
