Endtoend.Nohandoffs.

Six and a half years shipping end-to-end. I take features from data model to deployed UI — designing the schema, writing the services, building the screens, running the deploys. Backend-deep by training, full-stack by delivery. Built across telecom, fintech, govtech and edtech — every system shipped with measurable lift.

I take features all the way through.

  • 01I ship end-to-end. Schema to surface, service to screen — no handoff costs, no blocked tickets, no waiting on the other team.
  • 02Backend is my depth — Java/Spring Boot, Node/NestJS, microservices, AWS — but I write the React and Angular too. The same engineer ships the API and the form that calls it.
  • 03I have worked across four verticals — telecom, fintech, govtech, edtech — because the discipline travels: model the domain, draw clean boundaries, instrument what matters, ship measurable lift.
  • 04Every system I have owned shipped with a number attached: 30% faster APIs, 70% less manual work, 35+ enterprise integrations. If it does not move a metric, I do not ship it.

02Capability · operating envelope

The stack I reach for, and why.

A capability map, not a skill checklist. Grouped by what they do, not by where they sit on a resume.

Backend & APIs

18

The core. Java/Spring Boot for enterprise weight; Node/NestJS for velocity.

  • Java
  • Spring Boot
  • Spring Cloud
  • Spring AOP
  • Microservices
  • Node.js
  • Nest JS
  • Express.js
  • REST APIs
  • JWT
  • OAuth2.0
  • Socket.io
  • Maven
  • NPM
  • Performance Optimization
  • Circuit Breaker
  • Retry Patterns
  • Rate Limiting

Architecture

07

Patterns I reach for when systems get real — circuit breakers, idempotency, caches.

  • Microservices Architecture
  • API Security
  • OOP
  • DSA Fundamentals
  • ETL & Data Migration
  • Distributed Systems
  • Caching Strategies

Cloud & DevOps

08

AWS-native deploys, CI/CD discipline, observability before incidents.

  • AWS (S3, EC2, App runner, Code Build, Code Pipeline, IAM, ECR, Lambda, Secrets Manager, RDS, Cloud Watch)
  • Docker
  • Jenkins
  • SonarQube
  • Git/GitHub/GitLab
  • Grafana
  • Shell Scripting
  • CI/CD

Data

06

Relational by default, document where it earns its place, Redis when latency demands.

  • PostgreSQL
  • MySQL
  • MongoDB
  • Stored Procedures
  • Triggers
  • Redis

Frontend

05

Where users meet the system. React for product UX, Angular for enterprise, React Native for mobile.

  • JavaScript (ES6)
  • TypeScript
  • React.js
  • Angular (10+)
  • React Native

AI workflows

08

Force-multiplier, not job title. Cursor + Claude + Gemini compress the loop.

  • GitHub Copilot
  • Gemini
  • Claude
  • Cursor
  • AI assisted development
  • Prompt Engineering
  • Agentic Development workflows
  • Antigravity
03Selected work · 2019 → present

Four verticals. One discipline.

Same patterns, different domains: model the system, draw clean boundaries, instrument what matters, ship measurable lift. Each engagement is one deliberate study.

You don't ship by accident.

If you're hiring a senior full-stack engineer, looking for someone who can own a feature end-to-end, or building a product that needs both depth and delivery — I'd like to hear about it.
