About

Engineering software that holds up under pressure

A snapshot of how I think about building backend systems, APIs, and data-driven products.

Software Engineer with internship experience building scalable backend applications, REST APIs, AI-powered solutions, and analytics dashboards using Java, Spring Boot, Python, FastAPI, Node.js, SQL, PostgreSQL, and Power BI. Experienced in performance optimization, database design, API development, distributed systems, and software testing. Passionate about solving real-world engineering problems through clean, maintainable, and data-driven software solutions.

Backend Development

Designing layered, maintainable services with Spring Boot, FastAPI, and NestJS, following clean architecture and separation of concerns.

Distributed Systems

Building event-driven, real-time systems using Redis Pub/Sub, message-based communication, and resilient data flows.

REST & GraphQL APIs

Shipping well-documented, production-grade APIs with Swagger/OpenAPI, GraphQL schemas, and robust validation layers.

Performance Optimization

Profiling and tuning systems — composite indexing, request batching, and caching strategies that measurably cut response times.

Artificial Intelligence

Developing AI-powered tooling, from real-time computer vision inference APIs to LLM-driven document intelligence platforms.

Power BI Analytics

Modeling star-schema data and authoring DAX measures to turn raw operational data into interactive, decision-ready dashboards.

Experience

Internships where I owned backend systems end-to-end — from architecture to deployment.

Software Engineer Intern — Founding Team

Answerbase

Sep 2025 – Feb 2026Remote
  • Led the design and implementation of Redis-based caching and request validation modules as the backend owner on a 3-member engineering team building a pre-launch SaaS platform.
  • Analyzed API performance using internal benchmarking and SQL-backed application metrics, optimizing REST API response times through Redis caching and request batching while documenting performance improvements for engineering reviews.
  • Implemented DTO-based request validation using class-validator, reducing API errors and improving backend reliability.
  • Collaborated with cross-functional engineering teams during architecture reviews, documenting technical decisions, supporting project planning, and improving backend integration processes.
  • Developed unit and integration tests with Jest for critical backend components, improving release quality and preventing regressions.
