Backend Engineer \| Python · FastAPI · Node\.js · Spring Boot \| PostgreSQL · Redis · AWS \| Building APIs & Distributed Systems for Scale

## About

I build backend systems that survive real traffic — not just demo\-day demos\. Over the past two years, I’ve designed and shipped production APIs, real\-time messaging infrastructure, and distributed services using FastAPI, Spring Boot, Node\.js, PostgreSQL, and Redis\. I work across the full backend lifecycle: database schema design, API contract design, caching strategy, concurrency tuning, authentication/authorization architecture, and cloud deployment on AWS\. What that looks like in practice: • Scaled a real\-time chat backend to 100\+ concurrent users at sub\-100ms latency, replacing database polling with Redis Pub/Sub and increasing message throughput by 60% • Cut SaaS page load times by 25% and reduced API error rates by 20% at Answerbase \(founding team\) through SSR, request pipeline refactoring, and structured error boundaries • Built a Blog API handling 200\+ concurrent requests at <50ms average response time with JWT \+ RBAC — zero unauthorized access incidents across full testing I care about maintainable code and measurable performance\. Whether it’s optimizing a slow query, designing a clean REST contract, or choosing the right datastore for the job, I make decisions that hold up when user count grows from 10 to 10,000\. Currently open to backend and full\-stack roles at product\-focused startups and tech companies\. If you’re building something ambitious, let’s talk\.

## Work experience

Software Engineer \(Founding Team\) at Answerbase, Sep 2025 \- Feb 2026 · 6 mos, Remote, Joined as a founding engineer on a 0→1 SaaS product; owned end\-to\-end delivery of core features from API architecture to production deployment Redesigned RESTful API contracts with request batching and Redis caching, improving data flow efficiency by 40% and reducing redundant network overhead Cut page load time by 25% through server\-side rendering \(SSR\), intelligent lazy loading, and React state management optimizations Built 15\+ reusable UI components in React/Next\.js, reducing feature development time by 30% across product iterations Reduced API error rates by 20% by refactoring asynchronous request handling pipelines and implementing structured error boundaries Led architecture reviews on 3\+ core system design decisions directly influencing product roadmap and scalability planning

GitHub Repository Search Service · Personal Project at Personal Project, Nov 2025 \- Dec 2025 · 2 mos, • Integrated the GitHub REST API to aggregate metadata across 500\+ repositories into a queryable service\. • Designed filtering, sorting, and cursor\-based pagination endpoints — no latency degradation beyond 10,000\+ records\. • Optimised PostgreSQL queries with composite indexes, improving retrieval speed by 45%\.

Blog API System · Personal Project at Personal Project, Oct 2025 \- Nov 2025 · 2 mos, • Designed 10\+ RESTful endpoints using FastAPI with a modular architecture \(routers, services, schemas\) — reduced codebase coupling by 50%\. • Implemented JWT authentication and RBAC; achieved zero unauthorized\-access incidents across full test suite\. • Handled 200\+ concurrent requests with <50ms average response time through async request validation\. • Documented all endpoints with Swagger/OpenAPI; cut developer onboarding time by 40%\.

Real\-Time Chat System · Personal Project at Personal Project, Jul 2025 \- Aug 2025 · 2 mos, Remote, • Engineered a real\-time chat backend sustaining 100\+ concurrent users at sub\-100ms message delivery latency\. • Designed a multi\-room, event\-driven architecture using Redis channels — zero message loss under peak load\. • Replaced DB polling with Redis in\-memory streaming, improving message throughput by 60%\. • Built 12\+ REST endpoints for messaging, session management, and chat history; optimised PostgreSQL queries with composite indexes cutting response time by 35%\. • Tuned Spring Boot thread pooling to handle a 3× increase in simultaneous connections without performance degradation\.

AI Developer Intern at CIT, Aug 2024 \- Sep 2024 · 2 mos, Remote, Built a real\-time face recognition inference pipeline using Python, OpenCV, and MLP deep learning models, served via REST API at <200ms latency Improved model recognition accuracy by 15% through data augmentation, feature extraction tuning, and hyperparameter optimization Reduced end\-to\-end ML processing time by 40% and deployed model behind a backend API for live consumer use

JPMorgan Chase \(via Forage\) · Software Engineering Virtual Experience at JPMorgan Chase \(via Forage\), Mar 2023 \- May 2023 · 3 mos, Remote, Processed real\-time financial data streams across 5\+ market API endpoints for anomaly detection on trading dashboards Authored 20\+ unit and integration tests validating data integrity and API pipeline stability Completed an open\-source contribution as a bonus deliverable
