WHO IS BEHIND THE SYSTEM?

Engineering philosophy, autonomous agents, and systems-level mindset.

I'm Tejas Jagdale, a backend developer focused on building reliable APIs, microservices, and AI-powered applications.

My work focuses on backend development with Python, FastAPI, TypeScript, Hono, PostgreSQL, and Redis.

I independently built a multi-agent startup validation workflow using LangChain and LangGraph for question generation, web research, and report generation.

I also build backend services for notifications, media, tracking, authentication, caching, rate limiting, and application storage, with hands-on AWS and Docker experience.

Backend Microservices

Built core, notification, media, tracking, and internal backend services using FastAPI, Hono, PostgreSQL, Redis, and TypeScript.

Multi-Agent AI

Independently built LangChain and LangGraph workflows for question generation, web research, and report generation.

API Performance

Used Redis caching and SlowAPI rate limiting, with sub-50 ms response times on most tested APIs.

Secure Backend

Implemented JWT, JWE, RBAC, token-based access control, and AWS S3 storage integration.

Backend Developer

Aug 2025 — Sep 2026

Built backend APIs, microservices, and AI-powered workflows using Python, TypeScript, FastAPI, Hono, PostgreSQL, Redis, and LangChain/LangGraph.

KEY ENGINEERING RESPONSIBILITIES:
Built and maintained backend APIs and microservices using FastAPI, Hono, PostgreSQL, Redis, and TypeScript, including core, notification, media, tracking, and internal API functionality.
Independently developed a multi-agent startup validation system using LangChain and LangGraph, implementing question generation, web research, and report generation workflows with OpenAI/xAI APIs.
Developed a real-time tracking microservice using Hono and Socket.IO, and built notification processing using BullMQ and Redis for asynchronous event handling.
Improved API performance using Redis-based caching and SlowAPI rate limiting, achieving sub-50 ms response times on most tested APIs; also worked on database indexing and query optimization.
Implemented secure authentication and authorization using JWT, JWE, RBAC, and token-based access control, and integrated AWS S3 for application storage requirements.
Used Langfuse to monitor and trace LLM workflows and collaborated with frontend and product teams to deliver backend features.
ENGINEERING IMPACT & BENCHMARKS:
  • ✓Sub-50 ms response times on most tested APIs using Redis caching and rate limiting.
  • ✓Independently built a multi-agent workflow for question generation, research, and report generation.
