Backend Engineer @ Turbostart | Building async REST APIs with Python, FastAPI, PostgreSQL, MongoDB | GCP • AWS • Docker • CI/CD

About

I'm a Backend Engineer at Turbostart, building production Python services with FastAPI, PostgreSQL, MongoDB, and Google Cloud Platform. Over the past year I've shipped async REST APIs, passwordless auth systems, role-based access control, and CI/CD pipelines that auto-deploy on every push. 🛠 What I build: • Async REST APIs with FastAPI, asyncpg, and SQLAlchemy 2.0 • Passwordless auth, JWT/OTP flows, role-based access control (RBAC) • PostgreSQL schema design + Alembic migrations • MongoDB for unstructured / high-volume workloads • GitHub Actions CI/CD, Dockerized deployments on GCP 🚀 Recent shipped work: •At Turbostart: cut operational costs by 80% (₹5M → ₹1M) and reduced data verification latency by 97% (190s → 6s) through pipeline redesign and performance engineering. Built AI-powered report generation (Python + Gemini API) and architected OptiPlanner — a freight logistics optimizer using Google OR-Tools constraint programming. • LoanZone — a full-stack ML web app predicting loan default risk, reviewed and accepted by MIT Bengaluru. Later integrated a Google Gemini voicebot with Telugu + English so non-technical users can apply by voice •Football Management API — fully async (FastAPI + asyncpg + SQLAlchemy 2.0), passwordless email OTP, RBAC for coach/player roles, Alembic migrations, automated CI/CD that deploys on every push 🎯 Always interested in conversations about: • Backend architecture at scale (Python, FastAPI, Django) • PostgreSQL, MongoDB, Redis — schema design and query optimization • Cloud-native systems on GCP / AWS, Docker, Kubernetes • Roles where I can own services end-to-end and ship to production weekly 📩 Reach me: • Email: kmadanreddy656@gmail.com • GitHub: github.com/MadanReddy6 • LinkedIn DM always open

Work experience

Software Engineer at Turbostart, Jul 2025 - Present · 1 y 1 mo, Bengaluru, • Reduced operational costs by 80% (₹5.0M → ₹1.0M) and increased throughput by 70% by redesigning data acquisition pipeline stages and model selection logic — directly enhancing cost efficiency for the business. • Reduced data verification latency by 97% (190s → 6s) through algorithmic redesign and optimized data structure usage, demonstrating strong focus on performance engineering and software quality. • Built an AI-powered report generation system using Python and the Google Gemini API with advanced prompt engineering — automating production of 8-page real estate investment reports including valuation analysis, CAGR calculations, and risk scoring. • Architected OptiPlanner, a freight logistics optimization engine using Google OR-Tools to solve constraint programming problems — minimizing distance, time, and cost while respecting vehicle capacity constraints. • Working across the full SDLC with Python, FastAPI, PostgreSQL, GCP, and Docker, shipping production backend services on a weekly cadence in a fast-moving startup environment.

Web Development Intern at MITRAz Foundation, Aug 2024 - Jul 2025 · 1 yr, Puttaparthy, • Built a Loan Default & Credit Risk Prediction application — a quantitative credit risk modeling system using Decision Tree and XGBoost algorithms to predict loan defaults and evaluate financial eligibility, applied to a real fintech domain problem. • Developed the backend with Python Flask and MySQL for secure financial data storage and processing, covering the full application lifecycle from requirements through deployment. • Integrated Google Gemini 1.5 Flash with prompt engineering and the Web Speech API to build a multilingual AI Voice Assistant — enabling hands-free navigation and real-time EMI calculations in English and Telugu. • Completed an MIT Bengaluru-curated web development curriculum as part of the program, applying every concept directly to a real fintech use case rather than tutorial projects.
