Lalith Avinash Donkina 👋

I’m a software engineer who likes building real systems end to end: APIs, data pipelines, and product features that actually get used.
I care about clean architecture, reliability, and making things measurable (latency, quality, adoption, fewer manual steps).

What I work on

  • Backend + APIs: Java (Spring Boot), Python (FastAPI), Node/Express, REST, auth flows
  • Full stack: React, Next.js, TypeScript, modern UI + server logic
  • Data + reliability: SQL, MongoDB, validation checks, tests, monitoring, CI/CD
  • LLM systems: prompt chaining, retrieval, guardrails, evaluation mindset

Featured projects

🎧 Vanessa Voice POC (Twilio + Express + WebSockets)

Voice agent POC that answers calls, qualifies leads, and logs outcomes to a lightweight dashboard.
Repo: https://github.com/Avinash987/vanessa-voice-poc

🚨 Alarm Tracking System (Next.js + Express + MongoDB)

Full stack alarm tracking app with a clean UI and real time updates. Focused on strong typing + predictable state.
Repo: https://github.com/Avinash987/alarm-system

💬 Cyber Chat Room (TypeScript)

Small Gaming-Themed Real Time Chat Application client server flow and clean UI structure.
Repo: https://github.com/Avinash987/

Experience highlights

  • Built Python + SQL validation workflows that reduced manual effort by ~40%
  • Built an LLM multi-agent enrichment system that processed 10K+ contacts and cut manual work by ~40%
  • Shipped Java backend services + REST APIs on large enterprise platforms with strong testing coverage

Tech stack

Languages: Java, Python, TypeScript, JavaScript, SQL, C++
Backend: Spring Boot, FastAPI, Node.js, Express, REST APIs, OAuth2, JWT
Frontend: React, Next.js, HTML, CSS, Tailwind
Data: MySQL, SQL Server, MongoDB
DevOps: Git, GitHub Actions, Jenkins, CI/CD

Currently

  • Actively interviewing for SWE / Full Stack / Backend roles
  • Building more real-world projects with better testing, observability, and deployment
