GENERATIVE AI & AGENTIC AI ENGINEER

I build AI agents and RAG systemsthat work inside real products.

Generative AI and Agentic AI engineer working across LLMs, retrieval-augmented generation and tool-calling agent workflows — then shipping them full-stack, from data model to service layer to interface.

About & how I work

I am a computer science engineer from Hyderabad who ended up in applied AI because the hard parts turned out to be ordinary engineering parts: deciding what the model is allowed to see, what it is allowed to do, and how anyone can tell whether it worked.

Most of my work sits in two places. Retrieval — building the index, the hybrid search over it, and the prompt that answers only from what came back. And agents — giving a model typed tools, a bounded loop, and a definition of done that code can check.

I finish my B.Tech in Computer Science at Mohan Babu University in 2026 with a CGPA of 9.2, alongside internships at TMaxEdTech and ExcelR Edutech and two platforms shipped end to end. Underneath the AI work there is a habit from 200+ DSA problems in Java: get the data structure right before you get clever.

  1. 01

    Decide what the model sees

    Instructions, retrieved passages, tool schemas, history — and what gets cut. Most answer-quality problems are context problems, not model problems.

  2. 02

    Make the output a contract

    A fixed JSON schema at the boundary, so downstream code depends on a shape instead of parsing prose that changes with the weather.

  3. 03

    Keep the loop bounded

    Typed tools, a step ceiling and fallback handling, so a run that goes wrong fails visibly instead of spending quietly.

  4. 04

    Score it, then change one thing

    A generator–critic pass and a scored set beat a vibe check. Change one variable at a time so an improvement can be shown rather than claimed.

  5. 05

    Move slow work off the request path

    Notifications, scheduled pulls and database writes belong in n8n flows and background jobs, not in the user's wait.

02

What I build

Deciding what goes into the model's window — instructions, retrieved passages, tool schemas, conversation history — and what gets trimmed when it will not all fit. This is where most quality lives.

Retrieval-augmented generation over vector and relational stores, combining keyword and semantic search so exact terms — IDs, names, skills — and meaning both get found, then merging the ranked lists.

Tool calling, ReAct and plan-execute loops, and multi-agent orchestration with LangGraph and n8n — with typed tools and a step budget so the loop terminates on purpose.

Eval harnesses, schema validation, generator–critic filtering, model rotation, throttling and fallback handling — the parts that decide whether a feature survives its first real week.

My journey

From first lines of Java to shipping AI products.

2022 — 2026

B.Tech, Computer Science & Engineering

Started at Mohan Babu University, Tirupati. Java and DSA came first — 200+ LeetCode problems — and the habit of naming the data structure before writing the loop stuck around.

MAY — JUN 2025

Core Java, properly: ExcelR Edutech

A six-week Java internship under APSCHE, spent on OOP and small projects. The first code I wrote to somebody else's specification instead of my own.

FEB — JUL 2026

Agents in production: TMaxEdTech

Python REST APIs orchestrating LLM agents, tool calling and RAG pipelines, the schemas holding conversation history and embeddings, and interfaces for watching prompt runs and evaluation results.

2026

Two platforms, two problem shapes

HireGen AI — a generator–critic assessment engine with a real service layer around it. Vivāha Atelier — a catalogue and enquiry pipeline where the AI is not the point and the polish is.

NOW

Building, measuring, job-hunting

Looking for an entry-level Generative AI or Agentic AI engineering role, and continuing to build retrieval and agent projects in the meantime.

09

Why hire me

Four things that show up across every project.

01

AI inside real products

Every model I have shipped sits in a complete product with auth, a database and an admin path — not an isolated notebook demo.

02

Full-stack ownership

Front end, API, schema and the AI layer. I built the data model and the interface for both platforms myself.

03

Reliability by design

Model rotation, throttling, fallback handling and schema validation ship with the feature, not after the first outage.

04

Fundamentals underneath

200+ DSA problems in Java, plus DBMS, OOP and computer networks. The AI layer is new; the engineering is not.

10

Lab

Smaller experiments and explorations that don't need a full case study.

Agentic AI

Tool-calling ReAct loops

Small agent prototypes exploring plan-execute loops and multi-agent orchestration with LangGraph and n8n.

Prompt engineering

Structured-output reliability

Testing context engineering, guardrails and schema-forced output across GPT-4o, Claude and Gemini.

Retrieval

Hybrid retrieval playground

Comparing hybrid retrieval strategies over VectorDB and Postgres for grounding answers in real documents.

Local LLMs

Self-hosted serving

Running Llama 3, Mistral and Qwen through vLLM and Ollama to compare latency and cost trade-offs.

Evaluation

Prompt regression sets

Small scored test suites that run on every prompt change, so a regression shows up before a user finds it.

Automation

n8n workflow patterns

Reusable scheduled-pull and notification-routing patterns lifted out of BizIntel and Royal Occasions.
