G Sudarshan
Sastry

Full-stack AI engineer building LLM, RAG and voice-agent systems that run in production.

I take AI products from requirement to deployment: FastAPI and Next.js services, vector retrieval, real-time voice, and the multi-cloud infrastructure underneath. First author at IEEE IGARSS 2025.

AI Engineer

Anju Siima Technologies Pvt. Ltd · Product Development
  • Building a multi-tenant AI voice-calling platform: bots with versioned prompts, phone and browser test calls, a call queue with retries and circuit breakers, campaigns, recordings, transcripts and LLM post-call analysis (FastAPI, MongoDB, LiveKit, Docker).
  • Made every speech and model vendor a plugin (Sarvam, Deepgram, ElevenLabs, Murf, Fish Audio, Gemini, OpenAI) and benchmarked 12 TTS models, so each bot can switch providers on latency, cost and language quality.
  • Shipped multilingual calling agents (English, Hindi, Telugu) with tool calls for demo booking on Google Calendar, scheduled callbacks and hand-off to a human.

Associate AI Developer

Freedom With AI
Joined as AI Intern (Nov 2025), converted to Associate AI Developer (Jan 2026), full-time from Apr 2026.
  • Delivered 14+ LLM/RAG systems across 9 client accounts with provider-agnostic LLM routing (retry and fallback), vector retrieval, FastAPI and Next.js services and n8n event orchestration, owning each from requirement to deployment.
  • Productised a webinar and call attribution platform (Next.js, PostgreSQL/JSONB) that reconciles 4 mismatched export sources into one schema across 7 migrations; one codebase redeployed to 5 tenants.
  • Recovered ~37,000 validated CRM contacts and 61 automations from a broken migration by mapping an undocumented internal API.
  • Shipped an AI tool suite on Cloud Run (124 commits): prompt enhancer, AI tool finder, job-prep assistant, a Chrome extension and a Claude-based assignment auto-grader.
  • Operated 16+ Dockerised services on a six-VM AWS/GCP/OCI fleet (43 Dockerfile/Compose artifacts) with SSH runbooks; distilled a 49,737-message mail corpus into a ~5,000-pair support knowledge base; ran knowledge transfer for ~12 colleagues.

Software Engineer

Deep Algorithms
Intern from Mar 2025, Software Engineer from May 2025.
  • Built a DDoS detection path with packet-to-flow aggregation computing per-source packet rate, source-IP entropy and protocol-mix features, evaluated against tunable thresholds for volumetric and protocol-layer attacks.
  • Implemented TLS fingerprinting from ClientHello metadata (cipher suites, extensions, version) so detections key on client-stack identity rather than source IP; owned feature specs and acceptance tests with QA.
Dec 2024 – Mar 2025
Mandi
IIT

Research Intern

CAIR Lab, IIT Mandi
  • Wrote STM32 BLDC motor firmware in C with timer-driven PWM commutation and closed-loop speed control, from bare-metal bring-up to bench validation.
  • Fused multi-sensor gas readings on Arduino using per-sensor calibration curves, drift compensation and noise filtering; wrote the firmware docs and test plans the lab adopted.

AI-ML Intern

AKOSCOWL DOT INVENTIONS Pvt. Ltd.
  • Designed drone power and control electronics in KiCad and built a ROS/Gazebo model (URDF airframe, sensor plugins, flight-controller-in-the-loop).
  • Developed obstacle-avoidance planners emitting MAVLink waypoints through QGroundControl mission flows, validated in simulation before flight testing.

Things I've built

LLM tooling, automation and local-first AI, built end to end.

LLM + rules

Match Check

Deal-breaker detector for matchmakers. Claude extracts deal-breakers from free-text bios (an exact quote or null); a deterministic engine scores the match, so every verdict is traceable.

Live product

AI tool suite

One Next.js app on Cloud Run with a prompt enhancer, AI tool finder, job-prep assistant and a Claude-based assignment auto-grader, plus a companion Chrome extension.

AppFlowy-AI

An offline AI workspace: SQLite canonical store, two-way YAML projections, filesystem watchers for conflict-free edits, local vector search and an agent router dispatching to Ollama models.

RAG

Content engine

Multi-tenant script generation combining vector retrieval over a research corpus with live search and trend ingestion, running on two clouds.

Obstacle Avoidance in Drones Using Deep Reinforcement Learning

DQL and DDPG agents trained in Unity3D compare 2D LiDAR against depth estimation for fixed-wing UAV obstacle avoidance. LiDAR won for real-time control, and the paper proposes hybrid sensing for production.
