Shashank Tiwari
AI Engineer
AI Engineer specializing in RL infrastructure and LLM agent systems — built production platforms serving Microsoft and Google, and fine-tuned sub-billion parameter models to within 2% of GPT-4o-mini. Experienced across the full post-training stack: data collection, reward design, agent orchestration, and evaluation on Kubernetes.
Work Experience
DeccanAI
AI & Backend Engineer
Oct 2025 – Present|Hyderabad, India
- ▸Built a production RL platform (Python, FastAPI) for human-in-the-loop golden trajectory generation, coordinating 500+ annotators and driving $10M ARR.
- ▸Architected Stark-Forge, a distributed backend framework that runs isolated services on Kubernetes; added pluggable SQL, JSON, and Python verification services with support for multiple agent runtimes.
- ▸Designed evaluation and verification pipelines by defining success criteria and automated checks for SQL and code tasks, improving end-to-end task success rate from 41% to 68%.
- ▸Owned delivery of 20+ production MCP servers that generated verified execution traces; the Jira MCP server handles 10,000+ requests/day in production evaluation pipelines used by Microsoft and Google.
- ▸Fine-tuned Qwen-0.5B for text-to-SQL on Spider using Agent-Lightning, reaching within 2% of GPT-4o-mini accuracy with 3× smaller scale and 10× lower inference cost.
Deutsche Bank
Software Engineer
Jul 2024 – Oct 2025|Pune, India
- ▸Architected a RESTful ETL pipeline (Spring Boot, Airflow, SQL) automating 10,000+ alerts/day across financial workflows; reduced data load time by 40% and freed 3 ops engineers for higher-value work.
- ▸Engineered high-concurrency microservices with Memcached and Java ExecutorService for business-critical internal systems; reduced outages by 30% and improved P99 latency from 820ms to 310ms for 5,000+ daily users.
AiDash
Machine Learning Engineer Intern
Jan 2024 – Jul 2024|Bengaluru, India
- ▸Built a Python ML SDK abstracting Kubeflow and Airflow; compressed pipeline setup from 2 days to 3 hours, adopted by 12+ data scientists with 30% faster experiment cycles.
- ▸Developed a human-in-the-loop Annotation Service with QGIS for raster validation; eliminated 40% of manual GIS effort across 8 annotation campaigns.
