Ambalsoft — AI Intern

Sep 2025 – Present | Chennai, India

Architected and operationalized localized LLM pipelines leveraging transformer-based encoder stacks, dense vector indexing (Faiss), and RAG orchestration to deliver deterministic retrieval with latency-optimized vector queries.

• Designed a hybrid retrieval layer combining dense embeddings, syntactic heuristics, and domain-specific tokenizers to optimize precision-recall for multi-document search.
• Implemented incremental ingestion pipelines with content fingerprinting and deduplication, enabling efficient near-real-time model updates without full reindexing.
• Integrated OpenRouter-based model routing with configurable fallbacks to maximize throughput while preserving cost-efficiency.

Freelance — Software Engineer

Jun 2025 – Present

Delivered multiple full-stack systems emphasizing developer ergonomics, observability, and immutable deployments across Next.js frontends, Node.js microservices, and serverless compute in AWS.

• Led API design using strict OpenAPI contracts and type-safe client generation to eliminate integration drift between frontend and backend.
• Implemented CI/CD pipelines with deterministic artefact promotion, canary rollouts, and synthetic monitoring to uphold SLA targets under peak load.
• Optimized HTTP and DB request graphs to reduce p99 latency via connection pooling, query profiling and edge caching strategies.

CuiSync — High-Security Restaurant Orchestration Platform

Nov 2025 – Present | Freelance

Leading a 4-member distributed team in constructing a hardened, air-gapped restaurant management substrate with absolute data sovereignty. Central CPU functions as a cryptographically sealed SQLite authority, enforcing encrypted, sub-50ms data propagation over isolated 802.11ac mesh with zero external egress. Implemented conflict-free replicated data types (CRDTs) via operational transformation, real-time state reconciliation, and QR-anchored invoice provenance.
