Blockland India · October 2025 - June 2026
Full-Time | Guwahati, Assam, IndiaClient projects were stalling due to fragmented ownership — led a cross-functional team of 7 across frontend, backend, and AI workstreams,introducing sprint cadences and code reviews that took engagements from chaotic kickoffs to clean handovers across DACH and MENA markets.Real estate clients were losing leads to slow manual follow-up — designed and shipped a conversational lead qualification system using n8n andLLM-driven dialogue, with automated property shortlisting, a 7-day multi-channel follow-up sequence, and Google Calendar booking synced withHubSpot CRM, cutting response time from hours to seconds.Inbound calls were going unanswered outside business hours, costing revenue — built an AI voice automation system using Vapi and Twilio withLLM orchestration, TRAI DND/DLT compliance, and Hinglish conversation support, enabling 24/7 inbound handling without additional headcount.

Internship | Eschborn, Germany (Remote)The finance team was losing days monthly to manual reconciliation and recurring GoBD/ZUGFeRD compliance failures — built and shippedExpenseFlow, a multi-tenant enterprise SaaS with role-based dashboards, DATEV/ZUGFeRD/GoBD compliance, and JWT-secured architecture(React, TypeScript, FastAPI, PostgreSQL), cutting reconciliation time by 60% and compressing the monthly close from days to hours.German legal professionals lacked an AI that could accurately navigate statute hierarchies — delivered LAI via a Teacher-Student fine-tuningpipeline (Claude/GPT-4 teacher, Qwen3-27B via Unsloth/LoRA) with multilingual retrieval and statute-level citation, achieving over 85% retrievalaccuracy with sub-3-second latency on self-hosted infrastructure.Without structured handover, built systems risk being abandoned post-deployment — managed sprint ceremonies, onboarding, and authored full

Guwahati, Assam, IndiaModels were incompatible with edge deployment targets and manual conversion was consuming weeks — built a 4-step automated pipeline(PyTorch to ONNX to TensorFlow to TFLite to C arrays) that improved edge inference efficiency by 30% and saved roughly 2 weeks of manual workper model.Without accuracy validation, converted models risked silent degradation — tested across real-world scenarios and wrote reusable Pythonautomation scripts adopted into the team's standard conversion workflow.
