Engineering Profile
Systems, Products & Technical Leadership
Previously at RIMES, I was the sole architect and engineer for the backend, data pipeline, ML, and infrastructure of Timor-Leste's national meteorological platform. It processes more than 1 TB/day through a three-node Airflow cluster with 97.64% task success. I also built LLM and RAG systems, emergency-alert infrastructure, and the data layer behind Bangladesh's live 15-day flood-forecast platform.
Earlier, I led engineering at Interactive Cares as the platform grew from 8K to 100K users, and worked remotely for Shipday. I am comfortable owning systems end to end: architecture, implementation, deployment, performance, reliability, and technical leadership.

A Free Knob: Decoupling Calibration and Predictive Skill in Threshold-Based Evaluation
ICLR 2027 submission · Datasets & Benchmarks
A matched-calibration audit for thresholded rare-event benchmarks. On released CasCast checkpoints, the cascade-over-backbone CSI gap falls from 0.1601 to 0.0339 after monotone recalibration; across 450 SEVIR contrasts, 51 reverse sign.

Counting People with Coverage: Distribution-Free Prediction Intervals for Crowd Counting via Crop-Consistency
Preprint
A post-hoc conformal wrapper for frozen crowd counters. Across four counters and four datasets, crop-consistency improves hardest-region coverage in all 12 model–dataset combinations; at matched coverage, intervals are 15% narrower than a label-trained uncertainty model and 29% narrower than isotonic recalibration.

Selected Case Studies
AI, Backend & Data Systems
Production platforms, applied AI systems, offline products, and open-source engineering.
Khatian Platform — Offline Land-Record Workstation
An installable, pilot-ready offline workstation joining OCR, two-person review, audit history, searchable khatians, and cadex parcel processing. Built with Tauri 2, Rust, React 19, embedded PostgreSQL, and local FastAPI model sidecars; 30 of 30 unseen sheets completed with 14,536 parcels and no invalid geometries.
GCF CDIS — Timor-Leste National Meteorological Platform
Sole architect and engineer for backend, data pipeline, ML, and infrastructure. The platform processes more than 1 TB/day across five NWP models and two satellites using a three-node Airflow cluster, with 97.64% task and 96.20% DAG success. Cached NetCDF reads fell from 30 seconds to 80 milliseconds.
SAHF Regional Climate Intelligence — Grounded RAG
A provenance-aware decision-support system for nine South Asian countries. It combines live ENSO, IOD, MJO, SEAS5, and GloFAS data with primary-source-verified historical reports to generate structured sector advisories and grounded chat, with country/region attribution guardrails, source traceability, fail-soft refreshes, and bounded multi-turn context.
Khatian OCR — Bengali Land-Record Extraction
Fine-tuned Qwen2.5-VL-3B with QLoRA for two handwritten Bengali land-record schemas. Mouza-disjoint held-out tests reach 0.965 core-field F1 on 10,509 full khatians and 0.947 on 5,122 index records, with Bengali-aware evaluation and bootstrap confidence intervals.
cadex — Cadastral Plot Extraction
Turns scanned, georeferenced mouza maps into numbered plot polygons. A ConvNeXt-V2 U-Net, watershed polygonisation, an eight-model number-reader ensemble, and roster-aware assignment recover and correctly number 91.7% of plots across 22 held-out sheets.
NLAS — Multilingual Livestock Advisory
A beta hybrid-RAG assistant for Bangladesh's Department of Livestock Services. It runs Qwen2.5-7B Q4_K_M through llama.cpp on a 4 GB GPU, retrieves from 5,353 QA pairs, handles Bangla and Banglish, and records 71% satisfaction among its small beta user group.
wis2downloader — WMO Open-Source Contribution
Refactored WMO's downloader into distributed Celery workers with async queues and pre-enqueue spatial filtering, reducing ingestion latency from about four hours to 130 ms. Merged upstream and used in CDIS production.
CAP v1.2 Multi-Country Alert Infrastructure
Sole architect of the validator, Django RSS feed, MQTT, and n8n dissemination design used by DNMG Timor-Leste and BMD Bangladesh through the Grameenphone mass-dissemination integration. pycap-validator is co-authored with Anindita Bose.
Research & Evaluation
Selected Research Projects
Research that informs how I evaluate and ship reliable machine-learning systems.
FreeKnob Audit — Calibration vs Predictive Skill
A model-agnostic audit for threshold-based rare-event evaluation. It applies matched monotone calibration without retraining or spatial reordering, then reports the skill contrast that survives alongside pooled frequency bias.
Vocabulary Shift in Open-Vocabulary Segmentation
Ongoing research on when conformal guarantees for open-vocabulary segmentation break under vocabulary change, and how to predict the break before deployment.
SPARRSO Flood Intelligence System
A side project developing a satellite-based national flood monitoring and forecasting prototype. Its 90 m susceptibility model reaches national AUC 0.83 and beats the HAND baseline in all eight divisions; a Brahmaputra pilot reduces held-out daily-discharge error by 36.7% at one day.
