Software engineer building intelligent systems for logistics, maps, and data-heavy operations.
Long-running engineering work where performance has a business consequence—and every millisecond, route, and decision matters.

From enterprise integrations to government platforms and logistics intelligence—a career shaped by increasingly difficult systems.
Leading data-product and backend initiatives across address intelligence, route optimization, maps, and AI-assisted operations.
Led the next-generation address intelligence platform from concept to production, including a custom inverted index, spellchecker, verification tools, and area construction from 100M unstructured addresses.
14ms mean · 99%+ accuracy · 2M BDT/monthBuilt a Google ADK and Gemini agent to normalize addresses the primary parsing system could not confidently detect.
~50% of undetected addresses resolvedDesigned a vehicle route-optimization engine using OR-Tools and custom algorithms for multiple real-world fleet constraints.
~2.5M BDT/year projected savingsBuilt usage-based maps billing and high-performance nearest pickup-point queries using H3 hexagonal precomputation.
First SaaS client · 400K BDT/yearHow a complete address infrastructure emerged from continuous R&D to simplify operations, automate corrections, and handle growing order volume.
A visual introduction to spatial indexing and the decisions behind low-latency proximity search.
How to model fleet operations when the shortest path is rarely the complete answer.
I'm Alamin, a software engineer in Dhaka focused on making difficult operational problems feel simple.
Over the last five years, I've worked across backend systems, data products, geospatial platforms, and AI-assisted workflows. I'm most at home where software meets real-world complexity: imperfect data, strict constraints, and outcomes that can be measured.
At Pathao, I lead technical work on address intelligence and route optimization. APT 2.0 grew through 1.5 years of continuous R&D with a strong engineering team into infrastructure that improves over time, reduces manual effort, and helps courier operations handle growing order volume more reliably.

Clear models create better technical decisions.
Real users will always find the edge cases.
Durable systems come from shared ownership and engineering trust.
