Tactical corkboard compartmentalization: each technological discipline mounted onto dedicated pegboard matrices with pinned module specification tickets.
Unfiltered dispatches from international founders, lead engineers, and high-throughput product teams across distributed systems, multi-tenant engines, and production interfaces.
“Nazib architected our entire global platform from database schemas to responsive UI. He delivered a dual-domain CMS, automated workflows, and bulletproof security. He is our go-to engineering partner for every high-stakes project.”
“An absolute powerhouse on full-stack architecture. Whether crafting high-throughput Nest.js APIs or fine-tuning Next.js rendering, Nazib works with incredible speed and technical precision.”
“Flawless execution of multi-tenant inventory logic and Spatie role-based access. Delivered ahead of deadline with thorough documentation and test coverage.”
“His leadership in the DBMS project show took our team to the top 5 out of 40+ competitors. His database indexing and WebRTC live classes were the deciding factor.”
Reference phone calls, code audits, or past contract lead emails provided upon introductory mutual fit verification.
Full-stack software architect, database optimizer, and creative engineering generalist based in Dhaka, Bangladesh (UTC+6). Building uncompromised tactile systems at scale.
CALLSIGN: "Sayok Zaman"
ROLE: SOFTWARE ENGINEER
LOCATION: DHAKA, BD (UTC+6)
EDU: UIU BSCSE (3.80 GPA)
Engineering doesn't stop at API contracts. When I'm offline, I'm building interactive shaders, hacking together custom mechanical keyboards, or prototyping generative voice loops.
Three.js, Blender modeling, GLSL fragment experiments, procedural lighting for the modern web.
Faster-Whisper audio transcription, Kokoro TTS, retrieval-augmented assistants, and speech tech.
Indie game development in Godot, 2D physics engines, dungeon generators, and 2D mechanics.
Custom soldering, switch lubing (Krytox 205g0), custom ergonomic ortholinear keyboards.
Software should feel tactile, definitive, and structurally invincible. Rather than burying code underneath layers of abstract dependencies and vague aesthetics, I favor deterministic types, strictly modeled relational data, and snappy, responsive interfaces that respect user agency and hardware performance.
TypeScript and strict PHP types. Zero ambiguity at runtime.
Complex schematics, indexed relational integrity, zero redundant queries.
Deep responsive levels of tactile micro-feedback and minimal latency.
