I’m Tamiz. I build scalable systems.
Full-stack engineer with 2+ years building production systems — from AI-powered tools to real-time platforms and e-governance infrastructure. Currently engineering at Star Connect.
I build production systems that solve real problems.
I'm Tamiz Uddin, a full-stack engineer with 2+ years of experience shipping software that's correct first, fast second, and maintainable always. I work across the entire stack — designing APIs, modeling databases, and crafting interfaces that feel effortless.
My recent work spans AI-powered developer tools, real-time platforms, and e-governance infrastructure. I care deeply about clean architecture and the trade-offs behind every technical decision, and I enjoy the space where frontend polish meets backend resilience.
When I'm not building, I'm exploring new tools in the AI and web ecosystem — and turning the best ideas into real products.

Expertise & Architecture
How I approach each layer of the stack — from interactive frontends to resilient backend systems.
Frontend Architecture
- React & Next.js EcosystemApp Router patterns, SSR, ISR, and edge caching strategies for optimal TTFB.
- State & Data FlowComplex state machines, optimistic UI updates, and intelligent data fetching.
- Design SystemsBuilding scalable, accessible UI libraries with Tailwind CSS and Framer Motion.
Backend & AI Integration
- GenAI OrchestrationIntegrating Google Gemini Pro for codebase analysis, trend synthesis, and automated insights.
- Security & AuthJWT implementations, OAuth flows, and strict RBAC authorization logic.
- Database ModelingPostgreSQL/MongoDB schema design, complex query optimization, and indexing.
DevOps & Infra
- CI/CD PipelinesAutomated testing, linting, and zero-downtime deployment workflows.
- Cloud InfrastructureAWS/Vps provisioning, container orchestration, and serverless functions.
- Caching & PerformanceRedis implementation, CDN configuration, and intelligent database caching.
Architecture Deep Dives
Engineering is about trade-offs. These are real systems I designed, built, and shipped — with the reasoning behind each decision.
GIS-Enabled Property Tax Administration
Architecting a robust municipal platform that integrates interactive GIS mapping for property registration with automated billing and East African mobile money gateway integrations.
Context & Constraints
- Legacy systems lacked spatial awareness for land boundaries.
- Requirement: Real-time synchronization with local mobile payment APIs.
- Constraint: Must operate reliably in regions with intermittent high-latency networks.
Architecture Trade-offs
Chose a decoupled Client-Server architecture with a Vite/React SPA to ensure low-bandwidth data transfers while utilizing PM2 for resilient backend process management.
Database Modeling
Utilized MongoDB to handle both structured property data and GeoJSON spatial coordinates, enabling efficient proximity-based tax assessment and reporting.
Payment Integration
Implemented specialized webhook listeners and retry-log logic to guarantee transaction atomicities with external mobile money provider APIs (M-Pesa, etc.).
High-Performance CRM & Financial Management System
Engineering a unified digital ecosystem for global operations, integrating multi-currency financial tracking with real-time project lifecycle management and automated team collaboration.
Context & Constraints
- Requirement for strict financial isolation and multi-currency (USD, EUR, BDT) budget management.
- Need for real-time collaboration across distributed, remote-first teams.
- Constraint: Scalability to handle hundreds of simultaneous projects with deep audit trails.
Architecture Trade-offs
Selected a modular NestJS backend to ensure strong domain boundaries and scalability, while using Socket.io for low-latency real-time updates across the dashboard.
Database Modeling
Implemented a normalized PostgreSQL schema (via Mongoose/MongoDB in this instance) with complex relations between Projects, Clients, and Financial Metrics.
Payment Integration
Developed a robust receivables calculation engine with automated invoice status tracking and secure JWT-based access control for financial data.
How I Build Systems
Every project follows the same loop: understand the problem deeply, design for the edge cases, build incrementally, and ship with confidence.
01Understand the Problem
I start by mapping business logic, user flows, and edge cases — understanding what the system actually needs before writing any code.
02Design the Architecture
I draft the system design, choose the right database schema, and define API contracts and domain boundaries.
03Build Incrementally
I build features in decoupled modules, focusing on typed interfaces, clean code, and composability.
04Test & Harden
I load-test critical paths, audit dependencies, and make sure authentication and authorization are airtight.
05Ship & Monitor
I set up CI/CD for zero-downtime deployments and connect monitoring for proactive issue resolution.
What I Build
I help founders and teams ship scalable products — from ground-up architecture design to production deployment.
System Architecture
I design event-driven systems, multi-tenant databases, and resilient APIs built to handle real-world scale.
Rapid Prototyping
I turn abstract requirements into functional, production-ready products — shipping the core value fast while laying groundwork for growth.
Codebase Modernization
I transform legacy code into modular, typed, and testable systems using Clean Architecture — without halting feature development.
Performance Engineering
I diagnose and eliminate bottlenecks — from React render optimization to Redis caching layers and database indexing strategies.
Security Engineering
I secure applications against modern threats with strict RBAC, JWT auth flows, rate limiting, and input validation.
AI & Automation
I integrate LLMs and machine learning into core product logic — not as wrappers, but as first-class features.
Gemini AI Orchestration
Utilizing Google's Gemini Pro API to build intelligent features like automated codebase auditing (RepoInsight) and real-time trend synthesis (TrendPulse).
Intelligent Productivity
Designing focus-driven applications like the AI-Enhanced Pomodoro, which leverages LLMs to break down complex goals into actionable, bite-sized tasks.
Predictive Analytics
Deploying machine learning workflows to analyze cross-platform trends and visualize insights through interactive, time-series dashboards.
Impact & Testimonials
Numbers from the work I've shipped, and words from the people I've built with.
