M. Hamamul Fikri L.
Frontend-Focused Full-Stack Engineer
Software Engineer with 4+ years of professional experience building high-reliability web systems, responsive UI architectures, and mission-critical API integrations for aviation and enterprise logistics.
Built for High-Reliability Production Systems
End-to-end ownership from responsive React/Next.js interfaces down to fault-tolerant Node.js APIs and high-volume analytical databases.
Frontend Engineering & UI Architecture
High-performance responsive layouts, modular component systems, client-side caching, and low-latency state orchestration.
- Design-system-driven UI libraries with accessible, reusable primitives
- Optimistic UI updates & client-side query caching for sub-100ms perceived speed
- Ergonomic data-dense operator interfaces built for 24/7 operational floors
Mission-Critical APIs & Integrations
Seamless integration with complex third-party platforms (multi-airline reservation systems, logistics hubs), idempotent request handling, and automated retry mechanisms.
- Multi-airline PSS reservation & PNR synchronization engines
- Exponential backoff retries & circuit-breaking fault isolation
Databases & Analytics Pipelines
Synthesizing massive operational logs, indexed query optimization, and decoupled analytical read loads for real-time dashboards.
- Multi-stage MongoDB aggregations over millions of cargo telemetry logs
- Compound index tuning & zero-contention analytical query pathways
System Reliability & Security
Strict data authorization policies, fail-safe fallback routines during network degradation, and fault-tolerant transaction processing.
- Granular multi-tenant RBAC enforcing least-privilege across passenger & cargo records
- State-preserving session fallbacks & transactional rollbacks during link instability
- Containerized deployments with automated health checks for 24/7 SLA environments
AI-Augmented Engineering Workflow
Leveraging modern AI models (Gemini, Claude, ChatGPT) as daily engineering force-multipliers to accelerate feature delivery, explore edge cases, and streamline refactoring—while maintaining strict human verification over architecture, security, and production code quality.
- Faster prototyping of React/TypeScript components, complex MongoDB aggregations, and API schemas
- Deep root-cause analysis, edge-case simulation, and refactoring with Gemini & Claude
- 100% human-reviewed, type-safe, and production-tested code before every commit
Engineering Case Studies
Deep-dive architectural breakdowns of mission-critical aviation, cargo analytics, and enterprise logistics platforms running in production.
Airport Self-Service Check-in Kiosk Engine
Airport kiosk hardware requires continuous 24/7 availability. Network instability between physical airport kiosks and remote airline reservation systems risked session drops and lost booking records during high-traffic windows.
Delivered uninterrupted check-in operations during peak flight schedules, preventing counter congestion and meeting strict SLA uptime.
Engineering Solution
- Built an Express.js backend engine managing multi-passenger check-in transactions concurrently.
- Integrated multi-airline reservation APIs for automated PNR lookup, verification, seat allocation, and boarding pass dispatch.
- Implemented exponential backoff retries, state-preserving session fallbacks, and transaction rollback mechanics.

CIS 2.0 & Real-Time Cargo Analytics Dashboard
Heavy day-to-day air cargo operations generated millions of operational logs. Leadership required sub-second visibility into production volume and client-tier revenue without causing read contention on the operational database.
Replaced manual end-of-day spreadsheet reconciliation with real-time, interactive insights for flight cargo capacity planning.
Engineering Solution
- Designed an executive analytics dashboard using React and Ant Design.
- Structured multi-stage MongoDB aggregation pipelines to summarize historical data efficiently.
- Optimized indexing strategies and implemented query caching to minimize database execution time.

AWARES — Air Cargo Warehouse Management UI
Maintaining strict upstream-to-downstream data consistency across the air cargo lifecycle (from cargo acceptance, weighing, and storage allocation to final flight dispatch) while synchronizing state with multiple external third-party stakeholder systems where payload discrepancies or out-of-order updates could disrupt warehouse operations.
Eliminated upstream-to-downstream data drift across third-party integrations and accelerated ground cargo handoffs through a reliable, single-source-of-truth operator interface.
Engineering Solution
- Engineered deterministic client-side state orchestration and strict payload validation in React and TypeScript to keep cargo records consistent from initial intake to outbound dispatch.
- Integrated multi-party REST APIs on the frontend with real-time reconciliation views, immediately surfacing data mismatches between internal warehouse states and third-party systems.
- Built ergonomic, step-locked UI workflows in Tailwind CSS that prevent invalid downstream transitions until upstream third-party verifications are confirmed.

SIPP — Passenger Profiling & Security System
Aviation security personnel required low-latency full-stack interfaces and reliable backend query services to screen passenger risk profiles instantly, while strictly enforcing data authorization across sensitive profiling records.
Reduced security screening friction and strengthened data governance through an integrated, RBAC-fortified full-stack platform.
Engineering Solution
- Architected both the Node.js/Express.js backend services and the responsive React + Tailwind CSS screening interface.
- Implemented granular Role-Based Access Control (RBAC) across API endpoints and frontend views to enforce strict data authorization on sensitive passenger records.
- Optimized backend search and analytical query endpoints to deliver instant risk profile lookups and audit trails for security officers.

What You Can Expect When Working With Me
Beyond writing code—focusing on business impact, system reliability, and frictionless collaboration in remote engineering teams.
Translating Complex Business Rules into Intuitive UI
Aviation and cargo logistics involve strict regulations, multi-step verifications, and dense data tables. I focus on turning complicated operational requirements into clean, step-by-step interfaces that field operators can use fast without confusion.
- Step-locked workflows that prevent human error on operational floors
- High-clarity status indicators for multi-stage processes
End-to-End Data Consistency & Resilience
When integrating with multiple external third-party stakeholder systems, networks can drop and payloads can differ. I build systems with strict validation, idempotent requests, and clear reconciliation states so data never silently drifts.
- Graceful error recovery and state-preserving fallbacks
- Single-source-of-truth synchronization across 3rd-party APIs
Clean, Type-Safe & Maintainable Architecture
Fast delivery shouldn't mean messy code. I write modular React/Next.js components, enforce strict TypeScript contracts between frontend and backend, and keep business logic decoupled so the codebase stays easy for any engineer to pick up.
- Reusable component primitives & predictable state management
- Performance-first mindset (query indexing, caching, zero unnecessary re-renders)
Proactive & Async-First Remote Collaboration
Remote teams thrive on clarity and trust. I communicate progress early, write well-documented Pull Requests, ask the right product questions upfront, and take full ownership of features from technical design through production monitoring.
- Clear written communication, structured PRs, and self-unblocking habits
- Flexible daily overlap for US, EU, and APAC engineering standups
Professional Experience
4+ years of continuous production ownership delivering enterprise aviation and cargo technology systems.
