Official Hello technology account, sharing tech insights and developments.
This guide outlines practical facilitation methods for agile retrospectives—including preparation steps, divergent and convergent techniques, opening and closing rituals, handling ad‑hoc teams, using retrospectives as training, and fostering self‑management—to continuously improve team effectiveness.
The Smart Matching Engine for Haolo’s ride‑sharing service ingests driver and passenger orders via Kafka‑Flink pipelines into Elasticsearch, then applies multi‑stage matching—nearby search, itinerary‑based filtering using ETA, angle, distance, route‑similarity and shared‑mileage calculations—and finally ranks results with evolving pre‑sorting and algorithmic models, including PMML and deep‑learning, to optimize driver‑passenger pairing.
The article outlines how R&D organizations evolve from functional to cross‑functional Scrum teams using a 3‑3‑5‑5 framework, physical and electronic Kanban (Jira with plugins), defined domain, project and story owners, and data‑driven metrics to monitor effectiveness, align product and research, and continuously improve value delivery across design, implementation and operation.
The talk demonstrates how to apply Domain‑Driven Design and microservice architecture to an e‑commerce voucher platform by defining problem spaces and bounded contexts, prioritizing boundaries over aggregates, using layered‑on‑demand infrastructure, and following SOLID principles to achieve clear, maintainable services.
At the HiPM Product Innovation Summit, Haro’s senior product expert shared a five‑point framework and a three‑stage evolution of intelligent bike dispatch, revealing how data‑driven, human‑machine collaboration can transform chaotic bike distribution into efficient, asset‑maximizing operations.
By launching an MVP, standardizing SOPs, instituting speaker quality controls, implementing a Kirkpatrick‑based feedback loop, and enhancing participation through user‑centered tweaks, the TechTalk platform transformed from ad‑hoc sessions to a stable, high‑impact bi‑weekly event, illustrating the power of iterative, cross‑functional process improvement.
Hello Ride boosts mobile development efficiency by empowering technical PMs as bridges between business and architecture, prioritizing demand value, and upgrading technology through modular, containerized (e.g., Flutter) and standardized components, enabling cross‑platform reuse, faster decision‑making, and reduced costs amid rapid business expansion.
The initiative introduces fault‑drill and chaos‑engineering practices—defining steady‑state metrics, injecting real‑world failures in controlled experiments, automating continuous production tests, and limiting blast radius—to detect weaknesses early, accelerate fault location and recovery, boost emergency response metrics, and foster a resilient engineering culture.
By treating postpartum parenting as a structured project—defining kickoff, phases, milestones, daily and weekly task iterations, stakeholder roles, communication protocols, and continuous retrospectives—the author successfully coordinated mother, baby, and family activities during 143 days of maternity leave, achieving all goals and returning to work.
The article details Haolo's end-to-end AI platform—built on Hadoop/Yarn with Spark ML, XGBoost and TensorFlow—and explains how its matching recommendation engine, transaction-ecosystem governance models, and intelligent uplift-based marketing system jointly boost carpool efficiency, safety, user retention, and ROI.
