D34 Labs is a boutique software studio specializing in fintech, payment infrastructure, and scalable internal platforms. We bridge complex product vision and resilient system architecture.
Trusted by teams across industries
Four disciplines where senior judgment compounds — architected for the cost of failure in production.
Architecting robust payment lifecycles, virtual-account integrations, and reconciliation engines. We understand the cost of failure in financial data.
Designing event-driven microservices and high-throughput APIs that power modern web and mobile applications at scale.
Transforming messy internal workflows into streamlined tools that supercharge operational efficiency and reduce overhead.
Integrating LLMs, RAG, and recommendation systems into existing production environments to drive intelligent automation.
Real engagements, summarized honestly — the problem, our approach, and the outcome that mattered.
A lending platform's ledger drifted out of sync across providers, eroding trust in the numbers.
We rebuilt reconciliation as an event-driven pipeline with idempotent settlement and a full audit trail.
Reconciliation cut from hours to minutes; every dispute traceable to the cent.
Operations ran a growing business on fragile shared spreadsheets and manual exports.
We designed an internal platform with role-based workflows, approvals, and live reporting.
Manual handling down ~70%; a process that survives the team growing.
Keyword search kept missing the way customers actually phrase their questions.
We engineered retrieval-augmented (RAG) search over product and support content.
Relevant answers from messy data — the groundwork behind Hubly's smart replies.
Engagements summarized to respect client confidentiality. Our studio's DNA is built on years of experience inside Southeast Asia's leading fintech and payments companies.
Boutique doesn't mean small — it means specialized and high-end. Efficiency through direct, senior engagement.
Our team has built and maintained systems for Southeast Asia's leading unicorns, handling millions in transaction volume.
We don't just write code; we solve business problems — and give you a straight answer on ROI and technical feasibility.
We specialize in system observability and anomaly detection — reducing downtime and protecting your bottom line.
Sellers on Shopee, Tokopedia, Lazada, TikTok Shop and WhatsApp lose orders across a dozen scattered chat apps. Hubly pulls every conversation into a single inbox — with the order and customer right beside the message.
No spam. One email when Hubly opens. Unsubscribe anytime.
Four stages designed to answer one question: will this partner actually deliver? Yes — and you see it every week.
We talk through the problem, constraints, and what success looks like — in plain language.
Week 0A written plan: what gets built, in what order, what it costs. You approve before we build.
1–2 weeksWorking software in short cycles. You see progress every week, not only at the end.
OngoingDeployed, documented, and yours. We stay reachable after launch.
+ supportD34 Labs was founded on the principle that senior engineering judgment should be present at every stage of the lifecycle. Unlike traditional agencies built on layers of project management, we operate as a direct technical partner.
We specialize in “Day 2” software — systems that aren't just shipped, but built to be maintainable, observable, and evolution-ready. With deep roots in Southeast Asia's fintech ecosystem, we bring a production-first mindset to every engagement.
Boutique is the advantage: senior judgment on every decision, and a straight answer about what's worth building — and what isn't.
