Senior Software Engineer
I am a software engineer with about six years of experience, specializing in React.js and modern frontend engineering. I care about scalable UI architecture, performance, and clear collaboration with backend and product teams—and I enjoy strengthening systems with solid RESTful API design where it helps the whole stack.
At SSL Wireless, I progressed from Software Engineer to Senior Software Engineer, where I design and build scalable, reusable, and high-performance web applications for banking, payment, ERP, and enterprise platforms. Working with React.js, Next.js, TypeScript, Redux, TanStack Query, Ant Design, and Tailwind CSS, I have delivered solutions including NPSB-related products, payment reconciliation systems, financial analytics dashboards, scam detection tools, a municipality admin panel, an automated distribution system for a global brand, and a garment-sector ERP. In addition to hands-on development, I take ownership of frontend architecture, drive reusable design and state management patterns, contribute to technical planning and product decisions, collaborate closely with cross-functional teams, and resolve complex technical challenges to improve reliability, maintainability, and delivery speed.
Before SSL, I was a Software Engineer (frontend) at SVAM International Inc., where I maintained high-traffic React products, integrated REST and third-party APIs, and partnered with backend engineers on contracts and data flow—supporting loan provisioning, food distribution, online learning, and other initiatives with international teammates.
Earlier, as a junior full-stack developer at UniShopr, I shipped React.js and Next.js features, Node.js and GraphQL/Hasura APIs, and improvements across an e-commerce platform serving 500+ daily orders.
I keep learning across the stack, write technical articles on Hashnode, and hold certifications in Node, NestJS, React, SQL, and Python fundamentals.

My process from first read of the brief to shipping and learning
I don't open the editor first. I read, ask questions, and map the real problem behind the request — not just what's written, but what's meant. I use AI early to surface edge cases and blind spots I might not think to ask about.
Requirements as given are rarely the actual requirement. Before planning, I push back — why this approach? What if we did it differently? I treat AI as a sounding board here, pressure-testing ideas and exploring alternatives before committing to a direction.
Once I'm confident about the direction, I decompose the work into small, shippable pieces. I use AI here to stress-test my breakdown — it often catches missing edge cases or subtasks I glossed over. The output is granular enough to estimate accurately and clear enough that any team member can pick one up without a long briefing.
Deliberate, not habitual. I evaluate options against real constraints — team familiarity, scale, deadline, long-term maintainability. I use AI to compare tradeoffs quickly and flag things I might have overlooked. Then I commit and document the reasoning.
I estimate task by task, not just a final deadline. This exposes hidden complexity early, gives the team a shared sense of scope, and makes slippage visible before it becomes a crisis.
Before anyone writes code, I walk the team through the architecture, key decisions, and the reasoning behind them. Alignment at this stage saves days of rework later. I treat this as a two-way conversation — not a lecture.
Right person, right task. I factor in experience, growth goals, current load — not just availability. A task handed to the wrong person costs more time than the time saved by assigning it fast.
Not just a kickoff and then silence. During implementation, I use AI for code generation, boilerplate, and debugging speed — so I spend less time on the mechanical and more on the decisions that actually matter. I run short, frequent syncs to catch blockers early and make small course corrections before they become large ones.
After shipping, I look back — how accurate were the estimates? What created friction? What would I change? This isn't blame, it's calibration. A process that doesn't improve isn't a process, it's just habit.
I use AI across the full process — surfacing edge cases, pressure-testing ideas, comparing tradeoffs, and accelerating code generation. It handles the mechanical; the judgment, architecture, and decisions are still mine.

Open to working with open-source maintainers, contributors, early-stage teams, and researchers building meaningful products.
I enjoy contributing to many kinds of digital products — from internal tools and dashboards to customer-facing platforms, workflow systems, and scalable web applications.
I’m open to contributing to open source projects and collaborating with early-stage teams that need product-minded engineering support across web platforms, tools, and MVPs.
I’m interested in AI-related products, research-driven prototypes, and academic collaborations connected to web technologies. I enjoy turning ideas and experiments into usable tools, interfaces, and product-ready systems.
I'm currently employed full-time and take on selective collaborations outside work hours. Best fit: meaningful ideas, clear scope, and teams that value thoughtful engineering.
